I take it instead of an acoustic lens � la Beveridge, the planar-magnetic driver itself is shaped as such?

Just a guess; the planar-magnetic membrane is shaped for wide dispersion (180 degrees maybe, horizontal and vertical?), inverted opposed triangles or such. Possibly something like the surface of an acoustic grating, something along the lines of an active RPG ;-)

The acoustic lens on the Beveridge was about 8" to 9" W and provided good directivity up to about 1500Hz. After that, beam city. I heard the 2SW about 20 years ago and liked it, but the store had them set up with the lenses facing the listener instead of each other.
There are no trianglar CD shapes in my patent.
