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, lightweight and sensible cost. It is manufactured in our Murarrie factory in Brisbane, Australia.
