Subwoofer not working...!

If your subwoofer does not work on your altec lansing speakers,
more than likely you blew the subwoofer amplifier board.
I have an ADA-885 system and bought it brand new back in
November 2000 and has been flawlessly operating great up
until this past month when my subwoofer went out but my
"satellite" speakers kept working. After disassembling the
subwoofer box I first noticed that the subwoofer amplifier
board is seperate from the rest of the grouped boards for
the dolby and satellite speakers. The subwoofer box is
designed to use the air from the subwoofer to actually
cool the amplifier boards inside the unit, great feature
until your subwoofer goes out, that is when your main
amp will more than likely fail soon after the sub amp
fails, as it uses the air from the subwoofer to keep the
amps cool. I know this might be an older post but
hopefully I can put it in the right category to hopefully
be able to help someone out in the future.

You can test the ohms of the speaker with a multi
tester. It's a dual voice coil speaker, 6 ohms each.

Well my system is broke and needs another
subwoofer amplifier board so if anybody reads
this and has this subwoofer, I need my sub amp
fixed ! or if you have the subwoofer unit maybe
and nothing else to go with it but the subwoofer
lights up, give me a jingle, I'd buy it from you !!

the speaker with the subwoofer may not work as the speaker needs a power supply to boost the sound from the PC.....even if you connect to the sound jack of PC using some adaptor it may not give out the required sound.....i mean it will need amplifyer, the job of the amplifyer is normaly done by the big box that comes along with the speakers (called subwoofer).....

Hi there bud , There could be a number of problems as it is a refurbished Speaker Set ,It could be The Subwoofer yes , Have you tried it on other PC's? if it does the same then it is The SPeakers that are faulty :(
Hope this helps
Happy new year :)

Hi there bud, this could also mean that something in the Subwoofer has blown or shorted, the best thing to do is too take it back too the shop where you bought it and ask them too replace it .its not worth opening it up yourself and losing the warranty...
Happy new year . Hope you come right :)

chik power sours first
thaen chik transformer inside
u will see it burned if so chang it

did you fix it? I have exactly the same problem, I'd appreciate any help please

if you bought the computer at a retail place like microcenter take it there and they will help installation. if you got a computer with speakers and a sub woofer; then you plug your speakers into the subwoofer and the subwoofer to your sound card mark with the same color as the plug or the symbol marked speaker or line out.

There must be a control on subwoofer, like a volume control. Turn it and check it. Also check the connections.

how are you connecting the sub to you amplifier?

Its due to the damaged pin in which you r inserting the subwoofer pin!
