Question about Logitech R-20 Computer Speakers

1 Answer

Subwoofer not working...!

I recently bought a new custom made computer and along with it came the R20 speakers with a subwoofer. The speakers seem to be working pleasingly fine but the subwoofer is not. It is not blowing any air or anything out. I have tampered with the controls in control panel but to my luck, nothing.

Please give me a way to try and fix them.

Re: Subwoofer not working...!

Hello Lujo
There is a lot problems, arise from this particular hardware, you can RMS your product, Subwofer for a change for other if has warranty, or buy another sub, from any Radio Shack or other store. may be the insider split sound board if bad, or fried.
try any other brand like Sound Blaster Speakers. for 2.1 speakers.

No sound from subwoofer

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 !!

I recently installed Windows 7 and my Boston BA745 speakers will not work. I'm looking for driver or other solutions.

1) Try the portable player test. Unplug the speakers from the computer and plug them into the headphone output of a portable-type stereo product. This test should produce sound. If it does the problem is most likely in the soundcard, or in your internal volume settings. You should contact your computer's support group for further help in those areas.

2) Is the green power light illuminated? If not, you could have one of two possible causes. The first and less serious issue is that the power supply is not outputting the correct voltage. You can test the power supply with a voltage meter or you can always take the power supply to any electronics store and have it checked there. If it is not outputting the correct voltage (12VAC), contact our parts department for a new one at (978) 538-5136.

If the power supply is working properly, then your problem is most likely in the amplifier. In this case, we will need to fix your system here, and you can contact customer service at the above phone number to set this up.

3) If the system is connected properly and you have a green subwoofer light, disconnect the power supply from the wall for 10 minutes. This is a common problem on overloaded surge protectors. To many devices on the same surge protector can limit available power. Putting your speaker system on its own circuit (or a more dedicated one) should eliminate this problem.

4) Check the bass level on the back of your subwoofer, (or on your desktop control pod. For best subwoofer performance place the woofer on the floor along a wall or better still in a corner. This "corner loading" will increase bass output.

I bought logitec speakers but withought subwoofer is there any way i can connect them to the pc withough the subwoofer or no?

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).....

My Ada 880 speakers work fine, but the subwoofer isnt making any doesnt seem like its getting power but if the speakers work id assume the fuse is good right? i cant seem to find alot of...

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 :)

Audio control pod seems dead

You can see about getting a new control pod from ebay or craigslist but the problem is more likely inside the subwoofer. Below I have pasted a link to a forum thread about fixing the Gigaworks S750 systems. There is not much information there about control pod problems but at least the people on the thread will help as much as they can. If you are not familiar with electronics then some of the people on the forum thread can help if you are willing to ship the subwoofer box to them.

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