Beveridge Audio

Beveridge Audio, LLC, was formed to preserve and extend the audio design work of Harold Beveridge. Specifically, the company is engaged in the repair and manufacture of full-height, full-width, full-range, cylindrical wavefront electrostatic loudspeakers.

At this point, the company is able to:

  • repair transducers (both circuit-board and epoxy-style) made by "Harold Beveridge, Inc." and "Cal Audio, Inc."

  • create new epoxy-style transducers, with greatly increased accuracy and consistency

  • design and fabricate new acoustic lenses, using computer-based mathematical modeling techniques

The company is currently working on a production exercise, building five pairs of "Model 2" replicas. These systems will be available for sale soon; please contact the company if you are interested in reserving one.
