I have app a 14x15 room for my theater..... how does this sound.... Insulate the walls, (tight packed or loose packed) 5/8" plywood, resiliant channel, 5/8 gyproc, for wall construction. Im thinking no subfloor. Carpet on floor and half the wall, then 2 difusers made from 2 x 4 each side of the window and same on the ohter....and 4 wall sconces for the lighting....grey for the ceiling....black curtians for the front with screen. Small stage to place speakers and sub..... Discrete power source for components...8 guage wire from the pannel. the rest on anohter circut. ANYTHING I SHOULD DO differently or upgrade on?
