Pyramidal Sound Diffusers


Pyramidal diffusers quickly and easily eliminate floor to ceiling standing waves.  They reduce flutter echo while maintaining a warm room sound. Molded in a one-piece pyramid shape, their offset apex provides four different angles of reflection.

The internal cavity of the Pyramidal Diffuser can be lined with a 1˝” thick layer of glass fiber batting to increase absorption and prevent resonance.
