Welcome To The ESS Labs Store!
ESS Laboratories has been an industry leader since the mid-1970s. The company has recently relocated its facilities in Southern California and is proud to announce the introduction of its enhanced ESS-Heil Air-Motion Transformer. The original air-motion transformer was created by the noted German physicist, Oskar Heil, and his patent was assigned to ESS for production in the United States.

The Heil Air-Motion transformer uses revolutionary, and unique, technology that remains unsurpassed and is state-of-the art. The key to the system is the design of its patented, double-sided diaphragm and its magnetic components that concentrates the sound unknown in conventional transducers. The sound signal moves five times faster than the air-motion of a conventional cone driver.
