Horn speakers are really bright?

I like the clarity , crisp and details of new horn driver’s better though original horn sounds natural both have the same smoothness 

Second version slightly better IMO.

which one 

first video with new horn drivers or second with original 

look  description on both  video by the way both Chromcast 

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?
