Optistep ™ W
PRODUCT OVERVIEW Optistep TM W is a 1-dimensional sound diffuser developed to expand the product line anchored by the classic QRD ® 734 - the first product of its kind offered on the market. With its unique design which does not rely on the traditional dividers between each well, the Optistep TM W has been designed to provide optimal diffusion bandwidth. At the same time, 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 Units: 16" W x 23-5/8" or 47-1/4" L x 8" D (Custom panel lengths up to 8' are available) • Each panels weigh approx. 6.00 lbs/ft 2
CORE FIRE RATING Class A (per ASTM E-84) FINISH
Blue = Diffusion Coefficient Green = Scattering Coefficient Red = Absorption Coefficient
