We had a similar problem when we first set our stereo system up in the living room. Turned out in was because the subwoofer was sitting up under a glass and metal table and the bass was causing the glass to rattle in the metal seating. Maybe something like that is what's going on in your case. Might have something to do with where your subwoofer or other speakers are sitting.
