Hey guys,
sorry I had some (offline) quality time with my family.
I try to catch up with your questions:
Yes, we will publish our full Klippel NFS measurements, but there is still some fine tuning happening right now (also our lead engineer has two weeks off).
As for the two cardioids modes the difference is between "the null(s)", that means the space were the sound energy is being cancelled. In the "regular" (super)cardioid mode it's 180°, so exactly at the back of the speaker. Within "hypercardioid" mode it' on apx. 135° on both sides, which might work better if being positioned in corners (two walls).
Here is a preview of the NFS measurement that plat a polar, so a view from above the speaker at 360°. So here you can see 8super)cardioid @316Hz:

And so here is the hypercardioid (but @422 Hz)
View attachment 71131
Thanks!
Yes they can be placed very closed to a wall, of course you might do some room EQ depending on the situation.
As for narrow room – one of our showroom is only 3m wide, which equals almost 10ft, so about the same. Because to M1s constant directivity behavior there are only "good reflections" also from the sides. But you might prefer a "less livelier" sound, which means absorbing the first reflection points on the sides – it's a matter of taste at this point.
Right, D&D 8C – an excellent speaker by the way – is one or even two categories bigger, which translates into more bass (physics: more internal volume + more displacement + more amping).
Right, it's an fully active and digital design, just with the electronics offboard. There is only a six-core cable to link with each speaker.
Well, M2 is basically a scaled-up version of M1, as a floor standing box and will come with even more directivity modes. It uses the same tweeter but a 10" mid bass driver (closed). There is a hefty 12" at the back in a ported cabinet, so expect a lot of SPL down to 30 Hz (more than D&D 8C or Kii Audio BXT).
M2 will also have a wide baffle which is 48 cm (apx. 19"), but also very flat (< 20 cm / <8") – so really M1's proportions scaled-up. We found the WAF (woman acceptance factor) very high, because it looks more like a nice piece of furniture and not like a traditional speaker.
