campo, if I were you, I definitely would consider soffit mount for this kind of serious large monitors. I haven't done it, but I always want to do it... The work itself would be simple, butI have to empty the room before doing it. Have you ever read soffit threads at Johnsayers?
No, but I agree that soffit mount is the one the best options. I tried to build looking future forward though I intend to try this at near field, It should have enough output for far field. I'd like to think that one day I will own a house where I can build a room specifically for my audio task's and pleasure. Soffit mount would definitely be the way to go.
I agree. Your component choice and design should do that well, I'm looking forward to seeing the progress and results. Soffit mount is a good idea.
I didn't try a mock directivity model for the horn...was more interested in if I could make a decent looking crossing. Looks ok I guess. With the low pass shelf to create a flat response on the 350hz tractrix and a 381hz 2nd order LR the excursion remains very low even near 115dbit peaks around 0.12mm....
This is the unequalized response I got for 350hz tractrix but I don't know how correct it is.

Hi Rob, wow, that is impressive response in the top octave! What CD is that?
Kind regards,

That Eminence is a nice little annular tweeter, though not exactly comparable to the 3" B&C.
It's a kind of BMS clone, apparently a rather good one

i had sort of the same goal as the op. i found some used TAD drivers locally, a pair of 4001 and a pair of 1601b, and put them back together with 5 cu. ft. cabs. i've been trying them out with the ports stuffed, but eventually i will add tuned ports, something in the 30-35 hz range.
minidsp nanodigi 2x8 outputs to 2 DACs, 2W SET for the high end, and a crown XLS 1502 on the woofers. 800 hz xover. the tube amp rolls off a ton on the high end, so i EQ'd most of the treble back in (though the 4001 still rolls off pretty strong at 15 khz, though i'm also using a no name 60x40 fiberglass horn, not the TAD design), and gave it a bass boost as well to taste. i'm getting basically full range playback from that setup: roll-off occurs right at 28 hz, as Fs would indicate, and i still have decent response down to 20hz. it doesn't rattle things the way a home theater sub will, but i like the bass response. i have to imagine the distortion is way lower, the 15s barely move.

This project has sidestepped so many times, going from brute PA looking folded TLS to avant guard wood tractrix horns.
I think the only solution is to order n pairs of drivers, build all n approaches, decide on best sounding then sell n-2 pairs of drivers

Where do you get elliptical from? I do not see any elliptical parts. These horns are classical radial type with straight side walls and possibly Tractrix function vertical wise. You would get the knows advantages of this type but also the well knows disadvantages like midrange narrowing or fingerprinting.
These radial horns look very nice and the price is also interesting. But I don't trust that throat geometry.
