Klipsch love them or hate them.

Horns provide a very forward, immediate sound, with lots of presence. Too much presence, having a severe "cupped-hands around a mouth"/"pinched nose" coloration that quickly becomes irksome. The worst speakers, by far, I've ever heard for vocals. The ones I've heard, anyway. But very dynamic, if that's your priority and you can live with the extreme level of coloration they possess. They do mimic the sound of the PA systems at rock concerts, which may be why rockers don't mind them. When I lived in my Band's house at the age of 21, our PA (Altec Voice Of The Theatre A-7's) did double duty as our stereo speakers.

Call them what you want most people when they listen to them have the WOW effect. They sound live. When you go to a real concert you don’t see a bunch of tiny speakers you see speakers with large drivers. If you want a live sound the Klipsch do much better than most.

Do you see people at a concerting saying "gee they sound different than my monitors at home" They don’t sound colored or harsh to me, but some peoples ears are more sensitive than others. There is not wrong or right to it but people saying things like colored and looking down on Klipsch because of this are not being realistic. And are over exaggerating things just a bit.

To me, all my monitor type speakers sound flat and one dimensional in comparison. Yes they might be more accurate on paper but they fail on the WOW department.

I am talking about the OLD Klipsch not the new stuff.

Bob, the thing is the sound heard at most concerts is coming from a PA system, which is what Klipsch speakers sound like. Live acoustic music does NOT sound like that. If a listeners reference is the sound of a PA system, Klipsch should be fine.

Horn speakers (or horn hybrids, as they mostly are) span many varieties, and I don't find above descriptions to be a common denominator on their better implementations. With my own horn speakers (based on the Belle Klipsch) as a point of reference: rather than sounding forward per se I agree they provide presence, immediacy and dynamics in spades (undeniable qualities, to me), but it's worth noticing how their sound morphs depending on the recording; some, if not most of the more modern rock/pop recordings can sound flat, uninvolving and compressed (which they are), but put on (particularly older) jazz titles and classical music and the soundscape suddenly blooms into a vivid, colorful and very dynamic presentation. I've never heard the likes of violin, cello, piano, clarinet, saxophone etc. sound that authentic, full of life and presence. Dynamics, both micro and macro, isn't just a priority here; it's an outright necessity if one is to emulate the imprinting of live instrumental sound, as is truth of tone, sheer air displacement area, ease and overall coherency. Perhaps much of the controversy of horn speakers resides in their unsuccessful pairings, be that both with the associated equipment as with the music (i.e.: their recordings). Add to that the inertia of what audiophiles are used to hearing from mostly (smaller) direct radiating speakers, and horn equivalents can be found to sound "wrong" simply by virtue of having a different, more direct presentation.

My first real speaker was an older pair of Cornwalls. THey were matched with 2A3 Wright Sound amps and a Philips SACD1000 that only worked for two years. I enjoyed them for what they were and being on a tight budget they were a value. 
Klipsch horns that I have heard over many years all sound good, not great and have issues. Slightly honky, harsh, bright with lacking soundstage are what I have heard typically.  I also know there are strong feelings both ways. Some in the hobby love to hate them and I don't think that is fair. A SET amp simple record player and Klipsch speakers can be had on a budget and be fun to listen to.
