The 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 device reflect back into the room at different times, thus shifting their relative phase. This produces both spatial dispersion (left and right) and temporal dispersion (time shift) which effectively eliminates flutter echoes, breaks up strong first order reflections, and reduces standing waves without overly deadening the space.
