We are currently "remodeling" the room which houses our new 75g reef tank. This room also serves double duty as a media/game room. The tank has its own area to avoid any potential harm to the tank by individuals playing other activities. My concern is with the remodel comes a shiny new home theater system. Gone is the small HTIB that I had when initially planned the tank and in its place a shiny new 7.2 speaker system and all the "potential" ;) room rattling sound that one could ask for. While none of the speakers are extremely close to the tank is this something that I should be concerned about. We don't always listen to the system at reference volume however occasionally "when the wifes away the kids shall play" :wow:

I dont know that I would worry about it too much. You would either need a really poorly constructed house or ridiculously large speakers (no such thing) to cause damaging vibration. :D

I agree with Jon. Based on nothing except my gut feeling I probably would not worry about it.
