Horn speakers are really bright?

Here's what I've come to learn about Klipsches, DON'T PLAY LOUD ROCK MUSIC THROUGH THEM. That's where they get brashy, honky, and headachy.  Those horns are nice with certain genres at reasonable volumes, but crank them up with many types or rock/country and you're asking for an ear piercing. 

I was cranking the crap out of the Moana soundtrack (don't laugh take a listen) with the Klipschorns and Tektons next to each other and the Khorns made me want to wear earmuffs while the Tektons were smoother and more listenable at very high volumes and offered more chest pounding slam too.

So much depends on how loud you drive them.  Some people's "loud" is NOT loud to me. My loud is VERY loud and that's where the horns get shouty and ear piercing.  At the same volume, non-horn speakers like my Tektons are much more pleasant to rock to.  I've thrown many a party with the Cornwall and CF3... They certainly deliver but then you get to something like Celine Dions voice and you have to leave the room because it's very sharp.
