You know Mel, all the technical discussions were very good. But since I can't digest it, I stick with my ears to test what you said. After all the experiments that we did, most of them esp.the last one we did was very successful and I am proud and confident to share it with other audio gears for comparison. Thanks bro.

You're welcome Bro

Bro, we are adding one small improvement at a time so that in the overall picture we have a big improvement.

BTW, by playing around the tweaks introduced earlier ... instead of the snubber circuit, the small choke that we have introduced earlier can be used. So, after the amplifier we have a 6turn choke in series with the +speaker wire going to your n (1, 2 or 3) way speaker.

The advantage in using this approach is that we have a faster rate of charging/discharging current. The disadvantage is that the small choke creates a high impedance at high frequency. Also, would this choke (100nH) be of concern with regards to amplifier stability? I don't think it is a big deal as 6turns is only 60milliohms at 100KHz. Further, it should have little impact on phase margin. So, it is a matter of weight ... no small choke or with small choke ... which sounds better? Try to find out

I've done that. It was so musical with my car audio set up stock Targa speakers.

Wow! Once I have time will definitely create another one. More power to you Bro!
Bro Rascal thank you for sharing your talent!

It just turned out that I had some time to do experiments. And, had a willing victim to do the experiments with

thank you for the info sir rascal101! i already tweaked my speakers, it really gives cleaner highs now. also did some tweaks on the port of my speakers, extended the port by using a (used) pvc pipe. so it now gives a better low frequency extension. overall, im so happy with my small and old but reliable pioneer micro component.

Sir Shrek7,

Ang kapal tumunog at ang linis ng highs

Some pictures to illustrate the 6 turn choke tweak ...

Like this ...

Or, like this ...

Anyone would do.

Sir yang 6 choke turn lng outside the speaker may magbabago na sa SQ?

rascal101 · « **Reply #129 on:** Oct 27, 2010 at 08:42 AM »

Opo Sir. Mas maganda kung makagawa kayo at i-test para ma-check ng husto

wengkapre · « **Reply #130 on:** Oct 27, 2010 at 08:51 AM »

Sir yan lang talaga? kahit wala pa akong snubber? Ano po diameter nung pencil & thickness ng copper wire?

rascal101 · « **Reply #131 on:** Oct 27, 2010 at 04:32 PM »

Opo Sir. Ganito po set-up ng tv at mini component ko sa bahay.

Ang diameter ng pencil na gamit ko ay 8mm at ang wire gauge ay #18.

marvin13 · « **Reply #132 on:** Oct 27, 2010 at 05:07 PM »

sir mel ok n...ngawa ko n din sa front and center speaker ko n pang HT ngyon lng

kaso mukhang mhirap nga pag AWG #12 speaker wire ang gamit, hrap twist.

rascal101 · « **Reply #133 on:** Oct 27, 2010 at 06:02 PM »

Oo. Kaya AWG #18 lang gamit ko.

Kung gusto mo makapal mag bifilar wind ka. Dalawang AWG #18 na sabay mo i-wind.

Sir rascal, just made it kaninang hapon, I think my ears says na may improvement sa mids & highs, parang naging thick yung boses? warm ba tawag dun Sir?

rascal101 · « **Reply #135 on:** Oct 27, 2010 at 07:41 PM »

Bro Wengkapre,

Hindi ko sure kung ano ibig sabihin ng "warm" na term sa audio dahil hindi ko ginagamit. Pero tama ka ang epekto noong tweak ay sa mid at highs at mas makapal na boses.

jtahanlangit · « **Reply #136 on:** Oct 27, 2010 at 08:58 PM »

Tried this tweak before I left home for a month long work and now I missed the improved sound of my speakers again..Bro Rascal101 is a great help for a very noticeable improvement on my speakers..Bay mel, I can play with my speakers again when I get home next week..

rascal101 · « **Reply #137 on:** Oct 28, 2010 at 04:16 AM »

Bro Kirkshy,

Replied to your PM. Have made some suggestions you can play around with

jtahanlangit · « **Reply #138 on:** Oct 28, 2010 at 05:33 AM »

Sigurado busy na naman ako nito Sir Mel pagbakasyun ko dahil sa update na ibinigay mo. Busy sa kakalikot ng speakers..

rascal101 · « **Reply #139 on:** Oct 28, 2010 at 06:08 AM »

Maraming ideya na puwede i-try sa speakers ... depende na lang sa atin kung bibigyan natin ng sapat o tamang panahon ...

Nice! Sir Mel this is what I really wanted to hear from my speakers, yung tipong nasa harapan ko lang yung singer at musicians playing their instruments

Ang hirap palang bumili ng tinging magnet wire? Sinabi ko na lng pwede 2m lang po kasi gagamitin ko sa project

pinagbigyan naman po ako Sir Mel.
pag nagawi ako ng RAON, will buy the parts and try the snubber naman

Thanks for the tips Sir Mel

sir mel newbie lang po

pede po ba yan sa 6 inch na woofer or 4.. para po makalikot ko na tong speaker ko na nakakainis na tunog..

TIA!!!

rascal101 · « **Reply #142 on:** Oct 29, 2010 at 12:46 PM »

Personally po na-test ko itong mga tweaks na sinabi ko rito sa hanggang 8" na woofer.

sir mel.! i currently reading ur thread.. nanginginig na mga kamay ko, i cant wait to tweak those irritated speaker that i have!..

rascal101 · « **Reply #147 on:** Oct 29, 2010 at 01:57 PM »

Sa akin pong pagmamasid isa sa sikreto para gumanda tunog ng speaker ay mabilis at controlled na pag-charge at discharge ng kuryente. Kung kaya't mahalaga na maintindihan ang mga choke/inductor at capacitor ng lubusan.

Pecs · « **Reply #148 on:** Oct 29, 2010 at 07:37 PM »

sir mel ginamit ko r1,c3 sa warfedale bat ang hina ng tunog

rascal101 · « **Reply #149 on:** Oct 30, 2010 at 03:39 AM »

Sir qazwsxedc,

Iyung R1, C3 ay snubber po. Mahina po talaga ang tunog niyan. Ginagamit ito na nakaparallel sa C1, C2 or doon sa tweeter coupling capacitor para pang limit ang high frequency peak voltage (para hindi sobrang kalansing at ma-sibilant).

Salamat po
