Welcome to ESS Laboratories
Proudly Made in the U.S.A.

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 licensed exclusively to ESS Laboratories 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 concentrate the sound unknown in conventional transducers. The sound signal moves five times faster than the air-motion of a conventional cone driver.


The sound is superior to any other sonic transducer currently available. With superb dynamic range producing the sharpest of images, and clarity and immediacy that replicate the breathless excitement of a live performance, it’s no wonder the ESS Heil Air Motion Transformers make such a lasting impression on all those hearing them.


While compact, the ESS Air Motion Transformer has the equivalent sound capacity of a conventional eight inch cone driver. The Air-Motion Transformer’s dispersal system provides a level of clarity unparalleled by conventional technology.


The Heil Air-Motion Transformer has set the industry standard, and continues to do so.   
ESS has made significant technological improvements. The system delivers “SOUND AS CLEAR AS LIGHT.”
