Yes the Klipsch site gives you absolutely no help in terms of some pertinent specifications. I think they something to the effect that some or all of their speakers are 8 ohm compatible or some such nonsense. I pretty certain that the curve of most Klipsch speakers are not ideal for tubes but the high efficiency will cure some of the other ills.
I was fortunate enough to spend a few hours listening to Tri Mai's system a few weeks back. Tri is the owner of Tri-planar tonearms and I had one of his arms put on my Merrill-Williams table. Tri has a very impressive horn system that I think would make most horn enthusiasts drool. He uses modified Classic Audio speakers with Atma-sphere Novacrons (OTL) and a MP1 preamp. For what horn lovers like I havent heard many systems that deliver in these areas better than this system.
