Wall panels to control brightness

I have also been looking at control for brightness.. This looked like it might help. Have not yet tried them out ..

Has anyone tried this product?

Look at rpginc.com. They have a bewildering array of stuff - you could spend awhile reading on their site. You can pick up ProFoam and Skyline at Audio Adviser.

Take a look at Sonex. They are 2 x 4 foot sections. They do a wonderful job. You can order a set of 6. Don't remember the price, but it is reasonable. Stick with the charcoal.
You can get them through Audio Advisor.

www.acousticalsolutions.com carries Sonex, RPG, and others.

If you can get Owens Corning 703 fiber boards they work as well and in many cases better than many of the products mentioned. Take the fiber board and cover it in a loosely woven cloth and hange it where needed (generally at the first reflection points and sometimes behind the speakers depending on their type). This also looks considerably better than the Sonex or RPG solutions.
