Keep the room parallel. If you do have a problem later there will be a predictable fix. I can attest that having angles at the ceiling wall junctions will greatly improve your sonics. I have found by accident that a lot of accoustic energy likes to stick on 90 degree angles and rear its ugly sound later. You are welcome to e-mail me for the degree of angle to be used. Based on your dimensions and volume. Tom
Trying to build a near ref. listening room? Help
I am trying to build a near ref. listening room in my new construction basement. I need the most help isolating the ceiling. I am planning on using double wall construction for the interior walls. Dimensions are appx. 14.8'x22'x9'. Also planning on running the heat vent into a side wall inbetween the concrete blocks so not to compromise the ceiling or interior wall integrity. Regarding lighting, will wall sconces hurt. What about electrical outlets? Your help is greatly appreciated. Tim
