Sound treatment

rocray, I have no sound treatment at all at this time. I sold all the sound panels and equipment and starting over and wanted to try something different. Price is great for me compared to the wall panels and they are close by. Different look and some choice of colors. Will see.

Rhodes, this type of treatment will reduce echo above around 250 Hz and will greatly reduce blare in large public rooms. Use for Hi Fi has to be far more selective or you will do more harm than good. There are many manufacturers of sound absorption panels. It really becomes a matter of what you think looks best. I use cheap architectural foam tiles like these

The first thing you have to do is locate your early reflection points on the front and side walls. Dampen one pair at a time. I usually start with the front wall ones. You find the reflection points using the mirror method.
These tiles are dirt cheap. You can tack them up and move them around to develop a strategy. Then if you want something more decorative you will know what size panels to get and where to put them.

I really like the accent products. The Strata comes in a wide range of color. I will be interested in your feedback.

Thanks Mike, do you think there is any part of the room these could be used or not bother? Room is 19 w x 29 d x 9ft high.
