The DIAMOND� is a 3D-controlled dispersion multidirectional reflection panel with a depth factor that is logarithmically varied. It is, therefore, a three-dimension omnidirectional diffusion panel that controls primary reflections and fragments the energy in 64 vertices of incidence by using the theoretical numerical sequence ratio of the primitive root as a basis for calculation. It is built with ABS recyclable material, and its modular design makes it a particular and high-performance diffuser. The reflection angles were optimised according to mid-size room applications. The DIAMOND� is an acoustic diffusion element with a lozenge geometry. The front view refers to 64 interconnected polygons with four multiple sound diffusion angles, which determines a diamond shape. It was created in 16 singular modules that have a quadrangular base and different extrusion heights on each corner. The combination of those positions results in a geometrically scattering diffusion pattern with a very attractive shape. Thus, the DIAMOND� produces exceptional results of sound diffusion effect and provides spaces with considerable sound perception. Available in several colours.
