All right, here's what happened guys, I have the NSP1 package, and two sony sa-wm40s in my 15x18 living room. I've had them for close to 4 months, and haven't had any problems until now. The ceiling above my living room is dry wall, and there are 6 wooden planks that are laid out horizantally, covering only 20% of the dry wall. I just got up and I see that from one of the wooden planks, there are two holes that are dripping water. Also, water flows from across that location when taking a shower upstairs. I just want to know if it seems that my subwoofers have caused this. I usually put it up to reference level, like three times a week for around four hours for music, video games, and home theater. I put the subs to a moderate level, one that I can listen to for long durations of time without any discomfort. I'm really in denial because I don't want to loose my home theater, and the plumbing is going to cost me a fortune! Any advice would be appreciated.
