Designed and manufactured by Stereotech, in Brisbane, Australia.
The Metric 550 is an accurately designed quadratic residue diffuser. This a diffuser design that genuinely diffuses sound waves that collide with it. 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 creates. Unfortunately almost all the so called ‘diffusers’ available on the market are just foam absorbers that may look vaguely like a real quadratic diffuser. The exceptions to this are quality products such as the Primacoustics ‘Razerblade’ or Artnovian’s “Lugano”. The former offering somewhat broader range performance than our ‘Metric 550’ due to it’s extra depth (nearly 100mm deeper) but at a considerable price and convenience premium. The latter offering similar performance to the Stereotech product but at a price and availability premium.
The Metric 550 quadratic diffuser by Stereotech Australia offers perhaps the most affordable serious diffusion acoustic treatment available today. Made in Brisbane Australia in the Stereotech factory from Australian sourced materials. Available in a variety of colours either ex stock or with a minimum of delay. Custom painting to suit your project is available at a small premium on orders of 12 or more pieces.
