I'm not saying Wright's theory is correct.

His panels were in a one-meter-square box and I'd guess the origin of the spheric shape was maybe 10 feet back.

As for flat panels, yes there is beaming. But if you are sitting in the beam, what's the problem?

Geddes presents a good rationale about dispersion angle and tweeter horns. Yes, dispersion matters (but can be fixed as I said previously). It matters most when, like Geddes, you are manufacturing a speaker that has to work even in the homes of uninformed users.

Honestly I don't experience any more than with my Kappa 9s. Transition is more pronounced maybe, but so what? My Kef 105s have the smoothest most gradual transition but again, when it's gone, it's gone. I will stand by my position that sweet spots are always narrow as I define the term, to lose nothing.

I don't have a clue what you mean by any of those sentences. Perhaps the fault is mine.

I was referring to the beaming and the sharper transition from the sweet spot.
