I owned IRS Gammas for several years. Arguably the best speakers I have owned. While the do not have the sensitivity of the K-horns, they will in fact play extremely loud. The servo controlled bass is the best I have ever had in my room. Reason for selling? Just like everyone else has mentioned...servicing. I had to re-cap the servo controller. Even after that, it still drifted in and out of calibration. I am knowledgeable to service and calibrate it myself, but still a PITA. The coating on the EMIM magnets was starting to peel. The L-EMIM is unobtainium (or really expensive if you can find one).
I have heard the K-horns on occasion. They sounded ok. I owned Klipsch Quartet for a year or so in my second system. I never really got into the Klipsch house sound and greatly preferred my vintage ADS L710 I have owned for 35 years or so. But if you are into horns, I think Klipsch are a very good choice. I think 17' is too far apart. You would probably be better served with Cornwalls or La Scallas.
Just my $0.02 coming from a die hard planar / dipole fan.
