Formedffusor™

RPG Formedffusor™

Since it’s introduction in 1984, the number theoretic QRD® 734 Diffusor has proven to be a versatile general
purpose diffusor. It’s uniform scattering, wide bandwidth, and broad selection of finishes make it 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 color and texture options.

Problem

Furniture grade 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, plastic QRD®.

Solution

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

Features

• QRD® number theory sound diffusion 
• Lightweight thermoformed fabrication
• Low frequency diaphragmatic absorption
• Custom colors and textures
• Can be oriented to provide one or two dimensional diffusion in the far field - Panels nest into one another

Benefits

• Low frequency absorption can be used to control boominess in small rooms, while also providing uniform sound diffusion.
• Thermoformed panels are designed to nest for lower shipping costs
• Diffusors can be aligned linearly for diffusion in the direction perpendicular to the well direction or rotated 90° forming an alternating pattern to provide omnidirectional scattering
• 2' x 2' size offers more flexibility and higher diffusion performance than larger periodic
• 4' x 4' formats with a smaller repeat unit The Formedffusor™’s light weight makes handling and
