Well, (sits back) my parents are accusing me of cracking one of the tiles in our kitchen. I've got the PB2+ close to the wall next to my bed in a 16x16 room. IT's 3ft away from the other wall but there's a closet there...so it's not exactly in a corner. My room is directly over the kitchen and the subwoofer is over the kitchen table. The crack is 15ft away from the kitchen table. I told them that i didnt think it was possible and that if it was i dont think i was ever playing it loud enough for it to do that. So i was wondering if the subsonic destruction crew could fill me in if i probably did this or not and if the PB2+ is capable of doing it if it wanted to. Being on the floor under the subwoofer is worse then being on the floor with the subwoofer!
