Horn based loudspeakers why the controversy?

@johnk
You’re presumptions about my experience with horns is as wrong as you claim my opinions are. Klipsch horns in particular were the definition of honky horns for a long time on account of their big, very resonant horns. I get the impression from the glowing adoration of horns by some here that their significant shortcomings are being ignored. Just like any transformer, they color sound. Like any transformer, the degree and quality of that coloration is a product of the design and materials used. And just like any transformer, better ones are more expensive by virtue. Horns are NOT just better regardless of how they’re made.
The Palladium series did look like fine products, but they apparently didn’t compete with conventional speakers well.
As for the required corner placement, who exactly has two ideally located corners from their listening position? You basically need an ideally proportioned room to be sure the speaker placement is the best. That strikes me as a significant design failing.

I just want to be clear that I'm not saying the modern Heritage line is a bunch of junk. Like the Porsche 911, they've taken a design with significant faults and refined it into something quite respectable. 

"The Palladium series did look like fine products, but they apparently didn’t compete with conventional speakers well."

They did not compete well mainly because of price points.  At $20,000 msrp for the P-39Fs, these were a huge step up for Klipsch that many "loyal" Klipsch fans just could/would not swallow that pill.  At that price Klipsch would be rubbing shoulders with some heavy hitters and they had not "proven" they belonged in that elite group.  Many non Klipsch folks were just not willing to give them a chance, and I get that.

At some of the current used prices out in used speaker land, these Palladiums are becoming a powerhouse performance bargain.

I'll bet half their problem is their website. Go there and try to find a dealer stocking a pair of Heresy. In my area I get every ABC Warehouse, Best Buy, and a few electronics shops I've never heard of. You can be sure Best Buy and ABC Warehouse aren't stocking heritage gear and their website makes no distinction. I wouldn't know where to hear a good pair of Klipsch without calling shops for 15 minutes. That's a problem.

I can speak for myself in that such is certainly not the case. Horns can sound as good or as bad as anything else.
