Diffusers are constructed of ⅛” thermoformed fire resistant plastic, and are
molded to a special offset pyramidal shape. The surface is white and lightly
textured, or, fabric can be applied directly to the face forming a full finished
edge with tailored corners. The internal portion can be lined with a 1 ½”
thick layer of glass fiber batt to enhance sound absorption. Fiberglass
diffusers are also available without finish.
