Horn speakers are really bright?

I own Klipsch Lascalas II. They sound divine IN MY ROOM. WITH MY GEAR. I couldn't imagine them in the typical home with sheetrock, wood slab floors, glass windows everywhere. And then drive them with SS amps and I would want to sit on that pole someone suggested. They will painfully reveal room and gear mismatches. However, pristine tube power and an acoustically nearly dead room and pure magic. (I live in a yurt with a wall of books behind me in a half circle) The ceiling is fabric, as are the walls. I've put the 175 pound monsters up on isolation pads. The sub (SVS SB2000 Pro)  sits on a suspension rig to keep it isolated, Raven Blackhawk, Yamaha S2100 CD player in the rack also free suspended from all vibration. Ladies and Gentlemen, synergy is everything. Room, cabling, interconnects, fuses, tweeks all add up to happy days here in the sweet spot. Klipsch Lascalas are mellow fine companions for this old audiophile.  

I listened to both versions twice, but of course it's hard to tell on computer speakers, almost a joke. I did perceive a difference though. The original presented the vocal as slightly softer and more diffuse while the new driver seemed a bit more sharply focused. 

I'm curious as to why you chose that driver as I see that many that modify the Epics use an older Electro Voice compression driver. Had you considered that also?

@roxy54 

this new horn drivers don’t require any modifications 

Electro Voice compression need a lot of work to make it fit including bracing take all the woofers crossover and everything out little too much for me especially with two years old twins around me 95% of the time 😂😂😂

this B&C was recommended by a friend who try it and blow his mind 

the changes from original to B&C is bigger than any DAC , cables, PC and AMPS i have try with the exception of my Moon P8 Preamp 

With Moon P8 and W8 I hear zero  noise from tweeters with my ears touching it lol 

I have own  McIntosh C52  Michi P5 Parasound JC2 P6 Hint6 ROTEL RC1590 Classe CP800 SSP800 and more still P8 is my favorite Michi P5 ROTEL 1590 is worse Preamp ever owned 

I am going to have my Viking Acoustic Grande Voix Dual horn updated in a couple of weeks to include new drivers, Super tweeters, and caps.  I should do a before and after video,
