Master Jon2, wag ka maniwala sa kanila. Mahilig sila magkalat ng chismis. ::)
Si Master Nelson de Leon lang ang proven hakot master dito.
Back to the topic: Maganda talaga yung LSi series, very smooth and slightly mature sound. It sounds best with neutral to bright sounding gear, IMO. It might get a bit wooly when coupled with a warm-sounding electronics.
When partnered well, these speakers can rival items selling for twice as much.

I love the tall profile. The tweeter height is right about perfect.. :D

Last Tuesday was my third time to hear an LSi9 pair. I’ve heard them with the Marantz PM8003, the Harman HK 990 and a VTL amp (dunno the model, but it had 8 KT88s… 4 per side). I particularly liked them with the Marantz and the VTL. Both gave justice to these magnificent speakers, as the Marantz livened up the dynamics, while the VTL provided an enveloping sound and air around instruments. The Harman was also good, but the partnership got exceedingly warm to my taste.
Going back to the speakers: Build quality is excellent. It easily passes the knock test, and the weight is truly reassuring. Aesthetics is top-notch, save for that white print on the tweeter waveguide. The sonic character is lush, smooth and refined. It’s the type of speaker that draws you into the music. These speakers can be a bit reserved in the upper registers (when used for movies or electronica), but natural music presentation is its true raison d’etre. Jazz vocals are intimate and the wind from brass instruments reverberate with a vibrant burnished tone. String instruments become pleasingly lovely with that balmy resonance from the woodwork. Percussions come to life with a controlled and satisfying snap. Dynamics is truly there, as long as you have the right amp for the job. Testing some fairly complex tracks showed that these speakers don’t easily congest (a problem I notice with lesser speakers).
I would’ve wanted to test the LSi9s with some classical works, but I forgot to bring test discs. :D However, I’m sure they’d do great in those as well. It’s astonishing how this decade-old design can keep up with the current offerings, and still offer amazing value (great sound for the outlay).
The LSi M may be coming, but the outgoing LSi models are still shining brightly. It’s hard not to recommend them at their respective price points. :)

Sir Stagea,
A noob question, I'm currently using Marantz PM8003 paired with MS Mezzo 2 but I'm planning to replace this babies with Polk Rti9 coz I like their lows extension, ang inaalala ko lang sir ay is my Marantz 100w@4ohms are enough juice to drive this power hungry Polks?
TIA :)

Hi Ron,
Nice gear you have there. The Mezzos are excellent speakers too. :)
The PM8003 could power them just fine if you don't play very loud or if you're in a confined space. Amps that are capable of extracting the full dynamic capability out of these speakers are truly hard to come by, but even lesser-powered amps would still sound good (and I think that really matters more)... as long as we're not talking about very low-power amps. :)
Even the HK 990 at a claimed 300WPC @ 4 ohms did not get these speakers to audibly distort before it did. How often do you play at levels that would take advantage of this anyway?
Also remember that the doubling of power can only raise the volume by about 3dB (with thermal compression, often it's even less). This gives you additional scale and dynamic headroom for transients (or to simply play louder), but it does not make a weaker amp less capable to sound good (as long as the desired playback volume remains within the weaker amp's limits).
It's like buying a Camry or an Accord, and choosing between the 4-banger (weaker amp) or the V6 (stronger amp). Just because the 4-banger has less power does not transform the car into a bad one. The V6 variant can accelerate and go faster with less effort, but aside from that, they're still the same car overall. :)
Just my tuppence worth. :)
-
Very well said sir, you're right Mezzos are very nice speakers, kaya lang since na inilagay ko sa bedroom namin ang set up ko madalas gamitin ng wife ko and my son, and mostly they are playing their favorite bassy music like R&B and Pop at doon nagsimula bitin daw sa bass ;D ;D.
Well, at least malinaw na sa akin na kaya pa rin e-drive ng Marantz PM8003 ang Polk Lsi9.
Sir Stagea, Thanks and Good day.
(Sorry po sa OT)

You're welcome sir. An LSi9 pair would definitely have more bass than the Mezzo 2s. :) However, are you sure that this would be enough to satisfy your family's bass-heavy taste?
Have you considered adding a sub?
-
the LSi 9 at 45+ K a pop, and its approaching its 8th year of existence (launched/reviewed circa 2002 in the US, launched worldwide in 2006) is still a worthy buy despite its age/technology/materials employed.
LSiM supposedly replaces them for 2011 (featuring a dedicated midrange)

Sana makarating dito sa PH ang LSi M series para mapalitan ko na ang luma kong Polk Monitor 70 ;D ;D ;D
Mapapalitan na yan for sure. You can have it ordered thru Sanjay or Topper. ;) 1 &1/2 month ata bago dumating. :D
And don't forget to invite me and master Stagea for auditioning pagdating. ;D

Looks like mabibitin pa din sila sa bass on a pair of BS. Baka sa FS mabitin pa din. Probably adding and integrating a sub would also be a better option.

Sir Marc,
The LSi9s I got from AV Shop are perfect! Best sounding bookshelf speakers for me.
Works so well with my Onkyo A9755, whether the source is CD, Vinyl, or even an ipod via a DS-A3 dock the sound reproduction is so good I'm thinking of buying a second pair for backup heheheh
And also James was very knowledgeable, accommodating, and helpful when we visited your shop for an audition... kahit Christmas eve na :) not like the other Polk Audio Dealer in Rockwell whose salesman said that all Polks sound the same "kase Polk yan e" heheheh
I highly recommend The AV Shop :)
Thanks again Marc!

