Thanks for the detailed response.Yes. The 'cutting edge design' not just deviates from common wisdom, but it frankly contradicts any established 'good practice'

This is, assumably, intended. It renders the speaker most sensitive to room placement. It sounds different, of course, in any place.
The philosophy reminds me of experiments with square wheels on a car. It has been done. Yes, it adds a lot of drama and excitement to the experience of driving. But would anybody choose such for daily commuting?
Same here. I can tell, because I often had failed designs on my bench. Namely my own DIY stuff, doing it for decades. These errors don't sound too bad for about a day or two. But then, hmm, nasty it appears more and more. Would anybody, after the purchase of a 10k speaker pair admit the wrong decision?
My advice would be to stay away from 'alternative wisdom' in speaker design, how fancy it may appear. Better stick to standards like Neuman 120A for 800$ each, active, digital. That would spare tons of cash for other excitements like sky diving, scuba diving, a yacht even. Let alone the music.
I’d just like to point out that my question which you picked up on, was referring to DanielT’s post above yours that referred to the Alexx, and not your post at all - I habn’t seen yours at the time!
