Wellllllllllllllll , that says all that one needs to know about those speakers ...To my surprise, I found no measurement results published neither on Spatial Audio website nor on their forum at AudioCircle. Frankly, I cannot believe Clayton does not measure his designs "playing it by ear" instead so to speak...

The words are mine. I am certainly not a Guru in the field, but I imagine any competent designer (and Clayton certainly is) does measure his designs thoroughly. What is intriguing me is the fact I was unable to find the measurement results published... I quite liked the X5 model: 8 Ohms nominal, 97 dB sensitivity (easy to drive with my small PASS amp), goes down to 25 Hz (!). Outstanding! BUT why, oh why, can't we see the actual measurements?!Are those your words or Clayton's?

Thank you Duke!
I'll likely never buy a speaker for which I can't find CEA-2034 (or something comparable), and I'm much more likely to purchase from those who provide the measurement results themselves. High chance, in my mind, that companies who don't publish the data themselves do so because they know it would paint them in a poor light.
Just my take…
The M3 and M5 Sapphire at least have a very unusual concept.
A (modified?) 1.25'' tweeter from Peerless taking over at 575Hz with a second order high pass. Even with 32mm voice coil, that's brave.
This is definitely a very interesting tweeter from Peerless.
It says on the product page "Crossoverless Dome Midrange/treble Driver", but then in a review it says that capacitors are used to protect the tweeter, which is of course a crossover
There are probably no measurements because the frequency range above 1-2kHz radiation may not be very uniform. Below that it should be pretty good but, as @peanuts already said, will require EQ.
no way a passive dipole like that will measure good.
they need eq, all of them.