Polk is under rated but Ganda talaga ng lsi series. High end sound at an affordable price. :) I plan to,push the lsi series so people can have a better appreciation of the brand. :)
Can't wait for the LSI M to be introduced. :)

Sir congrats s new speaker mo, great chose. Polkaudio lsi series are great sounding speaker, very good in imaging and have deep soundstage.I have a pair of lsi7 powered by HK and the result is warm, sweet and a little laid back sound. :)
-
Sir Jon2,
Thanks, initially I thought it sounded good sa AV Shop hooked up to a HK home theater receiver, then soon as I got home I hooked them up to my ol' HK AVR 2550... kulang sa power but still sounded good with CDs. Finally after a week when I got my new stereo receiver noticed the sound was improved even further!
I love the bass response of the LSi9s! No need for a sub, besides wala din port for a subwoofer yung receiver ko. The A9755 is driving the LSi9s with 300w at 4ohms, didnt even reach half the volume range and I'm already very satisfied.

Congrats sir. These speakers indeed sound great with most amps, but would sound their best with matching gear. :)

I heard the LSI 7 yesterday at AV Shop. It sounded great for HT considering it was "only" an Onkyo 608 powering it.

Yup, though it didn't have the matching LSI center. Polk CSI A6 was doing the center channel duties.

Thanks StageA, the LSi9s put an end to my long hard search for a pair of speakers than can satisfy my ears :D IMHO, the LSi9s paired very well with my amp.

I was able to hear the Polk LSi7 today matched with the Onkyo C-S5VL SACD Player and A-5VL Integrated Amp. They surprisingly work very well together. :) I was able to compare it to the pricier B&W CM5 as well, partnered with the same gear.
The LSi speakers sounded best on-axis (fully toed-in and facing the listener), and this is probably because ring radiators are known to roll-off quite a bit off-axis. The CM5s on the other hand sounded a bit shrill-on axis, and preferred being pointed straight forward.
The Onkyos sounded brighter and snappier when connected digitally (we were playing plain-old Redbook CDs), and matched the LSi7s better in this configuration (improving PRAT). The CM5s were a bit too forward and fatiguing with this setup, and sounded much better with an analogue connection (more relaxed sound, and with more weight on vocals). The SACD Player and the matching Integrated Amp have different DACs and supporting circuitry, which may be the reason for this variance.
With the ideal setting for both speakers (toed-in and connected in digital for the LSi, and aimed straight-forward and connected in analogue for the CM), both were spectacular speakers for their respective price points. I'd be very happy with either. :)
I was most surprised with the Class-D amp, though. Had I not known that I was listening to a PWM amp, it would've been quite indistinguishable from a typical Class-AB amp. The output was clean, and the amp didn't show any sign of stress while driving these speakers. :) Green technology has come a long way. It's like a guilt-free way to enjoy music. ;)
Thanks Marc and James! :)

Great review master stagea, they say that lsi's are very good in sacd format, do you test it at sir marc avshop?

STAGEA - Which class-d amp was that? happen to have a link to more info?
-
Thanks StageA, the LSi9s put an end to my long hard search for a pair of speakers than can satisfy my ears :D IMHO, the LSi9s paired very well with my amp.
Lsi9s is my first choice,bec of its extended bass but i was out of budget so i settled only to Lsi7. Now i don't have regrets on this speaker, good for small or medium room.Now,i mount my lsi7 and all i can say is the bass is more deep and strong.
-
STAGEA - Which class-d amp was that? happen to have a link to more info?
Onkyo A-5VL.

STAGEA - Which class-d amp was that? happen to have a link to more info?
Hi Manoj,
It's the Onkyo A-5VL. It's not a really powerful amp (90wpc @ 4 ohms), and the output isn't so dynamic. However, it's very clean and enjoyable... reminds me of Rotel's Class-AB integrateds. :) The price isn't much cheaper than a Rotel, but it's the novelty of having a built-in DAC and being a PWM amp that got me thinking. :)
We turned it up, and the amp remained stone-cold. :D
-
Hi StageA,
I'm also a fan of the Onkyo A-5VL. I listened to this amp paired with a pair of sand-filled QAcoustics 1030i's. Its a clean sounding amp even high volume.. sayang lang the store here didn't have the C-S5VL so they hooked up a DX-7555 instead.
I was looking at getting this amp before but I didnt think the 90w/ch would be enough power to drive my LSi9's so I went for a more powerful amp.
-

Good to know that you also liked this amp. :) There's nothing wrong with a more powerful amp. That's always a welcome move. The A-9755 is the big brother of this amp after all. :)
I was just pleasantly surprised with the performance of this relatively small and inexpensive PWM amp. I've been using bigger linear amps for the most part, and it made me realize that good things can still come in small packages. :)

Sir, back to the LSi7's how is it compared to the LSi9? or to other bookshelf speakers at the same level (except for the CMs which you've mentioned on your review)? Or maybe how will it fair with an analog source?

The LSi7 sounds similar to the LSi9. The LSi9 has more scale and oomph, and is slightly more neutral in the midband. However, I like the fact that the LSi7 is less particular with mounting height.
I have not tried it with an analogue source, but I suppose it'd work just as well with analogue as long as the front end / phono stage / amp combination tips towards the bright-neutral side. The speaker itself is a bit warm to my ears (probably because of the top-end roll-off), so I'd prefer it with gear providing vigorous highs.

