Bluetone QRD 2D is a classic two-dimensional QRD diffuser that provides high quality acoustic diffusion from about 700 Hz to 2.5 kHz. The design is based on the quadratic residue sequence for the prime number 11. It is a 2D hemi-disc diffuser, meaning it disperses reflections by spreading sound energy in the horizontal and vertical plane. This panel allows for a reasonably controlled acoustic quality, by fragmenting the reflected energy, without the absorption factor being too high.
Bluetone QRD 2D Diffuser provides excellent sound diffusion in mid and mid-high frequency range and additional scattering below and above the diffusion range. It can help you to achieve a more spacious feel in your room. 2D diffusion is often used on the front wall between speakers, and on the rear wall to improve listening transparency without absorbing back wall reflections.
