The Dimetric 550 is a bi directional quadratic diffuser. Designed specifically for ceiling mount it can also be used on walls. Phase differences created by the different but mathematically related well depths cause sound over a broad spectrum of frequencies to reflect off in varying directions. This effect adds a sense of spaciousness and a smooth sweet nature to the treated rooms acoustic signature.

Employing the correct amount of broad response diffusion to a listening environment avoids the ‘sucked out’, overly dry effect using too much narrow band absorption can create. Unfortunately almost all the so called ‘diffusers’ available on the market are just acoustic foam absorbers that may look vaguely like a real quadratic diffuser.

The Dimetric 550 is an affordable diffuser crafted from EPS for long life, light weight and sensible cost.
