This is in an unfinished basement.

The subs dimensions are 14 X 9 X 48". The room above is the living room. I will definately use some type of isolation products if we go into the ceiling.

The other option we have is to place it in the cabinet behind the DLP TV. It would be about 4 feet off the ground and fireing up.

Thanks for all your input, I'll let you know how it goes.
