Wide Range Electrostatic Loudspeakers

1. Principles of Design for Operation at Low as well as High Frequencies with Negligible Distortion

The article below was published in May 1955 in Wireless World magazine in the UK. Peter Walker, the author, was also the designer of Quad hifi electronics and electrostatic speaker right through the Quad 22 / II, Quad 33 / 303, and the ESL 57 and ESL 63 load speakers.

These articles cover much of the theory behind the design of practical electrostatic speaker.

A closer examination of underlying principles leads to the conclusion that the electrostatic loudspeaker may well supersede the moving coil for high-quality sound reproduction. Designs recently developed have proved to be capable of reproducing the full audio-frequency range, with harmonic distortions no higher than those of the associated amplifier.
