RE: Raises some interesting points about phase/time coherence,

Speaker Asylum

General speaker questions for audio and home theater.

Fwiw, the Synergy horn approach both allows higher order passive crossovers but by passes the “all pass” phase response of filters higher than first order.
In addition (being less than ¼ wl apart) the different drivers add coherently into one new radiation, the polar patterns show a single source (no pattern of lobes and nulls) and on some Synergy horns the phase response is that of a single crossover less driver and so the net result is the opposite of the head vise effect.

With separate sources (most multi-way loudspeakers), that “flat phase / gd “ condition can be achieved with DSP, but only in one physical location and the sources continue to radiate a pattern of lobes and nulls (an interference pattern).
