Are there Geddes style OS for sale anywhere? I don't know enough to know exactly what I'm looking at when I see a round waveguide on PE.
I believe the closest you're going to get is a DDS ENG90. It's very close but not identical profile (more mouth-flare, I believe).
I made my own for 15" variants. I would not do it again, the work investment was significant. If I were designing something from scratch I'd look VERY closely at JBL 2384 and 2453H-SL. It's a relatively affordable combo that can work with relatively simple XO and has, most importantly, truly excellent performance, with near constant directivity and low distortion.

I have three or four of the QSC waveguides which are clearly oblate spheroidal.
Every once in a blue moon I'll put them on eBay and nobody buys them.
They're not in great shape; I've used them for a bunch of projects so there's nicks on them and glue on them.
I would happily put them in a box and ship them to anyone for $50. I need to check if I have three or four. I have at least three.

It's the QSC 000106-gp
JBL 2384
Reminds me of the original "unitized image control waveguide" that I made, from eighteen months ago, that eventually became this : "Unitized" Image Control Waveguide
