Professional QRD acoustic diffuser panels designed for superior sound diffusion in critical listening environments. These 600x600mm panels feature advanced quadratic residue design for optimal acoustic performance.

These QRD diffusers provide broadband diffusion across the 500Hz to 5000Hz frequency range, based on quadratic residue diffuser theory developed by German acoustician M.R. Schroeder. The 50mm thickness and precisely calculated well depths ensure optimal scattering of mid to high frequency sound.

• Broadband diffusion from 500Hz to 5000Hz
• Peak diffusion coefficient of 0.58 at 2500Hz
• Mathematically configured well depths for optimum diffusion
• Creates uniform sound distribution across listening spaces

• Recording studios and control rooms
• Home theaters and hi-fi listening rooms
• Concert auditoriums and music performance spaces
• Lecture halls and conference rooms
• Office spaces and meeting rooms
• Hotels and sports venues

Available in various hardwood types and custom paint finishes to match your design requirements. Matching trim pieces for top and bottom available as needed.
