Diffuser that diffuses in two planes


Conventional acoustic treatment has mainly focused on absorption for reflection control. Diffusion is another way to control reflections which preserves a more natural ambiance. The RPG Omniffusor diffuses and scatters the sound into many directions. Often used in ceilings but can be wall-mounted as well.


The RPG Omniffusor is a 2D QRD diffuser that scatters the sound uniformly into a hemisphere. In other words, both horizontally and vertically. It can be mounted both in ceiling and on walls. The product has low degree of absorption, and can also be offered with built in light aperture (named RPG Liteffusor).

Omniffusor comes in two versions:
– FRG Omniffusor is made out of gypsum, is class 0 fire rated and 100% recyclable.
– Omniffusor is constructed from MDF and can both be painted or have a veneer surface.
