Not as impressive as I had thought they were... And that was done just to get closer CTC?

Yeah, it's the vertical I would assume the worst in this case. This never works as intended (such high aspect ratio). Thank you!
In a square waveguide the vertical will improve to match the horizontal, and the diagonal will not improve much, if at all.
Actually, the diagonal can be better than both, H and V. Seen that many times in the simulations. Don't ask me how is that possible.

Isn't that about what one would expect an SEOS to perform like given the extreme asymmetry though?
Yes, lol. I may have had some willful ignorance towards their performance. When they came out there weren't many WG's that a consumer could buy, except maybe the QSCs. And all you would see were the horizontals, which were fine. But in hindsight, they were an overall lacking design.
The perform just fine if their design decisions are what you want, I just think the asymmetry is too extreme. And there still aren't any available alternatives really with the QSC out of production. Which is a shame as the 90 x 60 pattern seems more reasonable to me.
I have yet to see a waveguide such as 90 x 60 that is really 60 deg in any usable sense. Too often this means just a rising DI.

Show me.
Perhaps I could find some more illustrative example but this one I have at hand (I haven't done a rectangular WG in a long time): #2494Show me.
- Doesn't it have the best behaviour along the diagonal?
I could scale it down to 1" (it is 1.4" originally) but that would still be 298 x 257 x 96 mm. Is there anyone able to print that for testing?
Or what about 0.75" or 0.5"?
Maybe I would also increase the 'k' parameter of OS-SE. Now I usually make it slightly > 1 and didn't have this paramater at that time.

No, not at all, its DI is higher than any other direction, exactly as I would expect. Not what I want.
Do you mean one that actually reduces ceiling reflection levels throughout its whole band?I have yet to see a waveguide such as 90 x 60 that is really 60 deg in any usable sense.
Why? How much is it higher and what's wrong with that?
This is the same old argument - I want a flat DI, that device isn't.
Yes, one with a reasonably flat DI through the intended band.Do you mean one that actually reduces ceiling reflection levels throughout its whole band?

I'm pretty sure it is.This is the same old argument - I want a flat DI, that device isn't.
It can't be. All directions will have about the same DI at LF - they have to. So if the DI in one direction is higher than the others at HF then the total DI has to be rising.

I have a 1.4" bms 4594he if the throat match? I could print it maybe in quarter sections.
