THE LEGENDARY KLIPSCHORN® - A fully horn-loaded loudspeaker of superior design and exquisite craftsmanship by Jim Hunter and Matt Sommers

Chapter 16 | EXPANSION AND INFRINGEMENT

Now patent protected, PWK leveraged his products’ performance and popularity to create new revenue streams for his company. The first legitimate Klipschorn licensee was England’s Vitavox, who marketed their own version. As early as 1950 Radio Shack was also licensed for a less expensive model. Dominion of Canada was licensed, as was Electro-Voice, with models such as the Aristocrat, the Patrician, and the Georgian.

However, there were companies who tried to profit from Klipsch-protected designs without an agreement to do so. PWK eventually filed patent infringement proceedings against Brociner – along with Jensen, Speaker Lab, Permoflux, Angle Genesee, High Fidelity House, and Terminal Radio Corporation – for producing unlicensed knock offs of the Klipschorn under different names.
