Auralex 2" SonoFlat Panel (Purple) - 16 Pieces

An effective product

I listen to two channel stereo and am using this product to effectively reduce flutter echo and excessive sound reflections off walls and ceiling. I have noticed a great deal of improvement in various ways in the music reproduction in my dedicated listening room. I listened to some recorded music after installing every 4 to 6 panels on the walls and noticed subtle improvements after each group was installed. Though my room is only about 50% treated the improvement is quite stunning. I have ordered another package of these panels to complete the room. If you have an interest in acoustical control and are considering these products do yourself a favor and work with this company. Fill out their questionnaire and submit a sketch of your space. They were very helpful in getting me started. You can go with their suggestion for placement of the panels, but you can also listen to the effect of the panels and make some adjustments. These panels can be installed temporarily, I did so with T pins and some stiff paper around the edges. This way you will not penetrate or deform the product before final installation. Since, I am going to paint the room I am not concerned about pinholes. Your needs may be different.
