Horn based loudspeakers why the controversy?

Kosst {I think their general behavior and theory is fundamentally flawed} in what ways are horns fundamentally flawed? you can think this all you want but its just a bias unless you have facts to support this bold claim. Kosst{ Logic suggests if I can't find them, nobody is trying to sell them because nobody wants to buy them} again non sequitur a logic failing  And this gem-Kosst{  And yeah, I'm absolutely biased against them }  Bias is prejudice in favor of or against one thing, person, or group compared with another, usually in a way considered to be unfair.  You invalidate your arguments with non sequitur and self admitted bias.

Kosst -Not one of my local dealers stock focal    Logic suggests if I can't find them, nobody is trying to sell them because nobody wants to buy them       No dealers selling tube gear in my area   Logic suggests if I can't find them, nobody is trying to sell them because nobody wants to buy them    never found a Ferrari at a dealer   Logic suggests if I can't find them, nobody is trying to sell them because nobody wants to buy them. Never found a bigfoot at my local audio dealer no mater how hard I looked  Logic suggests if I can't find them, nobody is trying to sell them because nobody wants to buy them.      Rise above Dunning Kruger.

Inventing your own definitions for words to make me say things I never said is pretty transparent and cheap. 
The basic concept of directional speakers is widely contested for a plethora of reasons. That's a very widely understood reality. The finest compliment that can be paid to a horn is that it doesn't sound like a horn. What exactly are we arguing about??? Are you that offended that what you call perfection sounds awful to somebody else? Is it impossible for you to imagine somebody liking something that's technically superior in many ways to what you like? 

What is a directional loudspeaker?

A conventional loudspeaker is designed to spread sound over a fairly wide area: it has a paper or plastic cone that moves back and forth, pumping sound in a wide arc in front of it. The more energy you feed into a speaker (in the form of electric current), the more energy it can pump out as sound, the further the sound waves can travel, and the louder they seem to be. Giant speakers used at rock festivals produce so much energy that they can be heard over a huge area, whether you want to hear them or not.

Most of the time this is exactly how we want speakers to behave, but there are times when it would be helpful if they could work more selectively. Suppose you're the captain of a giant, fast-moving warship and you see a tiny fishing boat moored just up ahead and locked firmly in your path. If it doesn't respond to radio contact, you have a problem. You could use a megaphone to try to call out, but that's just a basic loudspeaker, really, and the sound it makes will probably not reach far enough. Wouldn't it be neat if you could send out a very focused "shout," in a tight beam of sound, that would travel all the way to the fishing boat to catch its attention, even from a huge distance away? This is essentially what a directional loudspeaker does: it's a kind of "sound flashlight" that can "shine" sound energy into a precise spot, even from some distance away.
