Now that's what I'm talking about! The OS-SE may still be superior, but aesthetically the rollback Tritonia is going to blend into the average living space better. (imo)
As I said before, paint it the same colour as the wall, tuck it into the corner, and your significant other may not even notice it's there. (Maybe that's a stretch)

Only a coarse calculation for now (still took over 1 hour) -
Ignoring the obvious numerical issues, it's probably not bad.

Well it seems it will be pretty flat just on about any axis. Are we looking at the same pictures? In this case it doesn't really matter if it's normalized to 0, 10 or 20 deg (IIRC it was 15 before, I'm not sure).
The second picture is without normalization (i.e. constant acceleration drive).
I'm quite sure something could be done about the narrowing around 1 kHz but this non-axisymmetric optimization is a real PITA.

When taking Fluids findings into account, is it far fetched to assume that the Tritonia in a minimally sized baffle with appropriate roundovers should perform similarly? Of course with the drawback of this only being the case for three quarters of its dimension. The interaction with the baffle below and the woofer in it will certainly make things worse. But how much?
A while back Marcel showed that the lip of the roundover ending where it does makes a difference, verses one that goes all the way back and around like a cabinet. I believe it was one of the most interesting things to come of this discussion thread.
It was also succinct when he said recently that sound waves don't always behave the way that we would intuitively expect... (paraphrase)
I've been on the fence about what I want to build for few months. I'm very much leaning towards this freestanding Tritonia... Thinking of going big ~500mm

It's the later (except that I am not talking about asymmetry, only a continuous shape.) The rectangular waveguide will have severe problems along the diagonal, an elliptical won't. So in the H & V planes they are probably comparable, but along the diagonal they are not, but nobody ever looks at the diagonal response - I have, they get worse along the diagonal.
Do you really think that I don't know this? I know that I mentioned the desirability of the most gradual curvature to the baffle very early on in this thread. I've know this for a long time. Regardless of the final slope there is always a smooth 2nd derivative (curvature) that fits the conditions. I am still not convinced of your argument.
But you can avoid the flat spots, I did this in a prototype. The curvature just varies out to the edge no matter where the edge is. That prototype was not a resounding success, yielding some benefits and some new aberrations - a very typical trial and error experience, not 100% advantageous.

Or put the speakers behind a curtain like I do. I have never understood peoples need to "see" "pretty" loudspeakers. Make them right, ugly or not and just hide them!!
Right, I remember that. I suppose the question is how much of a real world difference it will make. The bigger drawback of a baffled wg is certainly the baffle and woofer below.
The latter aside, if one would route the entire baffle (from say MDF) the rollback could also be done the same as freestanding and not 'just' a standard roundover. Then the difference is really just the termination at the end or lack thereof.
It seems clear to me that free standing is best, but it looks like the performance doesn't suffer too much when the waveguide is integrated properly into a baffle. That just opens up more speaker design possibilities without too much of an acoustic compromise.
The baffle / woofer below is still a problem though.
