The Diffraction Slot Absorber (DSA) panel represents the finest architectural wood absorber of its type available. Utilizing the tried and true Helmholtz principle, the DSA panel offers a unique architectural look while providing excellent absorptive qualities to control sound reflections in rooms.

The standard 14/2 DSA panel features 2mm slots with 12mm spaces in between and several different hole configurations in the rear of the panel dependent on the acoustical properties desired.
