Right click the directivity plot and choose polar map. Right click on the impedance plot and choose directivity chart. Right click on the impedance plot and choose polar map.
You have changed 'Y' for the crossover. The polar map will show this difference now, even if you don't measure at many angles.

No it doesn't. But my bet is that the more point source, the better image. I see a true point source as the "grail"- yes hyper smooth, even, 360 omni. I will attempt to build a pair in one way I haven't tried yet 🙂 - with a big nod to Amar. But there is a distinct difference between the HornFlower and my corner floor2ceiling line sources for sure - that are since a few days at the same location for the first time. Advantage HF.
Sorry for the OT - the mod started it ;-D

Remind me not to take you anywhere 😉
I suspect that for the few different points you just made there is a more circumstantial explanation, sometimes more than one.. but carry on.

I feel now I might probably have misunderstood you or written something offending. I don't grasp the gist of "Remind me..." - sorry for my limited language skills. For the rest of #24 I cant tie the comments to what I wrote in #23. Sorry again and I hope you didn't found the "mod" comment insulting in any way...

Here is the simulations for the xover. (think i mixed them up before, my head was spinning after a long day)
Named Polar 1 is just the xover with our settings.
Polar 1 inverted tweeter, is the same but with inverted tweeter.
Polar 2 is the same BUT with all drivers unmuted.
Polar 3 is the same but with 24 dB on midrange insted of 12 dB (as polar 1)
Can you see something on this polars ?
For me its just like a rainbow but not as pretty.

Y should be set for the drivers and off axis vertical measurements included would put the project into reality.
x,y and z should be set. The tweeter is set to 0,0,0.

As you speaker don't have a flat baffle, you also should set z. ("depth")
X=0 is Ok as all are on a vertical line on the baffle.
