Wonderful stuff. When I was reading all the typical 'sounds great' comments at first I thought yeah right here we go again. Because we all know an awful lot of guys get sucked into whatever's new and flashy and more often than not it turns out merely different, maybe not even better. It was only when I started seeing comments like 'draws me in' and not just detail and clarity but adding very natural, at ease, not at all fatiguing, etc that gets my interest. Best was some guy said his wife has her friend listen to Stevie Nicks and she's moved to tears. Audiophiles can talk themselves into anything but women? One woman playing music for another and they're crying???! Home run!
Tweeter crossed over high makes total sense. After all, they all are tweeters. But at a high enough frequency the wavelength becomes short relative to the driver. I'm not a speaker designer and don't know the math but if the wavelength is much longer than the driver then you can have a whole bunch of them and they all seem to be one source. That's how the array works. But at high enough frequency the wave is short relative to the tweeter and then if all of them were driven it would smear the imaging.
When I do the math for a roughly 1" tweeter the wavelength works out to a frequency of about 8 to 11kHz. So yeah pretty high.
I don't know about your speakers but am told the one on the Moab is crossed over down around 300 Hz, with meaningful output another octave below that. So with a super fast tweeter midrange array handling everything from 300 to 10kHz - and an effectively co-axial tweeter- no wonder it sounds so good!
