Are these the ones?
My wife even thinks they're beautiful, which is more or less a mandate to build a pair of Bill's newest horns (as planned) and give them a similar look.

Bills designs: link? Or the design on page 1 of this thread. What's the best larger design out there?

I think he means the Small Syns. But neither this thread nor the Small Syns are large designs. They are meant be be relatively small

I'm wondering if there is another solution: what if you would take the simple 2-way design that is proposed here, and make it an acoustic resistance box by making some stuffed slots in the side panels. That would also take care of the lower down directivity, but does not need a box that is much wider or higher than the horn itself is.

I went with a big conical horn, a single 12PE32 12" driver for 110-500, entering near the throat in a 180 sq. cm. port. The cone throat is 25sq.cm area.

Did some tests with:
- Faital Pro 3Fe25 as full range. Not enough highs.
- Faital Pro 3Fe25 + Seas 27TDC tweeter suspended in center of the horn mouth. Sound was good.
- Faital Pro 3Fe25 + BMS 4524 in a OS horn. Sound is even better.
- today I bought the SB Acoustic SB65WBAC25-4. I will try it as fullrange, I want a simple 2way.

For subwoofers, I have sealed box but sometime I feel they don't integrate good with the horn loaded mid-bass. I am assembling a TH with B&C 10CL51 now, in simulation it looks good.

Not sure of what you had in mind but a made a foam Trynergy with woofer rear cone output going out a slightly damped open back. Bass was quite nice.

Presenting the Trynergy - a full range tractrix synergy.

A TH is a good idea for powerful bass. The hardest part is getting it to gonhigh enogh to cross with horn at 120Hz or so. A front loaded bass horn is better here as can go up to 300Hz easy.

Yes, something like that. Did you do polars of that one? In my idea the dampend holes would be on the sides though.

That sounds a little like my synergy experiment:

Yes, that is what I mean. Looks like pretty good pattern control up to almost 90 deg over the whole band.

That looks pretty nice, Onni. What kind of efficiency did you get in the bass?
Did you make a pair or just the one?
