Diffusers improve the sound in a room by absorbing unwanted sounds and reflecting the remaining sounds. The end result is a listening environment that is ideal for instrumental performances or any type of presentation where slight reverberation is complimentary to the overall sound. Both barrel and pyramidal diffusers are available in a number of sizes. MBI Diffusers are constructed of thermoformed fire resistant plastic that is molded into either a barrel shape or an offset pyramidal shape. Crisp, finished edges and corners can be achieved by applying fabric directly to the face. MBI Diffusers are available in a textured white gel coat surface that can also be covered with fabric for a finished look.
