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 [...]

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 [...]

BAD Arc Overview The BAD Arc is an advancement on the traditional, flat BAD Panel, a synergy of advanced acoustical technology and simplicity of design for when performance is paramount. Using an optimal binary pattern of perforations through a Class A fire rated, curved rigid template, the BAD Arc achieves an excellent [...]

Broadsorber Overview The Broadsorbor Panel consists of a multi-density, high performance acoustical core with hardened square or shaped edges and wrapped in an acoustical fabric. The Broadsorbor Panel offers the broadest and most consistent absorption coefficient available with little deviation in the performance bandwidth between 100Hz and 4000Hz, yielding a balanced NRC [...]

DiffusorBlox Slot Overview DiffusorBlox Slot simultaneously offers a distinctive appearance, broadband sound absorption (NRC 90), extended low frequency absorption, sound isolation, and sound diffusive reflection control (when painted). This acoustical concrete masonry unit offers unprecedented economy by making it possible to incorporate complete acoustical performance into the structural walls of music, speech, [...]

Absorber Baffle Overview Sound can either be absorbed, reflected or diffused. In many rooms, flat reflective surfaces can cause interfering reflections and excessive reverberation, which corrupts music quality, speech clarity and general hearing comfort. One approach to controlling these reflections and excess reverberation time is to use absorptive panels. RPG have developed [...]

Abffusor Overview The Abffusor is the industry’s first absorption phase grating. It is an extension of RPG’s research on the reflection phase grating which provides sound diffusion from a series of divided reflective wells of equal width and different depths. The depths of both the reflective wells of the RPG and the absorptive wells of the Abffusor are [...]

Absorber Cubes Overview The fabric wrapped, fibreglass acoustical panel is the work horse of the industry, providing the most economical solution for general reflection and reverberation control to provide functionality for a wide variety of applications. The Absorber Panel is a 96kg/m³ ft rigid fibreglass board with hardened, square or shaped edges. Select [...]
