DSS80 Subwoofer Problem

[diabolo]

I have a problem with my Microsoft Digital Sound System 80. Whenever it hits the bass line the subwoofer have a very annoying vibrating sound. Its not the sound that sound be playing too, but when I push against the "cup" to somewhat muffle it, it plays like it should. Like the "cup" is loose.

Does anybody else have this problem, or any fix to it. I have tired searching google, but to no avail have I found a solution.

It seems you must have something stuck or loose inside the speaker cabinet. If you give it a little shake can you hear something moving inside?

nope, can't find anything loose

Can you see the physical speaker? See if anything is starting to tear on the speaker.
