 In 1979, John and Helen Meyer established Meyer Sound to produce reliable high-fidelity products for sound reinforcement professionals.Meyer Sound’s first product was the ACD/John Meyer studio monitor, based on a design Meyer developed while heading the acoustics laboratory at the Institute for Advanced Musical Studies in Switzerland.Prior to the founding of Meyer Sound, the Meyers started a relatively short-lived company named Glyph, which in part provided large speakers that were four to eight feet in diameter.
