Need a bit help on my subwoofer

Hi everyone.

I've just got this Logitech speakers for my computer, but I have a question: Is there a way to turn down (or mute if I have to) the bass that the subwoofer is producing? It seems like that the whole house could hear it (didn't expect that subwoofer to be that powerful). I turn the bass volume nob behind the subwoofer to zero, and it still have the bass get in out of the room. If I turn down the volum on the teskbar on my computer, then I couldn't hear anything. Is there a way or a software that can trun down only the subwoofer and not the other 5 speakers?

Sorry about the Multiposting, I accidently click the post.. button three times, please delete them (or can I delte them)

Did the Logitech come with any software?

Also check Volume Control for Bass settings under Advanced.

None, not even with a manual. Logitech stops shipping manuals those in the box.

I can not find bass under the Properties in Volume control. There is a option called "subwoofer". I clicked the "mute" button under it but it doesn't seem to do anything.

Edited: Actually after I've restarted my computer I went to the advance setting again, and I see the "Bassboot" option. I can drag the thing and the bass volume decresed, but it cannot be muted. So I guess that's the best I can do?

Hm... Maybe If anyone could recommend some easy interface softwares that could encode ac3 in 5.1 easily

Nero can do this. but it costs money so screw that.

you could just do a search on softpedia.com for audio converters or something
