QRD 734
QRD 734 is a 1D quadratic residue diffuser, first introduced in 1987. This classic diffuser was designed to provide a more uniform sound field at mid and high frequencies while limiting the amount of sound energy removed by absorption. The QRD 734 comes in a wide variety of finishes, including wood veneers, laminates, melamine coatings, and painted surfaces. Wooden cleats are provided for easy mounting direct to walls and ceilings, or it can be laid into a T-bar grid.
Diviewsor is the same QRD 734 design but fabricated in acrylic, which may be clear, frosted, or have varying levels of opacity.
