Horn based loudspeakers why the controversy?

 Everybody has horror stories about hearing horn's. I remember the first time I went to addition a pair of model nineteens. The owner had them hooked up to a solid-state Mac and proceeded to turn them up so they were playing at about 120 DB steady. He looked at me with a big smile  and said see how clear they are? He didn't even have them set up properly, had  them facing one another across the room. I couldn't get out of there fast enough. Thankfully down the line I had some reasonable experiences  and grew to appreciate horns greatly. 

 Regarding Altec A7's I had a pair for a while and after quite a few mods they can sound quite good.  

Well, being an owner of new Klipsch Forte III's, I thought I'd chime in. Had Magnepan .7's for awhile and really liked them. In my listening area I knew I was only getting about 75% of what they could deliver because of space considerations. Took the plunge on the Forte's (my 3rd pair of Klipsch over the years). I can say I am very pleased and frankly, pleasantly surprised. They are the most refined yet dynamic sounding Klipsch I have owned. They aren't for everyone but with my taste in music being primarily electric blues and classic rock (Yes spinning now) they fit the bill. One man's trash, another's treasure. Using a Rogue Sphinx with upgraded tubes with splendid results...

How exactly do you figure inefficient speakers can't be dynamic as all hell given robust power? That math doesn't work. Sure, many inefficient speakers are limp on account of torpid power, but there's nothing inherent preventing them from being dynamic. You accuse me of relaying outdated or inaccurate information, but what you're saying hasn't been true since the power wars of the 70's. 
No offense, but you and johnk seem to believe audio hit it's zenith in 1935 or there about and everything since has just been regression. No matter what anybody seeks, you two prescribe massive horn loaded solutions and low power tubes. Prescribe for me the fully horn loaded full range speaker that will fit within 2 or 3 square feet and is suitable for listening at 10 to 12 feet using modest solid state power that costs less that $5000. I think those are very common demands of a great many people here. You guys can't even bring yourselves to admit those speakers don't exist, much less appreciate that's not a practical solution for many. At least HR admitted the 936's came surprisingly close to the dynamics of the Uno Nano's so I know I'm not listening to a couple of compressed piles of junk. You and johnk and a few others talk like there's some vast chasm of difference and that no shortcoming of horns compares to the failings of dynamic drivers. It's frustrating to those who don't agree. And you guys just don't take no for an answer. 

The real irony to me is that the same people who vehemently argue for the dynamics of horns are the same who think vinyl is king. You don't get more dynamically compressed than vinyl. Why the big concern about your speakers dynamics when your source can't utilize the capability?

My first my first encounter with horns were Klipsch La Scalas driven by early transistor amplifiers. Not pleasant—but great party speakers. Ditto classic Klipschorns. Never heard these with any kind of tube amp, let alone an SET. Fast forward 30 some years and I heard a pair of Avant-garde Duos driven by an all-BAT tube system. Astounding! The bass (which is delivered by a conventional powered woofer), was not dialed in at all, but that was not the speaker’s fault. Victor Khomenko, BAT’s designer just hadn’t gotten around to that. He was running a prototype of a new phonostage and he wasn’t listening for the bass. Victor is big on what he calls “dynamic tracking” and horns do that very well. At very low levels, many speakers just don’t respond at all. They operate like a noise gate in a recording studio; everything below a certain threshold is just swallowed up, rather than being reproduced. Horns avoid that problem, although they have others including, sometimes, significant coloration and a lack of low bass (unless they are really large, like a K-Horn).

Kosst- Altec -a7 a5, Klipsch- Lascala Belle Khorn all run well off class A SS all are under 5k pair- fully horn loaded systems get large and thus costly. Also since you only know me from a few posts in this forum you are not aware that I design loudspeakers and many that I have sold are non horn loaded designs. You also seem to form wrong conclusions based on having limited experience with horn based loudspeaker systems so I can understand why you find loudspeaker discussions complicated and frustrating. And I do feel I have the right to suggest horn loaded options in any forum at anytime I dont see why that is such a issue for you?  And why do you insist others agree with you?  Sorry but I haven't read much of what you post and what I have I haven't seen anything to agree with.
