Electrostatic Loudspeakers (ESL)

The traditional ESL in its basic form is not a new technology, and is regarded by audiophiles as an ideal technology for accurate sound reproduction compared with any other technology existing today.

Bell Telephone Laboratories made the decision in 1923 to develop a complete musical playback system consisting of an electronic phonograph and a loudspeaker to take advantage of the new recording medium. Bell Labs assigned the project to two young engineers, C.W. Rice and E.W. Kellogg.

 

 

 

 

 

 

 

 

 

 

 

 

 



After testing various audio reproduction devices, Rice and Kellogg had narrowed the field of competing technologies to the CCL and the ESL. Despite finding the ESL to be superior, the lack of available materials at the time made the CCL a more practical alternative. The evolution of the CCL progressed and it is now the dominant audio reproduction device used today worldwide. Since then, the ESL has developed into a premium product delivering a sound quality praised by most audiophiles..
