How much of High End Audio is Horn Speakers?

Well, if you never heard such a setup, you cannot comment based on experience.  As I write this I am sitting 8 ft from a horn setup in a most sized room.  I have heard few systems I like more than what I have (those too were horn systems), and I’ve heard quite a number of single driver full-range systems and multi-way systems with full-range drivers.  I might be persuaded to trade in my horn system for a two-way system utilizing a Jensen M10 fieldcoil full-range driver and a Western Electric 597 fieldcoil tweeter, but then again, maybe not.  At a much lower price point, I could live with a single-driver Charney Audio speaker (with the AER driver).  In other words, there is more than one approach to design that sounds good and there is no need to insist there is only one way, much less one particular set of components, that sounds good.

Small room filled with stuff, typical Japanese audiophiler, Horns are 1/2 of one of 2 maybe 3 rooms. I've seen a few that way. BIG Tannoys in custom hand made hardwood cabinets.. I love it.. Makes sense to me.. I really like Imperials. too.

I wish I had a 20 acre speaker Museum. Makes even MORE good sense come to think of it.. :-) Second as a solar farm. Man oh man!! :-)

single-driver

Note most big high end horn SYSTEMS have more than a single driver.

This dual thingy worked out really **splendid* to use a old english slang. In spite of the Society of FR Entheusiasts who all voted to give me the boot out of THEIR Club over at DIY, I broke THEIR rules ,,dual FR are not allowed + cabinets MUST be built by EXACT specs , tests, graphs, comp program models, Dindt learn a d**n thing over there. Just a bunch of babble. I can’t live with a single FR, not enough zing factor. My 2nd tweeter arrives tomorrow. Horns might make a deeper sound, larger than life soundstage, but these duo’s are working out OK. Worlds only FR Duo’s. haha

Friends don't let friends listen to self-important snarky posts.

So...I've dabbled on and off with Klipsch too after having polar opposite speakers in my system. I run a Pass 250.8 amp, Pass XP10 Pre, PS Audio DS Jr DAC and have a REL s5/SHO sub, with a JL audio F113 v2 on the way. I have a dedicated 13x22 listening room that's acoustically pretty tight. 

I've had Focal 1038 BE, Focal Sopra 2, B&W 805 D3, Harbeth 30.2, Harbeth HL5 Super Plus and several others. Of all of these the Focal 1038 and Harbeth HL5 stood out as most musical. Last year I tried a pair of Klipsch Heresy 3 for a few months - they did a lot right but had a mid bass hump and some "honkiness" in the mid on some music. Being on the floor also lowered the height of their sound staging. A few months ago I bought a pair of Klipsch Cornwall 4 after reading great reviews and hearing from a friend of mine how much he loved his. They turned out to be really good, musical and great with both low level and "crank it up" levels. I listen to jazz, funk, soul, acoustic, etc. They speakers are pretty big- and I put them on 6" amp stands, with minimal EQ in Roon to lower some bass around 80-125 hz, they sound really good- huge soundstage, no honkiness  and integrating my sub was easy too. I think they deserve more respect than they get but who knows, we're all opinionated about our gear. They do have a problem with fitting into a typical room's decor due to their size however. But, that's what second and third systems are for ;).