Marc,
Thank you for letting me audition the Polk Audio LSi 7 + Harman Kardon HK 980 a while ago.
I was in the vicinity of your shop and had extra time hence decided to give you guys a visit
Let's just say Jennifer Warnes' 'Rock you gently' bookmarked the speakers for my next upgrade
Hope you can 'borrow' an LSi 9 so I can compare next time I visit.
Cheers!

Will work on it. :)
By the way, the Hk 980 was on direct mode so the treble and bass adjustments werent working. I tried it again with direct mode off and enhanced the treble. It sounded a lot better pa. :)

The LSi9 is cleaner-sounding, imho. Take out the resonant/nasal character that sometimes comes out of the LSi7 and extend the lows a little more, then you get the LSi9.

Well I'll come back with my HK3470 one of these days and let's hear the LSi 7's once again.
I'll SMS you when I'll drop by so hopefully an LSi 9 will be lying there somewhere LOL. ;D
I'll also be bringing my CDs over.

Ok,
After much 'auditioning' with my HK3470 (since friday and saturday afternoon) and getting the go signal from my hubby who went with me at AVShop to hear the 'upgrade' speakers, and after an expensive 'bribe' for the approval (yes, corruption starts at home)
Its official - my upgrade is an LSi9.
Can't wait to bring them home after the formalities (aka full payment).
Oh, my hubby's also still recovering from the sticker shock. :o
It's a first time for me to get a flagship bookshelf of a known american marque, a far cry from DIY speaker contraptions I had to put up with when I was still starting out in audio during my elementary till high-school days.

Yeah, it actually trumped out a more expensive B&W 683 in the A/B listening tests using my receiver, to thnk the 683 is a floorstander.
What mesmerized me with the LSi9 over the LSi7 is its ability to 'disappear' when playing music. The sound staging is just so wide when I close my eyes, the sound seems to be coming from somewhere else except from the physical location of the speakers.
My RTiA3 can almost go as low as the LSi9s, its midrange and highs are also as potent, but what I paid for as 'upgrade' is the experience of the speakers disappearing in the listening area,a feat usually found in speakers way above the PhP100K mark.
I believe that's the goal of every manufacturer/designer since the invention of the loudspeaker - to create speakers that disappears in the listening area and render music with the closest fidelity to the original recording as possible, at the most affordable price.

Nice upgrade mikeer, I heard the lsi9 2yrs ago and it was paired with a marantz intergrated amp 6003 yata ,it just sounds stunning ang ganda pa ng finish niya thats one of my dream speakers congratulations. :D.
-
Congrats Bro. The LSI 9 was a very close contender against the RTi A9 for my fronts. Very very nice sound to my ears.

Thanks Blue_123, lncc63
I actually also brought in my Marantz PM45 Integrated Amp for good measure against the HK3470 for the LSi9s - It held its position with vocal music / acoustics (not much bass - more on midrange and highs) but the LSi9s hunger for power comes in when playing very bassy music, hence the need of a beefy/high current amp if you want to satisfy your inner cravings for loud bassy music on the LSi9s.
the PM6003 is the 21st century reincarnation of the vintage PM45 which won the what! hi-fi 5 star amplifier of the year in 1988. both have LDPS (for 4 ohm stability)
Since AVShop also has a pair of the RTiA7s and RTiA9s there, I also went ahead and tested them against the LSi9 - The A7s lost, A9s were almost but not quite. Both delivered really low bass and the RTi Ax's stellar imaging and brightness but they dont have that stealth capability - you know the big speakers are there in front of you even if you close your eyes.
I wish there was an LSi15 to compare it with - that would have given the A9s a run for its money since they're almost at the same price range (70-80K)
-
Ok,
After much 'auditioning' with my HK3470 (since friday and saturday afternoon) and getting the go signal from my hubby who went with me at AVShop to hear the 'upgrade' speakers, and after an expensive 'bribe' for the approval (yes, corruption starts at home)
Its official - my upgrade is an LSi9.
Can't wait to bring them home after the formalities (aka full payment).
Oh, my hubby's also still recovering from the sticker shock. :o
It's a first time for me to get a flagship bookshelf of a known american marque, a far cry from DIY speaker contraptions I had to put up with when I was still starting out in audio during my elementary till high-school days.
Wow congrats!
-
Well said Bro. You put into words my precise sentiments. After deciding to go with the A9, I also put down a mental note to eventually have a separate system for music with LSI9 fronts. I'll probably tap the receiver's pre-outs and use a beefy stereo power block.
I'm wondering why you didn't bring them home immediately?
-
Congrats Bro. The LSI 9 was a very close contender against the RTi A9 for my fronts. Very very nice sound to my ears.
Aside from a narrow listening window, there is little to fault in the LSi9 for the price that it's selling for (especially if you're like most of us whose hearing tapers much beyond 14kHz). The sound character is very unlike the RTi, as it is less forward and is a bit more mature.
The narrow listening window is typical of most ring radiators, hence it's often best to have these speakers face the listener directly (and always mount them at the proper height). The upside is undistorted HF reproduction, afforded by superior diaphragm rigidity and damping.
The woofers also reflect Polk's obsession in making this a low distortion speaker. The cone is designed to damp its own resonance.

Because they're so underrated / unappreciated.
Well who can blame the buyers?
At the price you're paying for an LSi series speaker, people would rather go for 'image' or 'status symbol' speakers like B&W 6 series or CM series / Paradigm Reference

You mean to say that these series of speakers are more of "pogi points" rather than having the SQ one is looking for? Have you compared them with the LSi series?
I'm sorry but I happen to own Paradigm Reference series and I'm quite intrigued by your statement (saka hindi ako naging pogi, hehe)
Peace...

