Wiggum Posted October 2, 2001 Share Posted October 2, 2001 Hey all, Take a look at these panels: Color photograph: http://www.rpginc.com/products/abflector/index.htm Overhead plan view: http://www.rpginc.com/products/abflector/abt_4cut.htm According to Everest, by placing these on the sidewalls (and ceiling) between your NFM's and your listening position, you will [b]a)[/b] absorb early reflections, and [b]b)[/b] push any unabsorbed reflections to the rear of the room and away from the listening position. Even with the partial air cavity created by the angled panel, I realize these are strictly for mid/high frequencies. BUT, do you really think the angled surface makes a difference? I made some slick #703 panels, but I haven't mounted them yet, and I have been trying to figure out a way to replicate this angled effect. I've considered foam, wood, and other frames, but it's starting to grow into a large project. And since I rent, any solution must be easy to remove. Since sound behaves like a ray at higher frequencies, do you really think the angle makes a difference? I originally planned to mount my panels on 2" blocks (to increase low frequency absorption), but this whole angle thing has got me thinking. There might be some interesting diffraction effects caused by the angle, but I can't see the science behind pushing the reflections to the rear of the room. Any thoughts? Anyone tried them? P.S. They are quite expensive... Wiggum This message has been edited by Wiggum on 10-02-2001 at 12:32 AM Link to comment Share on other sites More sharing options...

michael c Posted October 3, 2001 Share Posted October 3, 2001 We've got them in our control room: 3 abflectors each on the two side parallel walls and 6 on the ceiling above the mixing console area. With diffusers on the back wall and also some diffusion and 703 panels on the side and front walls it works beautifully. All 4 corners have bass traps as well................. Good luck.

Wiggum Posted October 3, 2001 Author Share Posted October 3, 2001 Michael, Is it worth my time and effort to try to recreate the angle of an Abflector with my #703 panels? I surely can't afford the real thing. Thanks, Wiggum Link to comment Share on other sites More sharing options...
michael c Posted October 3, 2001 Share Posted October 3, 2001 Yes, especially above the console area. A well tuned room is well worth it. But then again, you can only do what you can do. Spend what you can afford, and then get on with your work........ Link to comment Share on other sites More sharing options...
Mark LaCoste Posted October 4, 2001 Share Posted October 4, 2001 Have you seen the ceiling "diffusers" that ASC sells that look like a tube trap cut in half? A friend has two of them in his studio on the ceiling between monitors and listening position. They are arranged in a V shape, each one on the immaginary line between your head and a monitor. These are just rigid fiberglass tubes, cut in half, and with the paper left on underneath the fabric covering. I would use some masonite for the top, bottom, and back (which would attach to the ceiling. In my studio I just use pannels like you've built on the side walls, and a lighter weight version for the ceiling. My guess is that the angles would make an extremely small difference, and only if the whole room is near perfect. -mark Rubber Lizard Studio Link to comment Share on other sites More sharing options...
