I am looking for information on the design of a Beveridge-type ”acoustical lens/waveguide” for electrostatic speakers. Of interest are dimensions of waveguide, curves and/or plots for the various channels--and even the purchase of a ”salvaged” or ruined lens from an old B. speaker. Has anyone applied this inventor\'s cylindrical wavefront concept to commercial electrostatics or has fabricated such a ”lens” for personal use?
