Horn based loudspeakers why the controversy?

Are we now establishing here that speakers that exhibit confined directionality and stunted bandwidth are undesirable for high fidelity? If not, I'm confused by this. There's no shortage of speakers or designers bending over backwards with shapes and materials to reduce or minimize the directionality of their designs in the interest of smooth tonal accuracy. Focused directionally is widely considered a bad thing for hifi. I don't understand why somebody would want that in their living room. 

 Your confusing directional loudspeakers with horn designs and they are not the same thus why you are confused a directional loudspeaker is kind of "sound flashlight" that can "shine" sound energy into a precise spot, even from some distance away great for a LRAD blasting a pulsing irritating tone at pirates it is not a loudspeaker for home audio use so yes no one would want a LRAD or directional loudspeaker for home use. The issue here is you do not comprehend the basics of how loudspeakers function or any definition or classifications of different design you lump all as one without realizing loudspeakers exist for other uses besides audio reproduction.  Do not expect anymore reply's.

Again, you're trying to make me say things I never said and I'm getting tired of your flagrant intellectual dishonesty. You say I don't understand how these things work. Have you never looked at the dispersion plot of a horn speaker? They're basically worthless 15 degrees off axis up and down the spectrum. Are you going to tell me that's NOT directional??? That's almost as bad as big planars and nobody considers that a strength of planars. 
You question why horns are so controversial. It's no mystery to me why you don't see it. You embrace the failings of horns as virtues. I'm not attacking you for that. We all make our compromises to get what we want. That's fine with me. 

I’m not sure if my recently acquired Klipsch Heresy III speakers have a dispersion plot published anywhere (they likely do), but whatever sort of phase plugs they’re using in the horns works very well at dispersing frequencies hither and yon…especially yon. I have decades of experience using horn loaded PA stuff (actually am mixing a jazz show tomorrow…you’re all invited!) although the Heresys are my only recent horny (horn-ish?) home audio items (not counting my old A7s), and if anybody is interested, look up the dispersion plots for Mackie or other modern horns and you can see they often are very dispersy. I can only assume Kosst is part of a plot directly dispersing anti dispersion misdirection.