LSi9's SQ is a cross between the HF performance of a neighbor's KEF XQ10, Midrange/soundstaging of of a B&W 683 (also listened to this in AVShop), Bass of my old AE Evo1 (without the bottoming out part) and all put in together in a very heavy bookshelf enclosure.
Night and day comparison between my old RTiA3s with imaging, brightness and bass
Why not the RTiA7s or the RTiA9s? = DOGS
Ever since my hubby and I had dogs here at home (and yes they sleep on our feet), the bookshelf format was the logical speakers to choose, less issues / consequences with the dogs urinating / pooping on the speakers in the living room (as compared to a floorstander).
When the new house gets completed then I can go back to floorstanders for the dedicated audio/HT room

Among the 2-channel amps you carry, tube, solid state or hybrid, which models would you recommend, and how much are these?

IMO, B&W 683 is a little better ( 1-2 of 10) than LSi9 but on a higher pricepoint.
LSi9 is a better choice for price/value.

We are comparing very different animals here. They have very different characteristics, and one set is a tower pair while the other is a bookshelf pair.
People would likely polarize towards one end.
-
I agree sir its two different animal (one is a BS and the other an FS)
I am just saying if your only after the output, B&W 683 is better by 1/10 - 2/10 notches.

I honestly think that it's quite a forgiving speaker with partnering gear, as long as you can deliver the current that it needs.
There are a lot of strong integrateds and separates out there to choose from. :)

The LSi series is both 4 ohms and power-specifically current (read: amps) hungry.
It really depends on your integrated/power amp.
If you pair it with a high current integrated/power amp then it will sing very well.
Recommended amps? Rotel, Adcom, Harman/Kardon, Cambridge Audio (7XX or 8XX series), Hafler, Parasound
-
It's actually not as hungry as many would like to think. The phase angles are very benign, while the impedance only dips significantly below 4 ohms between 35 and 75Hz (this is why an amp with less current capacity would stumble to handle the lows).
Despite the relatively low impedance, there are a lot of 8-ohm rated speakers that are harder for an amp to drive (because of very negative phase angles coinciding with low impedance numbers).

thanks sir mikeer...what about denon pma 1500ae, would you think it could suffice the PA LSI15's needs (140watts/4ohms,0.1THD)? or a smaller power like marantz pm7001 (70watt/4ohms, 0.1 %THD . so far these are the only int amp that i have found from the retailers.
would gladly appreciate your reply.

correct me if i am wrong sir.
so if you would explain it in laymen's term, it doesn't necessarily need that amount of power to drive the LSI15? if that would be the case, from your point of view, what do you think the minimum power that can drive them?
-

Yes, it doesn't need as much as many people think. Of course, having a powerful amp increases your dynamic headroom (a very good thing).
The current needs would vary depending on how loud you're planning to play, and what sort of material you listen to. An amp's electrical capability is not just measured by its power rating, so it's hard to set a threshold power spec for suitability.

It may not need as much current as some people think, but it still needs good current (more than most entry level speakers). Amp selection should not be based largely on rated power output.
What amp are you looking at? A 70 watt amp that's capable of delivering a good amount of current and exhibits a low output impedance would likely suit it just fine. On the other hand, a 120 watt amp with poor damping or current capacity may not do the job well.
Look at the amp's power rating at 8 ohms, at 4 ohms, and at 2 ohms (if any). Unless the maker was fibbing, those amps that nearly double their output at halved impedance would typically be high current amplifiers (not counting amps with multiple taps or speaker impedance switches). Check both continuous and dynamic ratings, as the trend nowadays (at least for entry level and mid-level gear) is to boost the dynamic capability of the amp (aka. instantaneous capacity), allowing it to do tougher loads with "musical material" without building a stronger foundation for continuous output (which could translate to a much higher cost for the maker). Remember that quoted power ratings could be measured very differently between makers and product lines (for both continuous and dynamic ratings).
Amps with high damping factor numbers are those that exhibit low output impedance (granted that you are comparing amps that were measured in a similar manner).
How much are you willing to allocate for the amp, btw?
-

That is for now. :D But there are times when we want to listen to dynamic materials at reference levels every now and then. I've been in the same dilemna before. I've got a 3 watt SET drivin my klipsch speakers. Sa acoustic music, ok lang siya. But for orchestra, fast music, the amp starts to clip. That's why i resorted to bi-amping, which solved my problem.

thank you thank you for your patience and time sir. pasensya na din po sa abala. i dont want to double/triple spend to an amp that won't be able to sustain the necessary amount of power for the LSI.
waste of time and waste of money. :(
sir, budget will be in between 15-25thou.

That's a pretty tight budget for a new amp for the LSi15. You may want to check out used high current amps (or NOS units).
Sa new amps, the NAD C375BEE is a very solid integrated amp for its selling price. I'm not a NAD fan, but this is a product from NAD that really gets my attention (it has since its launch over 2 years ago, when I first saw the unit in Spectra). The internals are high-end worthy for a price that's fairly close to the much less robust C355BEE/C356BEE. It's almost like getting the C165BEE and the C275BEE separates together in one package (and at a much lower cost). The 150w x 2 output rating of this amp is very conservative, and it will drive most speakers well with most material (so you'd likely keep it even if your listening preference changes). Bench tests show that it can output 200+wpc @ 8 ohms continuous very cleanly, with the 4 ohm output being significantly higher than that. The dynamic capability with a low impedance load is also great for its price. I personally can't think of a more robust HiFi amp from a major brand at this price range. Check if you can stretch your budget for this amp. :)

Malaki naman ang discount pa diyan. ;) Or pwedeng installment sa card hehehe. At least di ka na magiisip na baka nabibitin speakers mo.
If you want a new amp for 25k, CA 650A ang best bang/buck na alam ko na new at that price range. The Onkyo A5-VL can also deliver quite some current for the price. Kung puro acoustic jazz, vocals, etc. lang ang pineplay mo, chances are kaya na nito.
Of course, better siguro kung may mahanap ka na fresh na used unit na mas capable for the added flexibility.

