"Is it the Klipsch name that illicits this type of response (1) or is it Horn speakers in general? (2)"
[please excuse my bad English]
I am afraid it is the #1 answer.
But there is nothing wrong with your choice; after all, it has to suit you.
I heard the Klipsch Cornwall again recently at a show. I personally would not use them for my favorite classical music works (or any acoustic instruments recording), but with all other genres (especially rock & pop), I admit they can provide a lot of fun.
I usually hate horns. Nevertheless, I recently discovered some horn speakers that sing like divas (but are as pricey as a car).
Enjoy your music, whatever the speakers and others opinions.
