Subwoofer problem

By bldsm ·
After checking the other Q & A here I am. I have a HO PC with top of the line Dell 5650 5.1 surround sound speakers. I have a 2.1 to 5.1 channel adapter (works the same as a soundcard but better which clearly allows the PC to play to 5.1 channels. The subwoofer however is quiet and I cannot hear music coming from it just a low rumble. I understand what subwoofers are supposed to do but its' not doing it.

There are no controls on the back and everything is plugged in properly. The control on the front of the subwoofer is correctly set. The driver is the current one too.

Any ideas please?

Thanks
bruce

Subwolfers generally are only responsive in certain frequency ranges, normally 5-50 HZ. That "rumble" are those frequencies.

It might be a bad amplifier for the sub woofer itself.

Could even be a bad driver.

Check your mixer settings, and make sure that the low frequencies are not filtered out.

Also check your sound settings to verify that you are in 5.1 mode with a surround sound speaker setup selected.

Then, play some music that has a lot of deep base and see what you get.

If you still have problems, check to see if the speaker system has a 3 conductor plug that you could plug into a Walkman style CD player and see if you get any base that way.

If you do not get any base from a direct connection, it would point to a problem with the speaker system itself.

Download and run the Speaker Test (spkr-tst.exe) at this link:
http://support.dell.com/support/downloads/format.aspx?releaseid=r19839&c=us&l=en&s=dhs&cs=19

It's intended to check speaker systems that include Sub-woofers.

If it fails the test, speakers should be replaced.

If it pass the test, you'll have to check your sound card.

Test the speakers on another system as well. If it works, it should be the sound card/PC.

Another posible problem is that the subwoofer has an polarised filter inside and you have the connections reversed. Change polarity and see if works.

Don't know what a "HO" PC is, but it sounds like your 2.1 to 5.1 channel adapter is receiving a 2.0 input. My guess is that your sound card just doesn't send anything to the sub-bass channel, and your upmixing adapter is not re-mapping bass frequencies from those two channels to your subwoofer's channel, just turning the two stereo channels into five and passing along whatever it finds on the .1 channel, in this case only transient noise. If you're lucky, your adapter will have a setting for standard stereo input, too.

"HO" is home office, right? If so, it is even more likely that your sound card just will not even output 2.1, but rather only offers 2.0, aka old-fashioned stereo sound. Recommend a low-end Creative Sound Blaster card as the cheapest way to play music or games on 5 satellite speakers and a subwoofer.
