12" 4ohms yung 15" 8ohms

Ganito nakalagay sa likod ng amplifier AB 4-16ohms A+B 8-16ohms. Dati 6ohms na pinoneer tower type speakers at yung 12" 4ohms speakers ang ginagamit ko ok naman ang sound nila. Parehas na malakas. pero nung bumili nko ng 15" 8ohms speakers para palitan yung tower type na speakers napansin ko lang na hindi na ganoon kalakas yung sound nung 12" na speakers.

Balak kong bumili ng more powerful ampli anu ang dapat kong bilhin? Pwedi po humingi ng sample set up. At kung mag aaadd ako ng subwoofer paano po icoconect yun? Dapat ba yung ampli ay merong separate outlet para sa subs?

A receiver has a tuner. An integrated amp doesn't have a tuner.

No general rule. Subukan mo pareho.

  glad I found this site, M new on this (should I call it a) hobby, and from what I noticed its totally expensive for an average joe like me..

anyway, to cut the story short, I have an existing HTIB (commercialized lang from Panasonic free kasi).. and I want to set up anew one,  an affordable but a decent one kaya lang I need help from the experts like you guys..

1.  a friend of mine is selling an Onkyo HTs5100B for 35K, is this expensive or should I buy separately?
2.  Also, If I buy a Receiver instead, whats the best brand/model at 18-23K level with HDMI na?  pre loved is ok with me, sabi kasi invest daw sa receivers kaya lang yung nakikita ko puro mga 40k up.. ang mahal,,
3.  last, the speakers ba should all be the same brand when you set up your HT, or mix brands are ok?..  any suggestion on a good set up..

Sorry, medyo tagilid yung mga questions ko,. still learning..

35k can get you started with seperates.

2.  Also, If I buy a Receiver instead, whats the best brand/model at 18-23K level with HDMI na?  pre loved is ok with me, sabi kasi invest daw sa receivers kaya lang yung nakikita ko puro mga 40k up.. ang mahal,,

I would say invest in the speakers as they have more to do with the sound than receivers. Anyway, I think 18-23k can get you decent receivers from well known brands here like Yamaha, Denon, Onkyo etc.

3.  last, the speakers ba should all be the same brand when you set up your HT, or mix brands are ok?..  any suggestion on a good set up..

Ideally, they should be same brand and model. Start with the fronts. I suggest bookshelfs sicne you can put these in the rear in case you get floorstanders in the future.

+1 I agree this one 

[boogieman9092000]

hi guys, cant properly fixed (adjust) my amp, do you guys know who can adjust it for me? i am willing to pay the professional fee.. thanks

[rascal101]

Can you please elaborate more on your problem.

[boogieman9092000]

at first, there was no center,  there is no sound at all coming out from all the speaker, tried to check all the functions of the amplifier, its working... I am really not that familiar with the amp, btw, ita a Yamaha... thats why, i am looking for someone, who can do home service.. thanks

Mga sir meron akong ps3 balak ko sana set up yung sounds nya. meron akong speaker na 5.1 with subwoofer nabili ko lang sa quiapo. Pag ginagamit ko yung ps3 yung red and black audio lang nagagamit ko bale 2.1 lang sya. balak ko sana gawing 5.1 yung output ng sound ko. Anung magandang amplifier ang kelangan ko? mas ok ba yung may optical na amplifier kasi yung ps3 may optical naman sya? tnx!

[[r0n1n]]

brad check mo thread ko:

http://www.pinoydvd.com/index.php/topic,118133.0.html

kelangan mo i-output yung audio via hdmi or optical kung gusto mo 5.1. hth

[PjMoZ]

tnx sa reply

[audiojunkie]

IMHO, pwede rin 5.1 ang output kung ang amp mo meron DSP option like Dolby Surround or Dolby Prologic to simulate the surround sound. pero mas maganda pa ring and True Dolby Digital  or DTS via digital connections (Coax, Optical or HDMI )...

Mga sir newbie question. Para saan po ang NAD amplifier? Mas maganda ba ang tunog ng music kapag sa dedicated NAD cd player? Thanks.

[dhoZe]

Need your help masters,
I have some questions regarding connections and SQ.

1. Is there any advantage/disadvantage of using diy amps? I'll be using a 3 channel diy amp for my surrounds/center and an integrated amp for my front speakers. ( I opted this kind of setup because my speakers has different impedance 8 for my fronts and 6 for the others, some one told me that i cannot connect a different impedance on a single Receiver, kindly correct me if I'm wrong)

2. I'll connect my amps to a decent sound card using a 3 3.5mm to RCA jacks, will the length of the jacks affect the Signal coming from my PC or degrade the sound quality? (I think the signal coming from my soundcard will be analog, as for the manual of the soundcard :3 analog pre-outs:)

3. My front's dividing network is broken and a friend of mine put capacitors to make it work, any suggestion where i can get a new dividing network or is it alright to use the capacitors?

