Just got done building our house, now I'm wanting to get started on my Theatre which will be in the basement which has nothing done to it yet. I have the dimensions of the room framed but that's it. My room is 22x13x9 I am planning to drywall the ceiling in this room so all duct work and wiring for upstairs has been run between the floor joists. The room has no windows and 2 doors, one about 4 feet from the left rear corner and one approx. same distance from the front right. The only concrete wall is the rear wall. It has studs across it though so it will also be drywall. The floor is obviously concrete. I'd like to have 2 rows of seats and a front projection screen. I just have a few basic questions for starting this project. #1 What size picture would be ideal for this size of a room? #2 Are there structural details that would benefit me before finishing the drywall? Such as? #3 Is there a better alternative to wall covering than drywall for sound quality? i.e. dampening foam, carpeted walls Basically I'm pretty new to the architecture of a theatre and really only a novice at theatre A/V setup so any suggestions, comments or ideas are appreciated.
