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

I have found most Klipsch speakers lacking in very high frequency information. But I often find them fatiguing at upper midrange and lower high frequencies. A great deal has to do with pairing them with more forgiving (tube) equipment. I also object to the notion that horns are more sensitive to what they are fed than other speaker types. Granted higher efficiency can often highlight noise, but I think this is a different thing altogether. Best horns I have every heard were intoxicating in a few areas. I have only heard heavily modded Klipsch that sounded decent to me. Havent heard the new models however.
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.


I've long suggested this be a "sticky" here on Audiogon:

Sounds Like? An Audio Glossary | Stereophile.com

"bright, brilliant  The most often misused used terms in audio, these describe the degree to which reproduced sound has a hard, crisp edge to it. Brightness relates to energy content in the 4kHz-8kHz band. It is not related to output in the extreme-high-frequency range. All live sound has brightness; it is only a problem when it is excessive."
I’m consistently mystified by uploaded YouTube videos with the idea of judging system or music quality. 
However, I do like this discussion.
