Primitive Root Diffuser. Designed utilizing modulated prime root number theory, the math shows us that the reflected energies will be equal in all the diffraction directions, yielding an even sound redistribution pattern... Its special performance feature is that it virtually eliminates the specular component of the incident sound wave. This means that in terms of creating a sense of spaciousness, while supporting imaging, there is no equal. 1, record 3, English, - primitive%20root%20diffuser
