The wooden frame doesn't actually touch the wall itself, being separated by a foam strip. The black material used to cover the business end of the absorber is of the highest quality, making it very aesthetically pleasing as well as highly efficient.

Room Mode Calcultor This JavaScript calculator will determine the Axial, Tangential and Oblique room modes of regular rectangular shaped rooms with uniform wall construction. Axial room modes involve only a single room dimension, Tangential room modes involve two surfaces and Oblique modes involve three surfaces (acros...
