Biffusor Overview The first general purpose variable diffsorbor. The Biffusor is reversable. One side is a QRD 734, the other is a combination product with absorbing material in the well base.  If this aesthetic is not pleasing, then another option is to have a QRD face and a standard absorbing face, similar to [...]

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 [...]

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 [...]

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 [...]

Diffractal Overview The Diffractal provides full spectrum sound diffusion in a single integrated diffuser. To achieve this, the self similarity property of fractals was combined with the uniform scattering property of a quadratic sound diffuser. This unique and patented design expands the bandwidth and offers the broadest spectrum of sound diffusion [...]

Waveform Spline The Waveform Spline -G represents the evolution in architectural acoustics toward quantifiable, organic shapes. The Waveform™ Spline-G is a single GRG unit, designed to blend the direct and reflected sound to increase intelligibility and/or enhance musical clarity and intimacy. One of the most powerful one dimensional sound diffusers available today, [...]

Waveform Monoradial Overview The Waveform Monoradial -G is a single GRG unit, a timeless shape in architectural acoustics used in auditoriums to blend the direct and reflected sound to increase intelligibility and/or enhance musical clarity and intimacy. When absorptive material is placed into the rear cavity of the assembled unit, significant reverberation [...]
