"I was immediately drawn to the sf16’s neofuturistic styling. Its gentle curves reminded me of the iconic TWA Flight Center at New York’s JFK Airport—an aeronautic theme sustained by wing-like sound pods that sprout on command. Unusual and unique."

IMHO, Bob Ankosko has his design taste in his butt.
Unusual, unique, and FUGLY is all I can think of when looking at that bug eyed looking thing.
Set it on the floor and drop a JBL M2 on it, then you'd have something to write about. LOL

I'm not sure where you draw the line between "using an important measurement as one of the design goals/decision making process" and "obsession."
Efficiency is quite an important attribute for speakers intended for large rooms/spaces. Maybe you think you can obtain the same results by simply sending four times as many watts at a less efficient speaker, for example, but most of the time you'll be wrong. If it was that easy, you'd see lots of small speakers capable of both deep bass and high volume. You don't.
So what exactly is it that matters to you in speaker selection? Efficiency and frequency response don't matter, so, the color of the veneer?
If you think you're hearing your speakers and not your room at low frequencies, you're just wrong. Your ears just don't work that way with long wavelengths. The two are inseparable at low frequencies.
That's oblivious to the actual market place. There are thousands of commercial speakers designed with specific boundary reinforcement in mind. Everything from towers/bookshelves that call for being a specific distance from the wall (many active speakers have specific adjustments for it), to speakers designed to be mounted on a wall, to speakers designed to be installed in a wall....
Not if the horn is wide enough....
And I would add, straight enough. Any bends in a horn and all bets are off. So, where shall we put that straight 20Hz horn.........

Amphion & Gradient have floorstanders with passive cardioid implementations.
While a 20Hz horn would be cool
we were only talking about needing it down to the point the directivity will fairly closely match the woofer. Lots of horn speakers can do that to below 1000 Hz. Curved horns can work OK for that.
I'm not convinced. Tannoy's tweeter is a horn, concentric with the woofer, crossing over at 1kHz, and that has problems integrating properly with a 12 or 15" woofer. The Decca horn tweeter was also quite a good device, but the systems they were used in struggled as 2 ways.While a 20Hz horn would be cool
Those of a certain age may remember the Goodmans Trebax and Midax horns. Those integrated pretty well with a 12" bass unit, albeit limited by the technology of the era. However, that resulted in a three way. Dropping the Midax really didn't work.

The absolute thickness is unimportant. For speakers of any form factor, the amount of fibrous damping required to treat air column resonances is proportionately similar. The resulting loss of vent efficiency is similar for short and tall speaker cabinets, depending on the volume portion occupied and such.
And again, with a tall cabinet come the options to break the chamber apart or placing woofers such that the modal coupling sums to a minimal value.
ME Geithain made cardioid speakers before D&D and makes them fully cardioid (down to 30 Hz). See https://www.me-geithain.de/en/rl-901k2.html for example:
https://www.me-geithain.de/en/me-804k.html or https://www.me-geithain.de/en/me-800k.html can be considered towers, I guess.

The highest profile speaker that does a pretty good job is probably the JBL M2 (15" woofer). The JBL 4722 (popular with home theater guys) does a pretty good job. And of course numerous DIY designs (for Tannoy fans, take a look at the DIYSG Vortex 12/15).
I'm not saying it's easy or the speaker will be aesthetically pleasing to all people, but it can be done with a good design.

Insisting that towers playing full range, or subs placed right next to or under the main speakers is an antiquated, sub optimal 2 channel belief of the past. Yes, placing subs near boundaries does give some free sensitivity that will keep distortion lower and increase output without additional power. A benefit no matter how you look at it. The main advantage of multiple subwoofers is being able to place them *away* from the main speakers in the optimal positions for a smooth, accurate, high fidelity frequency response. Again, the goal is high fidelity.

Geithains aren’t cardioid through the midrange, just bass.ME Geithain made cardioid speakers before D&D and makes them fully cardioid (down to 30 Hz). See https://www.me-geithain.de/en/rl-901k2.html for example:

They are slightly congested compared to the Kiis/8Cs.

Sure, but isn't the whole point of cardioid dispersion to avoid exciting room modes? If your dispersion is even, not being cardioid in the midrange isn't necessarily bad, as reflections will be tonally similar to the direct sound.
The stuff out of the front is still going to excite room modes, Dutch&Dutch used to make an 8M model , similar enclosure to the 8C but not cardioid and didn’t have the two rear bass drivers.
Apart from the bass extension the difference was the clearer , less congested midrange.

The 8C is cardioid from 100 Hz onwards, it does make sense that modes are tamed in that range; don't really the point here.
The MEG is from 30 to 250. At 250 Hz, the wavelength is still ~1.4 m, but this shouldn't excite "bigger" rooms too much (aren't most room fundamental resonances in the 20-200~250 Hz range?).
Did not realize they made the tower-equivalents, but given availability of all their stuff is poor in North America, don't think it's a realistic option sadly. Good to know it exists!
Interesting, no measurements though, couldn't find any availability mention either. Only price I could find was old and $24,500USD, they'd have to be doing something really special to justify that(or more).
I looked those up and they look nice, for sure, but again no measurements. Something I'd be curious about if they were ever measured, for sure.
A single sub will never work well. 2 subs should be placed in opposite corners which will significantly cancel modes, not either side of the main speakers.
Edit: or opposite mid wall.

Hmm, the audioholics guides(which are based on that AES paper, I think) suggest that for 2 subs, midwall(either front/back or left/right) is better than corners.
