Hello!

For some reason, I get too much bass or too little even though I haven't touched the computer's volume mixer (Creative Sound Blaster Audigy 2 ZS) and speaker volume controls. 

With very little bass, I noticed if I turn my subwoofer from its lowest setting a little higher, then I feel a lot of bass for a second. Does the speaker have limit controller or something? I checked the cables behind the subwoofer, and they seems fine.

I wonder if my old speaker set is dying (time for a new speaker set). I have had it since December 1999. Has anyone had this problem before? If so, then how did you fix it?

Thank you in advance. :)
