Anybody know of any inherent problems with a home theatre in a dome? Accoustics, sound problems? It is still in the planning stage, but will incorporate a pool table, bar, and theatre. Probably along the lines of 26 to 28 foot diameter by 12 tall. It is concrete so will I have to use some sort of sound deadening to prevent sound from bouncing around. As you can tell I'm new to all this, but after reading this board for a while am greatly excited about it. Any and all commments appreciated. Will probably be going with a Sony 400q for now. We all know how the "upgrade" bug goes though. Thanks in advance.