4. Is dividing network is the same as crossovers? (sorry for the noobie question)

[Stagea]

1. This is wrong. You can use different impedance speakers on an AV receiver, as long as they are within the acceptable range for it.

Advantages of DIY gear: you can build them to match your exact needs; they are potentially less expensive for a similar level of performance; doing it yourself adds a little bit of personal touch on your system (and generates pride for the owner)
Disadvantages of DIY gear: higher risk of error (some could be quite costly); typically not as refined as manufactured products (limited to off-the-shelf components, no standardized assembly, and less R&D)

2. Yes, the longer the wire, the greater the resistance (therefore, the more losses you'd incur). You're also more prone to EMI as you stretch interconnect lengths. This is why they recommend thicker cables with large conductors and robust shielding for extended runs.

3. A series capacitor will work as a high pass filter. A properly-sized one will prevent the speaker from self-destructing, but may not put out the best sonic output. It's probably best to repair or replace the dividing network.

4. It is a passive crossover.

I'd rather buy an entry level receiver and connect my PC digitally. Some sound cards doesn't have a good DAC. Hence, a not so good SQ. Whereas a most receivers nowadays have very descent DAC for HT. Plus you get the benefit of simplicity in your system, less clutter and proper integration (assuming that you work w/in the parameters of the AV/R). There are also entry level AV/Rs that can accommodate external amplification for your speakers if in case mabitin ka sa amplification ng AV/R.

Just my dos centavos. 

[dhoZe]

Thanks sir Stagea and sir Nelson for the enlightenment 

[dhoZe]

Here is the exact model and picture of my fronts that I'll be using sir

Just my dos centavos. 

Even sound cards with premium DACs generally don't sound very good using the analogue outs because of the noisy environment and power supply inside the PC.

Running separate amps also makes it a hassle to adjust the volume (you have to tweak multiple ones).

Nice vintage speaker sir. Good luck with your project.

Thanks sir Stagea. . .

Mga sir newbie question. Para saan po anger? Mas maganda ba ang tunog ng music kapag sa dedicated NAD cd player? Thanks.

NAD- New Acoustic Dimension    is a brand of amplifiers.  Canadian if I am not mistaken.  If you have the budget  and a lot of cd's,why not?

[edwin]

Mga sir newbie question. Para saan po ang NAD amplifier? Mas maganda ba ang tunog ng music kapag sa dedicated NAD cd player? Thanks.

Playing cd on a Nad CD player is better compared to mid range dvd players. An option to improve the sound of a dvd players is by hooking up an outboard DAC (digital to analog conveter). Every cd or dvd player has a built in DAC but is somehow compromised.

NAD or New Acoustic Design is a british brand. They became famous with their NAD3020 int amp.

mg sirs, bago lang po ako dito....sorry din po kung mali ata napuntahn ko na topic... hingi lang ako ng opinion nyo.... meron po kasi akong harman kardon avr 255 model, rated 50 watts per channel, then my balak po ako bumili ng  speakers ko, tpos nag tanung ako dito sa glorietta SA automatic center nagbebenta din sila ng HK ask ko kung kaya idrive ng ampli. gang 250 WATTS khit daw gang 350WATTS kaya dw.. taMa po ba ito, di ba masisira ampli ko...and planning to buy n rin aq ng center speaker bose VCS 10 ok lng po ba ito... tnx.. sana matulungan nyo ako... nga po pala ang minimum input power ng speaker ko sana na bibilhin eh 30 watts...

[Nelson de Leon]

I wouldn't try their recommendations. Madaling sabihin na kaya and tutunog pero sure yan, madaling uminit ang amp mo lalo na kung for HT considering na above moderate levels tayo makinig. A 100w speaker i think would be enough. Most 100w speakers ay malakas na and very descent sounding.

[joveng1234]

Newbie po. 

Just wanted to ask:
1. Does a 5 channel power amplifier need a 5 channel pre amp to maximize it's potential or pwede na ang 2 channels out ng preamp?
2. Can I use a AVR be used instead of a pre amp to feed signal to a 5 channel power amp?
3. If yes is the answer to no. 2 can HK 460 (7 pairs + sub preouts) and the Denon AVR 1911 (which has 1 pair of preouts) or 2311 (which has 12) be used?

Right now my use is more of HT (60 %) then music (40%) but I want to make sure that if I buy audio gears I can eventually add and add; until I get a full blown audio addictus set up with all the bells and whistles. 

TIA!!!
