How much of High End Audio is Horn Speakers?

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 ;).

Got khorns in 1982. Upgraded to full volti audio in 2015. The improvement was astounding. Will have khorns until death do us part. These speakers could make a toaster sound good. Use tubes for amplification. Heaven on Earth. Have no apologies for Klipsch fans. Khorns now sound like a khorn should sound. IMHO

The advantage IMO of horn loaded speakers is their efficiency. The disadvantage is coloration, they usually have a characteristic horn sound, like its coming from a tube, which it is. 

 JBL have done a pretty good job of taming horn speakers, with wide waveguides and crossovers but at the expense of efficiency.
