I have a pretty small room that I want to make into a little theater for myself. The room dimensions are 12 feet long by 10 feet wide by 10 feet high.

I was thinking of going with the epic grandmaster with 500 sub, but Im not sure if that will work. Won't the speakers need room to breath (to sound right), it could be overkill? There is no budget to work on, so money is no factor. All help will be very much appreciated.
