Popular Post MarkusBarkus Posted October 18, 2020 Popular Post Share Posted October 18, 2020 @HI FI I have tried, and still have, many different treatments in my room. Perhaps 25 or so. I have mixed velocity based devices with pressure based treatments. I have a difficult room, that now sounds very good. I agree with @ASRMichael that GIK site has a lot of info; however, while generally true, using diffusion for first reflection might be different in your room. Also, many diffusors are really "reflectors" that just bounce the sound around. That's OK too, but it depends on your room. Regarding your actual question, I have GIK 3D diffusor/absorbers at first reflection points (walls) and absorption on the ceiling first reflection (two inch panels, four inches off the ceiling). Floor is a padded area rug. In my opinion, the only "true" diffusion I have here is a set of quad diffusors on the back wall, built from plans purchased from Acoustic Fields. They were complicated builds, but very good. ASRMichael and Kyhl 1 1 I'm MarkusBarkus and I approve this post. Link to comment