May old model NAD power amp dati na sale sa Makati. I forgot the name of the store. Distro ng Sony. Old stocks nila. I forgot the price din pero it's double the size (dimensions) of the amp master guru Stagea mentioned. I would pressume masmalakas yun. And IMHO, mukha ngang bagay din ang NAD sa Polk.

Mas mahal kaya yan speaker mo kesa sa C375BEE. Last time I checked 59k ata ang amp nato (if I remember right), ewan ko kung tumaas na. The matching CDP is 37k srp ata.
The 650A is capable of driving 4 ohm loads (I'm not saying that it would be comfortable doing it, though). 115w x 2 at 4 ohms ang continuous rating nya.
If you're willing to head the Class-D route, the Onkyo A-9555 delivers quite some current for the price (though it's low on damping, as with most lower-priced Class-D gear). This amp is only slightly above your target price range, and packs quite some punch. It's rated at 200wpc at 4 ohms ("Japanese Watts"), with a realistic output not so far off (1% THD point is at 175wpc as per Stereophile). Madami tayo Onkyo dealers dito, baka maka-arrange sila ng audition for you. Try mo contact si Marc / AVShop about it. :)
The A-9755 is even more capable for a bit more money, with a 300wpc rating at 4 ohms. The dual-mono internals is quite impressive for its price. See below:
(http://www.big-screen.de/deutsch/image/produktbilder/hifi_sound/elektronik/onkyo/onkyo-a-9755.jpg)
The A-9555 shares most of the A-9755's internals, but gets a single larger tranny, presumably running a lower voltage but with a higher current capacity (which isn't much of a damper, imho). Many of the design-matched CD players like the DX-C390 and the DX-7355 are also reasonably priced.

Yup that's the one. No worry about incompatibility since PDVD makes it easy to trade.

thanks sir mikeer...what about denon pma 1500ae, would you think it could suffice the PA LSI15's needs (140watts/4ohms,0.1THD)? or a smaller power like marantz pm7001 (70watt/4ohms, 0.1 %THD . so far these are the only int amp that i have found from the retailers.
would gladly appreciate your reply.
the PMA 1500AE is a UHC (ultra high current) MOS transistor integrated amp while the Marantz PM7001 is your typical bipolar transistor integrated amp.
The sound characteristics are different - Marantz by experience is fuller sounding than a Denon although Denon PMA UHC MOS models are known to be refined - bass is very articulate.
Why dont you audition the Denon PMA 1500AE and the Marantz PM7001 first before you decide which is which.
We all have different tastes in sound characteristics
-
Yes, it doesn't need as much as many people think. Of course, having a powerful amp increases your dynamic headroom (a very good thing).
The current needs would vary depending on how loud you're planning to play, and what sort of material you listen to. An amp's electrical capability is not just measured by its power rating, so it's hard to set a threshold power spec for suitability.
in addition
amplifer design comes into play here as well
wattage (watts) of the amplifer is one thing, how they are derived to get to that number is another
and we go back to electronics 101 : power (watts) = voltage (volts) x current (amps)
in as much as 100w of amp power can be permuted into several (voltage x current) configurations.
and they all sound different mind you.
Amplifiers that are more voltage over current (more volts than amps) makes the amp sound bright = great treble but at the expense of 'thinner' bass
then there are amps that are more current than voltage (more amps than volts) which makes the amp sound dark - lots of bass at the expense of thinner treble
of course the ideal is a balance between dark and bright characteristics but one factor here is:
1. who is listening?
and
2. who determines what is 'balanced'?
sound engineers 'listen' to their amplifier prototype/design extensively before an amplifier model is mass produced and/or they rehash/recycle an old design (refresh it with new parts) and incorporate it into the new model (which is often the case)
the typical japanese sound is 'clarity' - superb mids and highs, with a 'hint' of bass
the typical american sound is 'in your face' - bass and treble aplenty, so-so mids
the typical european sound is 'controlled' - open midrange, controlled bass and treble
then there are brands (inclusive of DIY) that subscribe to any one of these characteristics.
-=-=-=
one way out of this mess = audition with your existing gear and use your ears before you buy.
tip: take your time in auditioning. it is a tedious process I know but its worth the effort.

