I'm the proud owner of the Logitech Z 5500 speaker. I noticed that I wasn't getting any lows from the sub so I ran the 'TEST' button on the remote only to realize their was no output from the sub - all other speakers working! Any help? Much Thanks, Joel

Try pulling the power from the unit for a few minutes, the reconnect. Make sure you've got the surround settings correct. If that doesn't do it, you've likely popped the amp or the amp's power supply in the sub box.

i have this same problem, i dno what the heck happend to my speakers. i tries changing the fuse in the plug, and also the timer fuse in the sub itself... stil no fix... im still getting no power to any of the units... the standby light doesnt even come on.

try buying a new optical cable or change some settings on your tv.

.I openened the sound touch control.My logitech subwoofer doesn t work,but all other repros do

You may have blown the speaker and need to replace it. Try at a low volume and then at high to notice any difference, if the popping occurs only at higher volume then it needs replacing. I hope this helps

There are four screws visible that have to be taken out of the plastic. There are also six or eight screws under the screen cover. You have to drill holes in the screen and unscrew the sub. The plastic holding the screen is screwed down underneath the sub.

I use the HT-391 in my home office video studio not sold anymore but it handles 3 PCs giving them 140w of power, plus 6" active power sub has excellent bass. The wireless remote can be programmed with Radio Shack 8-in-one LCD Universal Remote.
the HT-3917 is small but don't let the size fool you. It has 100w of power still not bad for small places.

For what you need to control you're better off getting the Z-5500.

Try to click the EFFECT BUTTON a few times to change the effect settings (see also in display) from e.g. Stereo (which uses only two front speakers) to other settings (for which some will use the other (rear/center/sub)speakers as well). Success,

Dennis

First things first:
1) you can buy on audio stores, boxes for 10 inch speakers
then you can do this kind of work,
I try to do what you did, and you know what happend! *&^%$

Hello Thimo
First things First:
1) The only thing sincerely you have to do in this cases, if you yet have warranty, is RMS the speakers, for a new one, or repair.
other than this, is a internal board power for your speakers.
good luck
