I am looking for information on the design of a Beveridge-type
"acoustical lens/waveguide" for electrostatic loudspeakers. It has
the property of taking a line source and bending it 180 degrees to
create a cylindrical wavefront. Of interest are dimensions of
waveguide, curves and/or plots for shaping the various channels to
bend the sound--and even the purchase of a "salvaged" or ruined lens
from an old B. speaker. Also, printed information and papers on this
item available in the public domain.
Has anyone applied this iventor's cylindrical wavefront concept to
other commercial electrostatic loudspeakers or has fabricated such a
"lens" for personal use?
All leads, ideas, suggestions and material greatly welcomed, with
my thanks:
