Absorption Diffusion confusion reins in many of the comments. You don't tame reflections by using diffusion, you just scatter it around. Mattzack comments that with one side of the room open, reflections disappear on that side. So, his goal is to 'open' the other side. That can only be done by using total absorption. The little absorption that diffusers do is not enough to tame the problem. All the firms mentioned make good products, but some are better values and have higher SAF. DIY always gets into trouble with the SAF. So, first ask each of the vendors exactly what the NRC coefficient of their absorbers are. You will be surprised how many will not tell you, claiming it is not a fair measure since it only tells you what is being measured below 2K hertz. Still, it is a starting point.
Need advice on acoustic panels.
I have had a few Agonners over to listen to my system and the only criticism that has been offered was to add an acoustic panel on the right side of my system.
The left side is completely open and has no reflection issues. On the right side, I seem to be vulnerable to some reflection off of an adjacent wall. He explained how to use a mirror to determine placement of the panel, so I believe that I should be able to contain this reflection with the installation of a 2 foot by 4 foot acoustic panel.
Does anyone have any recommendations for a good supplier of acoustical panels?
