QRD® 734 has proven to be the most popular and versatile diffusor in the RPG product line. Its wide bandwidth, low cost and a broad selection of finishes make it a logical choice for music education facilities, recording studios, worship spaces, auditoriums, theaters and performing arts facilities. This 1-dimensional diffusor is a modular, computer-designed phase grating that produces a directional hemidisc polar response that can be oriented in any direction. The surface of the QRD® 734 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.
