PYRAMID DIFF– USERS – Interactive Series

The Lamvin Inc. Interactive Series includes Diffusers and Absorbers. This series of products is the ultimate combination of sound reflection and absorption. Diffusers feature a convex or pyramid shape with reflective surfaces to diffuse sound within a zone. Absorbers are designed to adjust the sound level of a room. Absorbers and diffusers are interchangeable.

Diffusers are ideal for venues such as theaters and auditoriums, which demand exquisite sound quality and enhanced acoustical performance. Barrel and pyramid diffusers disperse and blend sounds within a room, greatly reducing sound waves and echoes.  The pyramid shape uniquely radiates sound from its surface, providing a balanced distribution of reflective sound for a broad range of frequencies.
