Primacoustic Razorblade Quadratic Residue Diffuser - Black - 24" x 48" x 8" Trumpet Mouthpieces explosive response is fast andThe Razorblade is a high performance quadratic residue diffuser (QRD*) based on a primitive root sequence that employs a grated array of 17 precisely calculated wells to break up and scatter acoustic energy to create a diffuse sound field. Originally developed by Schroeder, QRDs have long been considered to be one of the most effective forms of diffusion. A series of wells are mathematically arranged in such a fashion that sound waves entering the
