"Geeze.... This just sounds like every rant I've ever seen from people who heard them in horrible rooms with lousy gear. "
I'm another who also reported finding the bass of the Kanta to be disappointing - overarm and disjointed. It was in a very good room, with room treatments (including tube traps) on very good gear. A monitor audio speaker, about the same size in an essentially identical room did not have these problems.
I also demoed various Focal speakers over the last two years,and did indeed find some of them a bit too bright. They have always had a "look at me" tweeter sound, every time I've ever encountered Focal speakers (which is a lot, in many different set ups).
I actually like the sound of some Focal speakers, especially their large models.
