2'x4' QRD Diffusers

About the 2'x4' QRD Diffusers

The ATS Acoustics 2'x4' QRD Diffusers utilize a 7-well quadratic residue diffuser (QRD) design that begins scattering sound at approximately 235-325 Hz and effectively diffuses sound up through 3 kHz. These diffusers help eliminate acoustical problems such as comb filtering and flutter echo, which can seriously affect sound clarity and detail in listening rooms, recording studios, and auditoriums. Unlike absorption panels that can deaden a room, these diffusers add spaciousness and retain the natural ambiance of the space. They are commonly installed on the rear wall behind the listening position or at first reflection points on walls or ceilings, with a recommended distance of at least 6 feet from the listener's ear to allow even diffusion. The diffusers are precision manufactured in the USA using computer-controlled equipment and come with a professional installation kit including aluminum clips, screws, and anchors for secure mounting on drywall, concrete, or wood walls. The 2'x4' size is ideal for stacking and fitting into small spaces, making them versatile for various acoustic treatment setups.
