Horn speakers are really bright?


So I’m trying to understand why so many people think klipsch or horn speakers are bright 

I have two  set up garage and living room both with horn speakers EPIC CF4 garage and and KLF 30 mahogany living room  

I have recorded this songs with my iPhone  listen to them and feel free to tell me what you don’t like about them
 by the way I don’t have any room treatment

Having owned Khorns and LaScalas for many moons, they were far from being bright. I did own a pair of Hersey II's I found to be bright in 2 channel, but then used them as rears in a Klipsch 5.1 system I had 20 years ago. If they were bright the Velodyne FSR18 I used definitely fixed that issue. 
in homes i've heard mellow klipsch speakers and harsh klipsch speakers, sometimes among the same model. i've heard sharp khorns and mellow khorns, i can only conclude it was the room and/or electronics that did them in. in the showroom, the tower klipsch speakers invariably sounded "hot" and "upper-midrangey" compared to the speakers next to them. 
I have listened to Klipsch speakers since 1975, I have found everyone painfully bright.
Not quite (technically) horns, but the waveguides on my JBL 4349's are delightful.  I can listen for hours with no fatigue and they fill my room very well.  Took a bit to get the right amp and preamp match though.
