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…

Representing RPG's continuing evolution in architectural acoustics toward expanding the palette of available surfaces and textures, this product is constructed of non-combustible glass fiber reinforced gypsum (GFRG) and molded from masonry…

A family of products developed using RPG's patented Shape Optimizer and Aperiodic Modulation Technology to create uniquely shaped organic and modern surfaces to diffuse and scatter sounds in rooms from small to large. Units can be…

Used in Auditoriums to blend the direct and reflected sounds to increase intelligibility, and enhance musical clarity and intimacy, these units are one of the most economical approaches to engineering performance spaces. Absorptive…

Pyramidal-shaped units, available in 2 sizes, that direct incident sound in different directions. The pyramidal shape, constructed of non-combustible glass fiber reinforced gypsum (GFRG), offers moderate acoustic control, preventing…
