Omniffusor ® W84
PRODUCT OVERVIEW Omniffusor ® W84 has become a classic shape in architectural acoustics. It is a 2-dimensional sound diffuser and, since its inception in 1990, can be found in churches, schools, theaters and studios worldwide. The surface of the Omniffusor ® W84 is designed to provide a more uniform sound field through mid and high-frequency diffusion. In contrast, the natural wood construction of the unit, available in a high recycled content, ULEF, Class A fire-rated and FSC MDF core, limits the amount of sound energy removed by absorption. SIZING • Standard Unit 23-5/8" L x 23-5/8" W x 4" D • Each panel weighs approx. 3.75 lbs/ft 2 CORE FIRE RATING Class A (per ASTM E-84) FINISH Omniffusor ® W84 is available in natural and engineered wood veneers and laminates with clear lacquer or factory color-matching of wood finishes and paint colors.

INSTALLATION Omniffusor ® W84 is designed to be surface-mounted to a wall or ceiling with factory-integrated blocking or dropped into a standard 15/16" HD T-grid supplied by others. These panels can also be installed adjacent to Omniffusor ® W58, W76 and W113 units for comprehensive broadband diffusion performance.