It's hard to say more amps than volts (or vice versa), since they are not comparable. You need more current to sustain a higher voltage through the same load. For example, to deliver 100w to a purely resistive 8 ohm load, you need 28.28VRMS and 3.55A. There is no other way to do it. You cannot drive 50V to that load and only pass 2A.
A high current amp could deliver more current before distorting, when compared against a low current amp. A high voltage amp can reach higher output voltages before hitting its internal limits.
Low current amps do not necessarily sound bright, otherwise most tube amps would sound bright. They are designed to drive higher impedance loads, and preferably those that aren't very capacitive.
The problem occurs when these amps are asked to drive more difficult loads. They become current-limited once too much of it is demanded, causing non-linearity (the amp wouldn't reach the desired voltage, and would thus cause gain compression). This modulates the output relative to the speaker's electrical characteristics, so if a speaker introduces a lower impedance at lower frequencies, then the output would likely be bass-light (while a speaker that dips in impedance in the midrange may sound muffled, etc.). This inverse relationship often causes speakers with wild impedance curves to sound very different (often very uneven) when coupled to a low current amp (unfortunately, some people like the resulting sound).
A modern high current (and low voltage) amp on the other hand, may not be the optimal gear for driving very high impedance loads (such as many vintage speakers from over 40 years ago), as it may not produce the voltage required to deliver the desired amount of power to a high impedance load (this can cause audible clipping, or trigger an amp's protection/soft clip circuitry). Fortunately, vintage speakers are often also quite a bit more efficient than their modern counterparts.
Of course many other factors come to play, but these are the very basics.

hence the wisdom behind bringing the amp that one intends to pair with the speaker / amp that will be matched with the speaker at home exactly because of the myriad of factors that come into play - characteristics of the amp, characteristics of the speaker, dynamics/behavior of the amp paired with the speaker at low / medium / high volumes

since this forum is meant for polk audio LSI series i have read in one forum of PA that it's possible to modify the crossovers of some speakers, but i don't know if any owner of PA here would do such to change their x-o's. but as per the member who makes the modification, he say's :
In my experience with center channels you should obtain a cleaner top end and midrange - so ultimately vocals will sound cleaner, clearer. It really depends on how much information you send your center channel - could be dramatic or minor. But crossover upgrades for me have always been positive, large improvements.
is it possible? since i am don't have the technical knowledge of x and y's capacitors blah blah, i will just leave it to you guys to check if it's possible or not..... heres the link :

@defcon
Modifying the passives is possible. It'd surely change the sound --- however, it's always a two-way street. You can improve or degrade the performance.
The LSi speakers already deliver great performance as they are, when matched carefully. I suggest you try your LSi15s with different components first, to find a pairing that will suit your room and your preference (unless you plan on going the processing route).
-
Yup that's the one. No worry about incompatibility since PDVD makes it easy to trade.
We mixed and matched some stuff with your gear last Saturday.
The result: Your Roksan Kandy L3 and your Polk Audio LSi9 sing wonderfully together with the Onkyo CS-5VL set to Filter 3, tied together with Marc's generic speaker cables (the brown ones) and Rey's Monster THX ICs. They just work together to produce a satisfyingly full and urgent sound that never felt lacking in drive or reach. That set is the best I've heard in Marc's place (and I've heard quite a lot of gear in that room) --- it's truly demo-worthy.
Just remember to plug them straight to the wall, or at the very least to a relatively stiff power source. The Roksan pulls enough current that dynamics get squashed and nuances get glossed over when connected to a less able line conditioner or AVR.
Congratulations with this purchase. I'm sure you'd have lots of listening hours ahead.
Rey and James, thanks for inviting me over to play with these components.

in the PA forums specifically the LSi9 crossover mod thread, there are specific mods (with pics) to the LSi9's crossover using different caps / resistors.
The thread starter claims the LSiX drivers are already superior, and are only 'held back' by the 'cheap' quality of the crossover components (pictures of the 'offending' parts are displayed) hence when the crossover is modded, it offered better imaging, frequency response.
source: http://www.polkaudio.com/forums/showthread.php?72273-LSi9-Crossover-Modification-Project (http://www.polkaudio.com/forums/showthread.php?72273-LSi9-Crossover-Modification-Project)
I am open to the concept of modding the crossovers, then again the replacement parts (caps / resistors) should be able to fit the cramped space of the PCB (as you can see in the pic, the LSI9 crossover PCB is paltry) or done outside the speaker cabinet/enclosure.

Thanks Bro. I was actually hoping you'd stop by when James and Rey told me you lived nearby. I noticed too the difference with the brown generic speaker wire. Up until I'd heard it myself, I was skeptical speaker wire could affect sound quality ... or maybe my ears are learning.
My plan is to plug it into the 5KVA AVR. I hope it is stiff enough. Electricity has been pretty well behaved so I suppose plugging it into the wall is also ok.
Is the "Onkyo CS-5VL" correct? Did a google and couldn't find it.

Both Rey and James texted me to stop by when I'm free. I've heard the LSi9 with different amps (and a mix of various gear) before, and it never sounded as right.
Sorry, the hyphen was misplaced. It should be Onkyo C-S5VL.
A 5kVA AVR should be plenty stiff. Of course, you can always compare the performance with and without it.

Mas mahal kaya yan speaker mo kesa sa C375BEE. Last time I checked 59k ata ang amp nato (if I remember right), ewan ko kung tumaas na. The matching CDP is 37k srp ata.
The 650A is capable of driving 4 ohm loads (I'm not saying that it would be comfortable doing it, though). 115w x 2 at 4 ohms ang continuous rating nya.
If you're willing to head the Class-D route, the Onkyo A-9555 delivers quite some current for the price (though it's low on damping, as with most lower-priced Class-D gear). This amp is only slightly above your target price range, and packs quite some punch. It's rated at 200wpc at 4 ohms ("Japanese Watts"), with a realistic output not so far off (1% THD point is at 175wpc as per Stereophile). Madami tayo Onkyo dealers dito, baka maka-arrange sila ng audition for you. Try mo contact si Marc / AVShop about it. :)
The A-9755 is even more capable for a bit more money, with a 300wpc rating at 4 ohms. The dual-mono internals is quite impressive for its price. See below:
(http://www.big-screen.de/deutsch/image/produktbilder/hifi_sound/elektronik/onkyo/onkyo-a-9755.jpg)
The A-9555 shares most of the A-9755's internals, but gets a single larger tranny, presumably running a lower voltage but with a higher current capacity (which isn't much of a damper, imho). Many of the design-matched CD players like the DX-C390 and the DX-7355 are also reasonably priced.

