I have two of the 12"x48" panels and am still trying access the best placement for them. I can tell you that curiousity go the best of me and I peeled the backing loose to see what was inside and I was very disappointed.
Especially when I looked at the cost. They are basically a Sonex panel 4)2'x2'panels are 75.00 at Audio Advisor. I can only say that the Echo Busters I own will be the last.
I figure I can make wooden frames and buy fabric and have 4)2'x2' panels for about 100.00. As for the performance of the product, yes it makes a difference, but not sure where they best assist the sound.
