The Optistep^TM G Panel 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 G Panel has been designed to offer optimal diffusion bandwidth. Constructed of heavy, non-combustible glass fiber reinforced gypsum (GFRG), RPG's Optistep^TM G Panel provides superior acoustic performance over similar lightweight gel-coated options by other manufacturers.

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.

Overture^® VR is an innovative new design in the field of diffusive surfaces for performing arts theaters. These units provide a mobile, collapsible diffusive surface that can be used to transform the sonic profile of a performance stage. Standing at 16’ in height in its performance position (shorter heights possible), each Overture^® VR unit is comprised of a rugged, powder coated steel frame upon which diffusive wood panels are mounted. The panels are removable and interchangeable to achieve diffusion along either the horizontal or vertical plane, or to substitute a different diffusive RPG panel to suit the acoustical needs of a particular application.
