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.

The Diffraction Hole Absorber (DHA) panels provide a wider architectural pallette to the acoustician and architect.  These panels are constructed of real wood veneers with a variety of hole patterns, including microperf, for tuning the acoustic needs of a room. 

The DHA is a single hole product while the DHA/T is a T-hole product providing a wider absorption curve while maintaining a smaller, less visible hole in the front of the panel.  Front perforations as small as 2mm are available.
