(Pyramidal Shaped Diffusers)

Acc-U-Sound Pyramidal Diffusers are ideal for distributing sound evenly within a room. Diffusers combined with absorption panels help to achieve sound clarity in any given space. These diffusers are lightweight for easy installation. Acc-U-Sound diffusers have been tested according to ASTM-84 Tunnel Test and have a flame spread rating of less than 24 (class “A” or “I”).


  • Pyramidal interactive diffusers are constructed of 1/8” thick rigid molded fiberglass shaped into a pyramid for maximum sound efficiency and quality. Edges have a flat flange to allow for lay-in installation at ceiling grid. Optional 2” thick internal fiberglass available on backside of diffuser.
