Yea...same goes to stock M3300, my ear quite a pain when listen at a loud volume...

I found c3 has a boxy sound on its satellite too.

There are a lot of headroom to mod, not only the electronics circuit part

It is a wood, just a cheap version of wood...compress from wood grain...

Higher end edifier speaker will use MDF wood on all speakers. Budget one only on subwoofer, satelite uses compressed wood grain.

special case

Why it is like Edifier speaker with different manufacturer name....the amplifier back there design were almost the same like edifier too.

I mean that Kurzweil KS40 is like copy of Edifier R series

Seems like their wood speakers are all on MDF ones after searching around....


Found that a lot of the edifier speaker circuits were similar, only difference on volume controlling function and the op-amp, ST4558C and NE5532.
ST4558C sounds like distorted bass and treble, NE5532 however sound not bad, just felt like lack of something.

My ideas:

- Place your satellite speaker that able to reach your ear level.
- Use mono sound and position your satellite to get center position of the sound.
- Place your woofer in between your 2 satellite speaker below your table, face in front.

Then enjoy your music

Agree, but sometimes if there are footrest table then need to change the table, quite headache for some people. Put on table between 2 satellites actually sound much clearer but monitor took away the place and the table will vibrate, need feet to reduce it.

Isn't that one for home hifi floor standing speakers?

1.5m distance too far for pc speakers.

You guys sit so far, no wonder need put to wide distance...
I sit quite close like normal siting in front of pc that range, it was piercing my ear last time but not after mod

Your table are big

C3 lack of bass?
Is your room too big?

Imo C3 bass are too much for me...need to low down...

Maybe you can try face the sub to the wall, put it very close to the wall under your table.

After burned in, Edifier sounds much more detailed than Altec Lansing MX5021 IMO. MX5021 just movie enhancement type

Yea depends on personal taste

Redraw the pin out diagram, for m3300 modding use



so the input ground is yellow colour wire, output ground is the shield. But i saw both ground are linked together in the volume control circuit board.

I discovered i need shielding to clear out the interference. Gonna find a shielded cat6 cable for it, hoping Lowyat plaza got sell it.

Just direct the input cable to the serial port
I didn't try it coz the volume control is so important to me
