Well i was listenin to music (rap) and i had the bass at 80% and volume at 55% on my comp/soundcard with Creative MMS, 90% volume 100% bass on the speakers. The bass was strong enough to make the blinds on my windows rattle. Anyway with it that loud i started to hear some rattling on my sub, and now it seems like certian frequencys make my sub cound like a rattling peice of crap.

On some music the sub is fine and it doesn't rattle (a song with lots of bass) but on some other songs it sounds similiar to if you stuck a peice of paper in a fan or something. Anyway does that mean i blew my sub, because it sounds REALLY bad sometimes.

So you guru's think i should RMA? And if i do i hear they don't carry the Z-560's anymore so what would i get back?
