Description
Quadratic diffusers have long been a classic shape in architectural acoustics. JOCAVI revisited the oldest acoustic diffuser design, starting from the same quadratic-residue calculations and adding an energy-flow calculation that improves scattering.
NEO 3Q has a three-grade pattern that distributes energy homogeneously across its effective range. Its phase-grating surface gives a more uniform diffusion of reflections, mostly in the mid and high frequencies, which helps against flutter echoes, early reflections and comb filtering where more absorption is not advisable.
Made of HIPS with a composite filling of recycled materials, which gives it mass, durability and impact resistance.
