Yes, you have to be careful pulling out the back module as the speaker wire to the PCB is very short and risk ripping it off the woofer. I've said earlier, I didn't take many pictures so I'm unable to show exactly how to remove the panel. If I remember, there was some difficulty because they put some epoxy adhesive onto the connectors. I reckon these measures are to prevent tampering and repair. Spoilt?..throw away buy new one!.

The sponge (as seen in shop) comes in some colors, 1" thick and about 18" x 20 something inches...unsure what its actual purposes at a DIY hardware shop in Taipan USJ. I've seen some at tailoring supplies shop but its too thin.

About 3 months ago, my VS4121 developed a problem....

I get microphonic effects when I touch the cables. The effect mainly comes from the cable that connect the sub module to the stereo speakers. Any ideas how I can solve this problem? I am guessing a rounding point probably came loose.

ps-by microphonic effect, I mean: when I touch or cause the cable to rub, I get an amplified "rubbing" sound coming out from the speakers too.... weird?

Jason, since you're handy in DIY, you can remove the amplifier module and inspect it closely if there's any broken or dry solder joints at those connector areas. There's 2 modules inside, namely the amplifier board fastened by 4 screws and the PSU transformer assembly above it also fastened by 4 screws. The manufacturer has used some epoxy glue to fasten up some cables and areas for obvious reasons. You may have to use some ingenuity here for removal and its of course not impossible.

Here's a pic of the main modules.

bloody hell.. the 4121 suppose to come with the Y-Adapter but there isn't any in it.. Ban Leong says we're suppose to buy it ourselves.. bloody con job if you ask me.

Hi guys...
can help on this VS4121...how you dismantled the subwoofer taiko. can help me?
I have problem to switch on my 4121...why is it ya..i bought it about 4years++ already..

hmm, it is true that vs4121 black edition is the newer version of vs4121??
and the newer is the cutcost version?
the first time I bought these I'm kinda dissapointed, it just doesn't sound like what in the review.
I even thought that it's fake speakers or something like that..
mx5021 have dropped its price from 210$ to 170$ also!
but some tells its a cutcost version too..
ahh, is that for real or just a bad business campaign from the competitors??

oh.. and in previous post some say they found vs4121 in yellow LED?
vs4121 with yellow LED is never exist! except if thats some kind of modification though--

looks like green

ohh, sorry for the misinformation..
according to the video on the youtube (that nismo tells us)
the earlier(first time) vs4121 are using green LED. .
then it changes to blue.
at the 70th anniversary of AL, they create the black edition with red light..
also heard that the earlier version(with green LED) are better.
the new ones are cutcost product.. but I just heard it somewhere, not a fact yet..

real Altecs use BLUE
after some time, they change to green(yellow) then new black body with red LED.
i saw many blue lite VS4121 still running fine in old-skool cyber cafe near my home
