Designed using RPG's powerful shape optimization technology which optimizes sound diffusion while providing a given shape motif. The organic and modern contoured surface creates an asymmetric tile designed to provide a more uniform sound…

Part of the evolution in architectural acoustics toward aperiodic sequencing of asymmetrical shapes, these units provide full-spectrum sound diffusion in a single integrated diffuser by combining the self-similarity properties of fractals…

Combining the self-similarity property of fractals with the uniform scattering property of the number-theoretic reflection phase grating. Given the appropriate width and depth, it is possible to provide diffusion over any desired bandwidth…

Dado™ is a family of products incorporating a powerful union between architecture and acoustic performance. They can achieve a high NRC by utilizing ultra-fine 2, 3 & 4mm wide face grooves between non-perforated veneered/laminated strips…

Expo™ is the ultimate synergy between acoustical technology and architectural panel design. By using an optimal binary pattern of round and/or linear perforations, The Expo™ family of products achieves an excellent balance of sound…

A representative product of the evolution in modular sound diffusers toward asymmetric designs, making them compatible with the current research that establishes aperiodic/asymmetric sequencing as an approach toward significant performance…

A 1-dimensional stepped well sound diffuser with a unique design that does not rely on the traditional dividers between each stepped well and provides optimal diffusion bandwidth. Available in a high-recycled content, ULEF, Class A…

With its shallower 4-1/4" depth, RPG created this 2-dimensional sound diffuser to expand the product line anchored by the classic Omniffusor® (now Omniffusor® W84) – the first product of its kind offered to the market. It has been designed…

RPG created what has become a classic shape in architectural acoustics. The Omniffusor® (now Omniffusor® W84) is a 2-dimensional sound diffuser and, since its inception in 1990, can be found in churches, theaters and studios worldwide. The…

With its deeper 8" depth, RPG created this 2-dimensional sound diffuser to expand the product line anchored by the classic Omniffusor® (now Omniffusor® W84) – the first product of its kind offered to the market. It has been designed to…

A 1-dimensional sound diffuser that is the 1st of its kind on the market with a patented folded well design, this product extends the diffusion bandwidth into the lower mid-range frequencies in only 4-1/4" depth. The unit's natural wood…

Flat panels can be used in Auditoriums to blend the direct and reflected sounds to increase intelligibility and enhance musical clarity and intimacy and are one of the most economical approaches to engineering performance spaces…

Unperforated and non-acoustic, flat panels can be installed adjacent to other RPG products where acoustic panels are not required and can be used to fill out the space in a matching or contrasting veneer or color. Available in a…

Perfecto® is a family of products (micro, mini, standard options) that is a simple union between architecture and acoustic performance. Perforations can be from 0.4mm (micro) to 1.0mm (mini) to 12mm in diameter at 8, 16, or 32mm on center…

This diffuser has proven to be the most popular and versatile 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…
