How much of High End Audio is Horn Speakers?

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.

"Is it the Klipsch name that illicits this type of response (1) or is it Horn speakers in general? (2)"

[please excuse my bad English]

I am afraid it is the #1 answer.

But there is nothing wrong with your choice; after all, it has to suit you.

I heard the Klipsch Cornwall again recently at a show. I personally would not use them for my favorite classical music works (or any acoustic instruments recording), but with all other genres (especially rock & pop), I admit they can provide a lot of fun.

I usually hate horns. Nevertheless, I recently discovered some horn speakers that sing like divas (but are as pricey as a car).

Enjoy your music, whatever the speakers and others opinions.

Have had Rectilinear, Visonik, ADS, Maggies, Thiels, Acoustat, M&K, Salk (still have these), and probably a few others I've forgotten, and have no complaints on running Forte IV's in my main (of 3) system.
