Project Description

The QRD has become a classic shape in architectural acoustics, from its birth in 1987 it can now be found in churches, schools, theatres and studios all over the world. The Formedffusor is a moulded unit based on the QRD and designed to lay into a standard 400 mm T-Bar ceiling grid. The surface of the Formedffusor is designed to provide a more uniform sound field through mid and high frequency diffusion while the thin wall construction adds some low frequency absorption via membrane resonance at the face.

Since its introduction in 1984, the number theoretic QRD 734 Diffusor has proven to be a versatile general purpose diffusor. The uniform scattering, wide bandwidth, and broad selection of finishes make the QRD a logical choice for almost any speech, critical listening, or performance facility. The Formedffusor brings this proven technology to a wider audience because of its low price, ease of installation, Class A fire rating, light weight, impact resistance, and colour and texture options.

Wooden QRD diffusors may be too heavy for some ceiling applications or too expensive for large scale coverage. There is a need for a lightweight, Class A, cost effective, molded plastic QRD.

To address this problem, RPG developed a lightweight, thermoformed panel made of Class A Kydex. The diffusor has a graceful curved inner and outer radii for an attractive appearance. Kydex is stiff and impact resistant, allowing the Formedffusor to be use in almost any wall or ceiling configuration.

The Formedffusor is readily available in a standard white and grey finishes. Custom colour units are available or standard units can be colour matched to any paint colour specification.
