Schroeder Acoustic Diffuser "QRD 2D N7"
OverView
The QRD 2D N7 Schroeder Diffuser is a professional-grade acoustic panel based on the Quadratic Residue Diffuser (QRD) formula developed by physicist Manfred R. Schroeder. Designed with precision and made from high-quality sanded birch plywood, this diffuser enhances acoustics by scattering sound in a two-dimensional, spherical pattern.The design features 49 mathematically calculated well cells, providing effective diffusion across a wide range of frequencies from 500 Hz to 8000 Hz, especially targeting the midrange — the most perceptually sensitive area for the human ear.Thanks to its closed rear panel, deep 11 cm profile, and comb-joint frame, the panel ensures structural stability and acoustic efficiency.
