Overview Hemiffusor is the first two-dimensional QRD - ideal for Home Theatres and Project Studios. Conventional acoustic treatments have relied on absorption for reflection control. Unfortunately, this can "deaden" the room and result in making it unsuitable for speech and music. Diffusive ceilings are one of the most effective ways to [...]

Skyline Overview Interfering reflections can be controlled by absorption or diffusion. In small rooms, it is often desirable to control interfering reflections and provide an ambient sound field using diffusion instead of absorption. When the room’s surfaces are relatively close to the listener, a very efficient diffusing surface is needed. To solve this [...]
