Since its inception, 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 made the QRD^® a logical choice for almost any speech, critical listening or performance facility. The Formedffusor^TM T Tile brings this proven technology to a wider audience with its economical pricing, ease of installation, Class A fire rating, lightweight thermoformed material, durability and color options.

The Formedffusor^TM T Barrel is a high-impact, thermoformed unit in a basic shape. It is an economical solution in architectural acoustics used in band and choral rooms to blend the direct and reflected sound to increase intelligibility and enhance musical clarity and intimacy. Low-frequency absorption is also achieved. Units can be manufactured with internal stiffeners for increased rigidity and a liner for decreased bass absorption.

Pyramidal-shaped ceiling units redirect portions of the incident sound energy in different directions. While redirection is not true diffusion, the pyramidal shape offers a moderate amount of acoustic control, preventing excessive harshness and flutter and providing a more uniform sound distribution. Constructed of rigid, non-combustible glass fiber reinforced gypsum (GFRG), RPG's Golden Pyramid™ G Tile offers superior performance over other manufacturers' thinner, lightweight plastic models that can resonate and provide unwanted absorption.

The Golden Pyramid™ T22 is a high-impact, thermoformed unit in a basic shape. It is an economical solution in architectural acoustics used in band and choral rooms to blend the direct and reflected sound to increase intelligibility and enhance musical clarity and intimacy. Low-frequency absorption is also achieved. Units can be manufactured with internal stiffeners for increased rigidity and a liner for decreased bass absorption.
