Also, I understand from Dave that the added baffle thickness won't matter significantly in terms of the relationship of the driver with the enclosure... it'll be + the additional thickness further out from the enclosure volume.
More care might be taken with the internal chamfer around the opening I expect.
And remember the volume adjustments if including the recommended internal bracing as indicated on the plan variations. .

Yes. Sort of. But only as midTweeters. Both our WAW use A7.3eN in an aperiodic midTL. A quarterwave instead of a half-wave line thou.

Width is a major factor in where the transition from 2∏ to 4∏ steriradian radiation happens.

I found these standard designs on the website.
I like the big one with adding some bracing here and there.

Those are all Dr Scott’s (@Scottmoose) sketches. Haven’t done proper drawings of any of thow yet.

Still, for the size of the Lhotse, its Fb48/F6-40 does not match what the Sibelius can do @Fb38/F6-36
That's because
a/ It isn't meant to in the first place, and
b/ MAOP 11 can't get as low as the modified 2nd generation Alpair 10 variation Peal use (not in these types of enclosures). Sadly, try as I might, I've yet to be able to break the laws of physics. 😉

Pleasure. 🙂
No secrets, no sauces, just engineering. LF load characteristics are dominated by Fs, Vas and effective Qts' (where Qts' = Qts + any series R in circuit from components, wire, connections or the result of amplifier output impedance), so they set practical limits on the kind of alignment that is achievable with a given driver & enclosure type. Within those are then sub-sets of enclosures, and of course different design goals for different examples. Lhotse for e.g. is designed as a [relatively] low-forced MLTL, with the cabinet providing a larger portion of damping around Fb & a more modest duct length / CSA ratio relative to some more highly forced (smaller) types, hence the fact that it's taller than many. And so on & so forth.

Note that ignoring A12pw, A10.2 had the lowest potential bass of any MA. A10.3 traded that for greater sensitivity and better mid/top.
