Okay so once i can post some pics i hope to show the room better. The room is about 24 x 12 with 8 ft ceilings. I was going to go with grey walls and carpet with a dark grey ceiling and black wall behind the screen. I wanted to go as big as i can with the screen without getting eye strain ect, I know alot of that depends on the person. I bought 5 klipsch in wall speakers off CL for a really good price and have a decent sub already. I was going to do a diy AT screen.
