These were the last speaker that Paul Klipsch designed (with a smaller horn). The audio engineer( Roy) that worked with him heads the Pro division out of Hope Akansas. The new bean counters at Klipsch were going to scrape this speaker but Roy talked them into letting the Pro department have it. So it is sold mainly for commercial cinema use. These were custom made out of South African Mahogany for home. I still need to make some grills to cover the sides and have the horn painted in a high gloss automotive finish.
