Hi all, hoping to gather some knowledge from those with far more than I! I recently bought a home with a large(21'x13'6"x9'6")game room that is going to be my new theater. I am mounting a high def front projector in my ceiling, putting in 2 rows of theater recliners with bass modules and amplifier, and just bought a Yamaha RX-v1800 7.1 receiver. My big concerns are if the current in ceiling speakers are going to work well in a theater or if I need to do something different. Also, can anyone recommend a sub for the system as well? Any help would be appreciated as this is the first time I'm setting up a system that didn't come out of a box.
