Formedffusor ™ T
PRODUCT OVERVIEW 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. SIZING Standard Panels: • 23-3/4" W x 23-3/4" L x 4" D • Each panel weighs approx. 0.75 lbs/ft 2 FIRE RATING Class A (per ASTM E-84) FINISH The Formedffusor TM T Tile comes in a standard natural white finish and can either be painted on-site or factory color-matched to any paint color specification.
