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.  

Crazy as it was, my first serious upgrade was to buy a pair of new Klipsch Lascalas II. Immediately they were hooked up to an inferior system. Cambridge receiver, cheap CD player, stock cabling. As the last few years have passed I've replaced each link with an upgrade I could afford. The Klipsch's revealed clearly each change and revealed the capabilities of those horns. Also they painfully told me there was more to change. Many times I thought the particular issue was the speakers themselves only to find out later the real issue was poor interconnects or whatever...Unfortunately I made conclusions about the Lascala's limitations only to disprove that with another upgrade. I'm sure Lascalas do have their inherit foibles. Like in my yurt (a tent house) few speakers will be able to produce any impactful bass as their are no solid walls. Kinda like setting your speakers in an acoustically open field. SVS sub (SB2000 pro) cured that. My tube amp (Raven Blackhawk) has a soft hum which with Klipsch efficiency at 104 @ 1 watt can drive you crazy until Mad Scientist disks. Now the hum is barely detectable. (In between songs, at night) So if one hears about the nature of Klipsch horns remember, they are like spoiled women. They tell you everything they hate quick and yet can grant you an evening of euphoria you'll not soon forget!