I use mine with a Klipsch RW10, analog inputs from the HK3470 sub out, crossover at 50Hz when I was in pasay.
I tried the same configuration recently here in batangas, but had to lower the crossover to 40Hz since 50Hhz is boomy already.
usually turned on for R&B / Dance / House music or during get-togethers/parties, turned off for other genres and for critical listening at night.

The LSi9 plays quite low for bookshelves, but if you want to extend your system's reach to the limits of audibility, then adding a sub would help. Aside from looking for a sub that plays clean and low, you'd want a unit that allows you to cross low (extra controls like a phase control knob and/or a parametric notch filter can also help).
The DSW MicroPRO series would likely be a great match for your system, if it falls within your target budget.

We have a DSW 660 hooked up to our HT. I plan to share some sources between the HT and audio-only systems, can the sub also be shared? Is this a good idea to begin with? I imagine the settings would have to be different for each.

I make it a point not to "expose" myself to things I can't afford :). But maybe you can tempt me with a raffle ;), or significant discounts ;D.

Sources can be shared. And yes, definitely the sub and the speakers can be shared. Actually, ganito ang current system ko. ;) though sa sub lang ako nag-share. no more selectors and toggle switches. I ask king markcrenz to customize an automatic rca switcher with HT as default source for me. So whever i turn om my stereo, the switcher will automatically choose the stereo as a source for the sub. ;)
-
Thanks bro. I'll keep that in mind. For now though, I'll probably keep the audio-only setup at the office as I'm finding soft chamber music makes me more productive, and smooths out the unavoidable "bumps".
One thing I've noticed is that the LSi9, although it does not reach as deep as the RTi9 (which is quite capable of shaking our windows), seems to have what I'd describe as a very tight bass voice. Which for my tastes, is clearly superior to the RTi A3, but not counting the nearly 300% premium.
-
The problem with sharing a sub is that you would be compromising its placement to ensure that it works well with both systems. Swerte mo na lang if one location and setting sounds great for both. :)
-
Swerte ni Master Nelson! ;)
-
Learned something again :).
Unfortunately, our space does not provide a lot of options for placing the sub. It looks like my best option, when I do bring the audio-only system home, is to use it for content that is not too bass demanding, which actually suites me just fine.
Do you have frequency response curves for the LSi9? Where do you get those anyway?
-
Swerte ni Master Nelson! ;)
Yep. Things get much easier if you can afford to cross that low (and he has a dedicated crossover for the audio system). :)
-
Another thing is that the LPF setting that you set in the sub will affect both your movie and music systems. Setting it to 40Hz for example may work with your music system, but will wipe out a lot of the higher impact LFE information. A dedicated crossover can fix this problem, however (or switching settings everytime you alternate between your systems).

Averaged response throughout +/- 15 deg horizontal and vertical range:
(http://www.soundstagenetwork.com/measurements/polkaudio_lsi9/frequency_listeningwindow.gif)
It's fairly even throughout a +/- 30 degree horizontal listening window and a +/- 15 degree vertical window, with just a mild ripple in the midband that's probably due to a mild cabinet resonance. The same thing happens in the LSi7, but at a lower frequency because the LSi7 has a single bigger cabinet, as compared to the LSi9 that is split up to two chambers inside. This imbues the LSi7 with a darker flavor in the midband, while the LSi9 is closer to neutral. Both units measure very well, for the most part.
A crossover setting of about 60Hz would probably do well in a large and open room. In a smaller area, you may want to use a lower cross point to minimize boominess.

