Sound diffusers control standing waves that cause distinct echoes and reflections. Diffusers are used in conjunction with absorbers to eliminate standing waves in a sound space while providing a more realistic (live) sound environment. Our diffusion panels offer only one degree of flat surface facing the listener, increasing angular deflection because of there distinct shape. The slotted back of the panel allows the sound waves to pass through decreasing the amount of sound waves returning to the listening position and expanding the overall (sweet spot) of the listening area. The face of our product's unique round design allows coverage of a wider spectrum of frequency range.
