Golden Pyramid Overview The Golden Pyramid is a timeless shape in architectural acoustics, designed to redirect portions of the incident sound energy into different directions and so providing a more uniform sound field. In a drop ceiling application, the Golden Pyramid’s hard, GRG construction reduces the amount of sound energy removed by [...]

Skyline Overview Interfering reflections can be controlled by absorption or diffusion. In small rooms, it is often desirable to control interfering reflections and provide an ambient sound field using diffusion instead of absorption. When the room’s surfaces are relatively close to the listener, a very efficient diffusing surface is needed. To solve [...]

Skyline LP Overview The Skyline LP has been designed to offer efficient scattering in situations where available wall depth is limited.  In 100 mm maximum depth the Skyline LP scatters incident sound uniformly so that the acoustic glare in all directions is minimised.  No other diffuser on the market can claim equal performance [...]

Omniffusor Wood Overview The Omniffusor has become a classic shape in architectural acoustics, from its birth in 1990 it can be found in churches, schools, theatres and studios all over the world. The surface of the Omniffusor is designed to provide a more uniform sound field through mid and high frequency diffusion [...]

Diviewser Overview RPG Diviewser is the name for the 2 different types of transparent diffusors, the Omniffusor and the QRD. These units can be used in areas where vision is still required but acoustic control is necessary. The QRD® has become a classic shape in architectural acoustics, from its birth in 1987 [...]

Flutterfree Overview Flutterfree is an attractive, furniture grade acoustical wood plank designed for high frequency sound diffusion. Finish Flutterfree is available in hardwoods, softwoods and painted finishes. RPG offers factory color matching on both wood finishes and paint colors. See some of the options displayed under the Finishes tab below. Installation Flutterfree [...]

Planarform Overview The Planarform Reflector is used in auditoriums to blend the direct and reflected sound to increase intelligibility and/or enhance musical clarity and intimacy. The Planarform Reflector is a recycled, Class 0 fire rated, FSC certified, ULEF unit. When absorptive material is placed into the rear cavity of the assembled unit, [...]

Flutterfree T Overview Flutterfree T is an attractive, furniture grade acoustical wood plank designed for mid-high frequency sound diffusion. To achieve mid-band diffusion, RPG optimized an asymmetric well structure to reduce periodicity effects when installed properly. Finish Flutterfree T is available in hardwoods, softwoods and painted finishes. RPG offers factory color matching [...]

Modffusor Overview The Modffusor represents the evolution in architectural acoustics toward aperiodic sequencing of asymmetrical shapes . The Modffusor is a furniture grade, natural wood sound diffuser designed to provide a more uniform sound field through mid and high frequency sound diffusion while limiting the amount of sound absorption. Finish The Modffusor [...]

Modffractal Overview The Modffractal is part of the evolution in architectural acoustics toward aperiodic sequencing of asymmetrical shapes and provides full spectrum sound diffusion in a single integrated diffusor. To achieve this, the self similarity property of fractals was combined with the uniform scattering property of a phase optimised sound diffuser. This [...]
