Page 144 is a full page ad for German Physiks loudspeakers. The ad copy includes, "The German Physiks omnidirectional driver is the only precision full range, point-source, bending wave omni driver in the world." The driver shown in the ad looks very much like a Walsh driver from the old Ohm A's and F's. The description of how the GP driver operates sounds very much like the Walsh driver. Can anyone explain to me the difference between the Walsh driver and the German Physiks driver that would make the GP version the only driver of its kind in the world?
