Probably, TTBOMK the original dates from Bell Lab's early 1900s research. Here's the latest version of the musical instrument chart that went with it.

It looks like I have started the thread almost 10 years ago.
The question was really about supertweeters, and tweeters crossed very high to a wide range mid. It is usually a non-issue with subs and mid to woofer xo because the wl at xo point is usually large enough.
I have no new wisdom regarding the original question.
But I have been experimenting on the effect of CTC distancing recently (rather the effect of lowering xo point with fixed CTC). Using DSP of course.
Test bed was a two way with large-ish planar (neo8s) and a 15" midwoofer.
I tried xo points from 800 down to 300hz. And the image got better and better; the tightness and stability of the center image improved at every step without any collapse in the size of the total sound stage.
Putting a mid driver btw T and W does not solve the problem. Total height of the driver column is also important. Ie Your T to W distance also needs to be as close as possible (1/4 wl is probably a good guide)
Hence I purchased a coaxial driver for my next project 😊