Check out the new Polk Audio Polk Audio LSiM703 at the Dusit hi fi show.
(http://www.polkaudio.com/images/home/medium/cherry/lsim703.jpg)
The New Bookshelf for Serious Listening
With the performance of the groundbreaking LSiM Series in a smaller, more flexible bookshelf-speaker format, the LSiM703 gives you the best of all worlds.
Dynamic Sonic Engine (Driver and Tweeter)
The heart of the new LSiM Series is this incredible enclosure-within-the-enclosure, the Dynamic Sonic Engine, that houses the mid-range driver and the Ring Radiator Tweeter. Molded in one rigid piece, the DSE enclosure tapers to a "turbine" that reduces back-wave reflections. The DSE combines its two speakers in an aligned, optimized array for wide, uniform dispersion in the critical 200Hz-2kHz midrange, improving transient response; the combination delivers exact timbre-matching, improved high-frequency dispersion and greater horizontal off-axis response
Enhanced Ring Radiator Tweeter
This tweeter was a vital element in the success of the original LSi Series. Yet, that wasn't good enough for the engineers designing the new LSiM Series. They've made some nuanced improvements in the design of this tweeter. First, they reshaped the tweeter's bullet-shaped phase plug, allowing it to move farther out of the baffle, improving dispersion and eliminating horn-loading. Next, they opened up the tweeter's face-plate, then redesigned the tweeter's diaphragm roll to make it more efficient and improve dispersion even more. Finally, they gave their new Ring Radiator Tweeter its own tuned enclosure in the exclusive Dynamic Sonic Engine. This new Ring Radiator boasts higher power handling, extended dynamic range, improved dispersion and extended top-end response.
Super Cell Aerated Polypropylene Cone Material
If the perfect cone material is lightweight (for faster, more efficient action) and stiff (for less distortion-causing flex), with enough internal damping to suppress and offset any limitations of its lightweight stiffness, then the Super Cell APP Cone Material is about as perfect as cone material gets. Aerated Polypropylene (APP) is a mineral-filled polypropylene material that's been "puffed up" with injected air to form a honey-comb structure. Our original APP cone approaches the ideal balance of lightweight stiffness with high damping, along with good resistance to moisture, UV and temperature extremes. Next Gen LSiM Series Loudspeakers employ our next gen APP Super Cell. In Super Cell APP, the "puffed cells" are larger, for a thicker cone material that actually has less mass than the original APP material. Super Cell APP has larger cells, for lighter weight and more inherent damping, plus uncompromised stiffness, for unsurpassed transient response and resonance suppression.
Butyl Rubber Surrounds
Durable, soft, injection-molded butyl rubber surrounds are tuned to absorb and suppress unwanted cone resonances. Our new rubber material is impervious to UV, extreme temps and humidity, for a lifetime of smooth, reliable sound.
Extended Linear Motion Voice Coils
Allowing lots of movement in a limited space, ELM Voice Coils power the LSiM mid-range and mid-woofer drivers to extend their higher-frequency response with much less impedance. (LSiM Subwoofers use Overhung Coils, which allow the larger excursions and greater power handling necessary for big subwoofer performance.)
Cast Aluminum Baskets
These lightweight, splayed-strut design baskets provide a rigid structure for precise alignment of the speaker's active parts, for flat response and low distortion, with no mechanical resonances or ringing. The open design provides ample venting for unobstructed linear movement.
Orth Crossovers
Proprietary engineering, designed and patented by Polk Audio to maintain a lower order crossover design and increase power handling. Orth Crossovers feature Mylar and Polypropylene Capacitors for sparkling highs and Air Core Inductors for superior transparency. Notch Filters and sophisticated Zobel circuits smooth the impedance curve of the system for more efficiency and better high frequency response.
The LSiM Enclosure
The enclosure is an integral part of the sound design of the new LSiM Series. All LSiM cabinets are made of .75" MDF, with wide-radius baffles of robust 1.25" MDF. Substantial internal bracing, each driver has its own separate non-parallel chamber, increases efficiency and banishes internal resonances and standing waves, for high power handling and incredible smoothness. Wide-radius baffles, along with zero-diffraction magnetic grilles, help stabilize imaging for a very wide, well-defined soundstage.
Zero-Diffraction Magnetic Grilles
Super thin 1mm, zero-diffraction grilles have no measurable effect on the speaker's response. Completely unobtrusive, stylishly sheer, these grilles lock in place magnetically.
PowerPort Bass Venting
Patented Polk Audio technology that uses a specially designed "cone" at the mouth of the bass port to direct moving air as it exits the port. Air moving out of a bass port creates turbulence, which can result in boomy distortion and "port noise," especially at high volume. This distortion can cause bass output losses up to 3dB, wasting lots of amp power. To eliminate bass-stealing turbulence at the mouth of the port, Polk Audio engineers designed the PowerPort. It's unique shape promotes "laminar" airflow even in short tube ports by mimicking the properties of longer, flared port openings. No turbulence means no wasted power, which means more efficient bass response.

Spent a hour or so playing the LSi9 at about half volume. Wow!
I'm not up to putting into words its performance but I can say that it does out perform the A9 in the regions they share, and the LSi goes pretty low actually. This not to say the A9 is a low performer however for sure if you are 100% music that does not need the 18Hz reach of the A9 then the LSi9 is the way to go without a doubt ... of course IMHO.
Next on the TODO list is to move the monitor on my desk to the other side so it isn't in the way of the speakers :)

My opinion is shifting, the LSi9 are recently sounding "less" than the RTi A9 ... strange. Unfortunately, my schedule has not allowed me much time to tinker.

I'm just curious, the Roksan LIII is already a 'bright' amp despite the lack of tone controls. It doesnt cajole the LSi9s ring radiators to life yet?

Actually what I am using is a MKiii which I think is the predecessor of the L3. Not really sure Bro what you are asking about but better to ask Ivan or the guys at avshop, who helped me choose.

Had a chance to listen to the LSi9 most of the day today, just after spending nearly yesterday with the RTi A9, with more or less the same music.
When it comes to music, IMHO, now, the LSi9 (w/ the Roksan Kandy MKiii) is better, all around, in music than the RTi A9 (w/ a Yamaha RX-V3800 in "Pure Direct" mode). The mids of the LSi9 are clear and the bass and highs are pretty much the same ... for music that is though I've never tried the LSi with a movie.

because of ambo, I got stuck in Batangas and decided to listen to the 9s straight for several days
They're finally bright with the Rotels.

It's about time I updated this thread
After almost 4 years of being with the Polk LSi9, and after several match ups, finally found the perfect sound for it
- Source: Onkyo CS5VL SACD/CD/MP3 Player
- Preamp: Cambridge Audio Azur 650A
- Power Amp: Rotel RB1582
- ICs: QED Audio Pro 2 RCAs
- Speaker Wires: Tsunami Competition AWG12
- Acoustic Absorbers: 4 foam eggshell panels that line the back and centre back of the speakers (Thanks Nelson and MLY!)

Nice! Good to see some systems slowly being perfected through the years, you finally nailed it :)
Yeah, those acoustic absorbers do wonders as long as it is properly designed and applied
