Horn based loudspeakers why the controversy?

Having heard the newer Klipsch offerings, I’m going to go out on a limb and say horns need no longer be so controversial. Affordable good sounding ones are out there. Like anything else some will like them and some will not. Their clear advantage is the extra efficiency which may well matter quite a bit for many. No harder to drive than most others at a minimum as well it seems. Probably much easier to drive properly than most.

Regarding horn use and abuse, I use a pair of Mackie 10" 2 way P.A. passive (passive aggressive) speakers (with a beefy Mackie sub since they’re good to maybe 60hz) daily for my mindless but important electric guitar noodling in my mindless noodling studio setup. Note that the these little gems are the original version that cost around 300 bucks a pair new and seem to be made from some sort of plastic cement (heavier than the latest "neo" magnet woofer version which I imagine also sound real good). Interestingly, if you put recorded music through these (as opposed to my noodling tracks) it sounds sort of great. Heresy again. Plus, I’m not sure I spelled "noodling" correctly but it looks right.

kosst reads about how things sound not listens. And adds so much unsupported BS like this gem [ Horns have problems that aren't cheap to fix] no list of problems no hands on experience with said problems. I say kosst why even comment on horns when your experience levels zero and your bias towards what you own is 100%? And why do you think a corner is a bad place in a room to house a speaker designed for it and about a meter or more out is somehow more room friendly? And since you have no hands on why should I value your other bold proclamation of no klipsch being high end. Come out from under the bridge. 

Kosst I’m referring mainly to the heritage line.  Have not heard the others enough to judge meaningfully.
