Installation
Diffusers are most commonly used on the rear wall behind the listening position, but they can also be used at first reflection points on the walls or ceiling. We recommend the diffusers are at least 6 ft away from the listener’s ear to allow space for the even diffusion to take place.

Our professional installation kit is included at no extra charge. Includes aluminum clips, screws, and anchors for neat and secure installation on drywall, concrete, or wood walls.
