Didn't put this on full range forum as I'd want to cross around 2khz - the only drivers I can find that are a close match are from Visaton and ESS. Wd like to end up with a true 92+ dB sensitivity and f3 of around 45hz if possible. Large box size is fine
AE TD10M maybe? I crossed mine to a WG at about 1k7 and the Fs is down around 40Hz with a Qts of 0.26 according to the specs. I ran mine as mid so I didn't bother confirming TS.
Nearest I can find is this: Audax PR240MO
Not sure if they'd work in a 2-way with that 2.8khz peak though...

Not that i know of.......
10" 92db. F3 sealed 45hz.
That's skirting hoffman's iron law.
B102 92db 2ft3 tuned @ fs @ 50hz ported.

I've got some brand new, boxed Eminence B102's in the shed if anyone wants them (Cheltenham, UK).
The Tekton Lore uses the same driver in about 59ltr.

including baffle step compensation? 🤔 that's tough!
maybe LAVOCE SSF102.40 comes near (but lower sensitivity)?
or SSF102.50L (91,5 dB but higher f3)?
edit: however, both are not at all "fullrange" ...
Folded horn.
Is there a reason for that level of sensitivity? Amplifiers are cheap.
1K crossover. Crossing to a horn?

the closest i get is the Faital 10RS350, that is 91dB sensitive but fit all other requirements (not fullrange but high enough in flat response). But like said, it's hitting hoffman law's border limits... If you can crossover lower more is possible.
Closest I cd find was B200, which is 95db before bsc. 120 litre (wide baffle) will get mid 40 f3.
But when I looked at graph, most of that high efficiency was in the midband..
Very true.........
Loudness of the driver at 200hz is more fair than averaging to 1/2 its peaks.

60L could get you there. I don't have a driver suggestion though.
Sensitivity is one thing, though I refer to efficiency on the below chart.

Is there any particular reason you are looking for full range driver when you are crossing at 2kHz?
Can look at SB acoustic ceramic and metal cones or for that matter any of their 8-10" woofer. They typically go to about 10kHz...

Audio nirvana reckon their super 10 has 96db sensitivity, but I've seen people say their specs aren't always accurate
I recently came across these and think they look pretty interesting.

No experience with them but they seem to meet all your requirements. BUT... with 1.8mm of xmax they will be power/SPL limited. Looks like 100db is possible with 7-8watts. Do you like it loud?

Just seen this thread on the home page. https://www.diyaudio.com/community/threads/new-sba-8-full-range-driver.357933/
The Misco driver does not have much magnet. 1.8 mmxmax seems likely for 94 db efficiency and 567 gram ferrite magnet.
How about this driver : https://audioxpress.com/article/test-bench-dayton-audio-pm220-8-wideband-neodymium-8-woofer
