I have never had K-horns. Always been a big Klipsch fan though. I set up a home theater system with Cornwals as the front mains, Heresy for center, Forte's for the surrounds and some cheap plastic Klipsch for the rears. I used a Def Tech 15" powered sub and it was the best home theater system I have ever heard. Period.
Moved twice since then, all I have left are the 1989 vintage Forte's. Good luck, nothing does movies like super efficient horn loaded speakers.
