The Auralis QRD Sound Diffuser is engineered to control echoes and enrich the character of sound within a space by scattering audio energy across multiple directions rather than reflecting it uniformly. Using a carefully calculated quadratic residue sequence design, this diffuser reduces harsh reflections, eliminates acoustic focusing, and spreads sound evenly to create a more natural, spacious listening environment — ideal for studios, theatres, performance venues, and high-end residential rooms seeking refined acoustic control without deadening the space.






Guided by world-class acoustic expertise and architectural sensitivity, we shape silence as an experience where performance, design, and spatial wellbeing exist in harmony.
