I think it's mostly the room > lots of reverberation.
Noam Geller posted a video of the Lansing Iconics.
From the first notes onwards... I think he's right. This sounds natural.
I built pelnty PA speaker with BMS drivers (1", 1,4" and Coax). I think I know what you are speaking about.
The BMS tend to sound "soft" - at least at pretty high power levels (so not in the living room - 1000pax room). Not weak - but a great 2" shows you more precise what's going on on the stage. The BMS sounds more "HiFi" - which is often pretty nice. I thought the very high K2 at high frequencies is probably a reason for that.
My last project was with the B&C DE360 - 1" ring radiator which goes without resonance to 20kHz (but starts right after there). It's membrane is way harder as what BMS is using and I also had the impression of a more detailed, "realistic" sound. But still without metal dome "ringing" and a relaxed presentation.
But I didn't A/B them so this is really just a guess! Don't take it to serious.
There are some conflicting aspects to PA design compared to Hi-Fi though. For example the lower efficiency could be due to increased use of disipative surrounds and back chamber absorption which would improve fidelity. Also a Hi-Fi design could use a smaller gap between the phase plug and dome and a larger back chamber as it doesn't have to be designed to be thermaly limited rather than excursion limited over its full range as a PA driver normally is. TBH I also think classical compression driver design is that complicated, especialy if you accept less than the maximum possible output in the form factor.
I'll give you three current products that would qualify as "cream of the crop" out of the box:
TAD TD-2002 (1" throat)
TAD TD-4001 (2" throat)
GT SOUND GSU-D04R (2" throat)
Horns:
Yamamoto SS-500 (1" throat)
Yamamoto SS-300 (2" throat)
I'll let others summarise on the "reasonably priced" options (none of which I can guarantee will be as good as the above).
is it the Kartesian CMP45 ?

Anyone tried ND3ST?
Distortion test from Voice Coil is so low, maybe the lowest I've seen at 104dB.

CSD plot shows a bit resonance though.

i had the NSD3N ( nitrided titanium version) with a JABO KH53 horn very good combo from 800Hz flat without correction but needed a tweeter from 10K with this large horn.

Yap. It is really the only reason to go back to Munich next year, kind of pathetic.
very nice!
BTW should I dare ask what you thought of the Klipsch Jubilees?
You go first...
The two systems were physically identical except that the crossover component values were tweaked to yield as close a FR as possible.
These two systems were then rated virtually identical. Both of these systems were rated higher than two other non-identical systems.
These results are what led me to the belief that drivers make little to no difference - it's all in the system design, not the drivers.
very nice!

The worst sound of the show. Embarassingly bad.
Very nice! Do you know of any modern, say below $500, that comes close? 🙂
