it shows that the edifier responds deep bass better compared to logitech
logitech filters too high up oredi... while edifier can take some abuse from deep bass

Erm, I tot crossover use non polarised cap.. thats why dont need worry which side is positive or which side is negative?

Hey guys, does speaker need to charge ? I find out a weird thing of my M3400, For a cold start, the speaker sounds so weak, but after 10 minutes of blasting, the sound will turns better and louder. Something wrong with it ? 

if i want to replace my power filter caps with better brand, should i use bigger capacity (uF) with same V or same uF same V?

Do some resistor mod experiment for whole day, didn't fully change all but 98% was changed.

Before:


After:


Results is much fine, detail and more balanced. Don't want say so much BS audiophile word liao... 

Its like NE5532 chip made by JRC and Texas Intruments. I still finding whether i switch it to ST one will be better or not.
The resistors are not wasting, it does big improvement to me.

Not all multimedia speaker cannot reach audiophile grade even mod. Believe it has potential....like Edifier speakers. 

lol, it sounded slight different only in the end.
If change speaker than not m3300 liao lor....

I had done my mod, still feel it needs a little more tuning for before i made a stop.

haha.. bro beggarmaster2000, don't like dat le, make me feel very very shame la 

Erm guys, i have a dumb question here, i mean it,

I just operate my old usb powered speaker, Edifier 1250, guess what? even the under rm 50 edifier speaker unit look awesome, its dosent look like any generic speaker at all,
Ok back to topic, what confusing me now is the amp IC that used in the speaker, its D2822, there 2 of em, the question is from the datasheet, those IC is stereo amp, why need to use 2 of em?

I cant pull the pcb out, soo cant trace the schematic how the IC is connected.. kinda curious rite now..

i did some experiment with those amp too, it could power up my C3 satellite and could drive it at the same volume as C3 amp, all from usb power,
Perhaps because both speaker is 4ohm?
but dont expect the sound quality lar..

i do some stupid stuff today.. sigh... i hope my speaker will be ok.. worried about any degrading in sound quality hehe...
