Question about JBL Simply Cinema Satellite Speaker (Each)

Open Question

Older JBL System

I recently moved and my 10 year old JBL Sumply Cinema powered subwoofer wont work now. There is no way to access it beyond the remote which is also not working. It worked before I moved it and it hasnt been dropped. I can hear bass through it but it sounds muted. I dont know what to do. Its a great stereo but maybe its time to upgrade.....

SOURCE: connection a JBL surround cinema speakers with sub to a Yamaha

if you do not have the digital hook up from the tv to the reciever
304c659.gif then you will not get the subwoofer sounds or the dolby digital sounds
if you don't have this on your tv then just turn off the dolby digital when watching the tv , and you should be able to hear the subwoofer thru the virtual surround sound
hope this info is worth a fixya and if you need other help then just ask me and
i'll be glad to help

SOURCE: Subwoofer Bass Level Problems

What is your sub stood on? If it is on a piece of furniture then this could be the problem. Bass frequencies travel further than higher frequencies due to their longer wavelength and will also be transmitted through any solid objects the speaker is in contact with. The solution is to mount your sub on a piece of foam to provide some damping.

Also if your sub has a port (a hole) on the back or side this needs to have a good 3 or 4 inches clearance from nearby walls or panels.

Finally the speaker cone itself needs to have a clear path to push sound energy into the room, if this path is blocked by furniture (some people like to hide them under tables) then it may make that furniture vibrate.

Winslow is correct. It is likely to be a bad capacitor on the power supply. There should be two large capacitors on the power supply circuit. These capacitors filter the 60Hz waveform from the power. These will be the two largest capacitors in the entire system. The bad capacitor is probably bulging. For safety, you should replace both capacitors with exactly the same uF, voltage, and temperature ratings. Don't use anything smaller than the ratings of the current capacitors. And don't waste your time going to RadioShack, they won't have any big enough capacitors. It would also be a good idea to check any resistors that are near the capacitors, if you see a slightly larger resistor that is burnt, then you will probably want to replace it.

SOURCE: JBL Pro Computer Speakers....


I believe your old sound card may be of higher quality than your new one, I had the same problem years ago what I did was this, I ran my speakers through an old dedicated dubbing cassette player out of an old kenwood stack stereo then into the computer, the cassette has a mild adjustable preamp when in record, you will have to put the deck on record the rest of the time with a blank tape- any old cassete deck will work.(thrift store) and your going to need a couple parts from radio shack. If you have the know how I suggest switching the audio cards out, drivers etc and / or seeing if you can have them both plugged in without an issue. If issue then try cassette then call and complain to the computer company for installing sub standard equipment.

computer audio output-> line in cassette->line out cassette-> line to speaker input

good luck
