Greetings folks. I have long been a fan of folded corner horn ( Hartsfield, Klipschorn ) designs. Tooling around the Internet, I found information on the Electro-voice Patrician IV. It is described as a Klipschorn scaled up 16-2/3%. Anyone have any thoughts on using an 18" 2245H in one of these designs? I have the components to build a 4345, but a scaled up Klipschorn might be worth the effort. Any thoughts? I am just waiting on acquiring a router big enough to handle a Freud lock-miter router bit. Thanks, Stevedel.
