Vicoustic VICU04281 Multifuser Wood 64 MKII Acoustic Panel (Natural Wood)Made from solid wood, the natural wood 4 piece Vicoustic Multifuser Wood 64 MKII Acoustic Panel is perfect for use in venues such as concert halls, hi fi rooms, and recording studios, where effective diffusion is often required, without too much absorption occurring at the same time. With its striking angled surface, the two dimensional diffuser is based on a QRD sequence combined with changing reflection techniques (a result of the angled surface).
