I recently ordered (6) 2x4 panels and (2) 2x3-4" panels for my home theater room. Well, I finally got the correct pieces of furniture shipped to me and my panels mounted on the walls. The acoustical improvements to this room are amazing. The bass is slightly improved...but the real improvement involves the reduction in "ringing."

This home theater / listening room has been something I’ve spent years designing. Your panels were the icing on the cake. Thank you so much for providing such an effective and affordable solution.
