Horn based loudspeakers why the controversy?

I am enjoying a pair of Klipsch Lascala speakers, which are my 3rd pair. These have the " AL " crossovers, which I understand, were not designed by PWK, but by another engineer at Klipsch, designed to be a more " audiophile " crossover. I have dampened the horns, the drivers, the cabinets, and have dampened and isolated the crossovers. I have owned so much gear in my 50 years of this ( including many speaker types, and brands ), and, all I can say, I am extremely happy.  I do use subs for the lowest octave, and run the LS's full range. Thank you, MrD

Got to hear Klipsch  Heresy and Forte 3s today for first time.    Local dealer just started carrying these.   I was very pleasantly surprised by the Heresy 3.   I could live with those. 

Does the hearing ability of the individual make any difference in the opinion of horns?  It seems like they provide more directional energy  thus providing a better experience for those who have lost a little top end or detail in their hearing.  I have never owned horns, but the giant horns at audio shows always intrigue me and I would really like to hear them. 

I'm with mapman…I've mostly ignored Klipsch for decades, although in the 80s there was a KG4 or something that sounded pretty nice to me (I went with Boston A60IIs…I have a re-coned pair in my TV rig). I recently trekked over to a NH dealer to listen to a pair of Heresy IIIs and was also surprised with those things, although for many that's simply heresy. Might have to get a pair of those.
