The EQ Acoustics QR Diffuser is an innovative acoustic panel that combines variable diffusion with absorption. It disperses (high frequencies), controls early reflections, and eliminates unwanted acoustic phenomena such as flutter echo and standing waves. The QR Diffuser can be installed on walls or ceilings and is suitable for any space, such as music halls, recording studios, etc. As a result, it achieves effective and uniform diffusion of early reflections and contributes to achieving diffuse sound in the space.
