2-D PRD Diffuser Design

Hello Everyone, I am planning on building 4 2-D PRD Diffusers for my studio. I will mount one in the back of the control room, 2 in the drum booth in vertical position (on the sides behind the drumkit) and one in the amp room. The designs are based on the Oliver Prime's calculator. I still don't understand the use of different primitive root sequences. Based on what I have read I will use primitive root 7. Studs will be 2x2. I want to be sure the design will work. If anyone can give their opinion/advice on the design and/or the diffuser positioning would be great! Here is the design, you just have to press calculate. http://www.oliverprime.com/prd.php?C=34 ... LT=0&P=571 Thanks in advance and Cheers! Raffaele

What is giving you the impression that you have room dimensions large enough to support diffusion...the room dimensions that you should have included but think that we can guess at ;) It is in the stickies should you care to read them. Brien
