Stumbled on this , they are obscenely expensive but any intrest in discussing the open air design concept ?

Looks like taking a full range panel and making it a multi way open back problem. Hard to see how it is good unless doing tons of EQ. Which would make it likely inefficient. Would solve the problem of being a big capacitor for the amp.

I believe it is called open baffle and dipole as well.
A big (retired now) proponent: http://www.linkwitzlab.com/LX521/LX521_4.htm
A hybrid (midrange is open baffle) https://dutchdutch.com/8c

They do seem to be embracing DSP.

Too small a baffle = insufficient bass. Now you need to start EQing, not always pretty. In the right room (large) OBs done right can be very nice.
Open baffle can be done inexpensively, don't scoff. I am doing a 5.1.2 atmos system with OB center, surround and overhead speakers. I have had the center with 2-8's, 2-6.5's and tweeter hit down into the 50hz range with room gain. It was only about an $85 investment. There is alot of info online and with Parts Express inexpensive driver assortment, it is a fun experiment.

Everyone says it is important that a box speaker should have uniform dispersion at all frequencies because it is important that the reverberant sound is derived from the same sound character as the direct.
But for some reason they are happy for 'out-of-the-box' speakers to have the weirdest reverberant characteristics you can imagine in frequency, phase, timing - including the inverted waveform reflecting off the front wall.
With all such speakers, the listener can hear the nausea-inducing weirdness especially when they move their head or shift position. They are a triumph of wishful thinking and hardware fetishism over the simple, straightforward, basic requirements for a true loudspeaker (that are not necessarily fully achievable, but are a giant step closer if you use a box).

Well, toss Quads on the ash-heap of history, then.
I'd kill for a pair of '63s... They still sound more like live music to me than anything else I've heard. I must admit I never experienced "nausea-inducing weirdness especially when they move their head or shift position" with them.
Very quiet live music...

What do they do that a modern DSP-ed box speaker can't do?
I've listened to a couple of Open Baffle loudspeakers, not seen any measurements, but then they don't measure like conventional forward-firing loudspeakers, so possibly no point.
In a very large room, they work quite well, but:-
No better than conventional loudspeakers.
They require vast amounts of EQ and consequently amplifier power and consequently driver power handling and excursion capability.
It makes me ask the question:- Why? What's the point, what's the benefit? It just seems to me a way of being different for the sake of being different and to have something at home that's a talking point when people visit.

Not have a ton of time and phase distortion.
From the review you linked, where do you get very quiet?
Have you owned or listened to 63s? Have you ever heard 57s stacked with subs? Have you lived with any 57s? Quads are very special speakers, yes, somewhat limited dynamically (max volume) but do so much right that the tradeoff was worth it.
