If coherence is truly your biggest point, then you may be better off looking into the idea of designing and building your own speakers. If you are willing to look at something open baffle, then your degree of difficulty will be reduced dramatically - no enclosed box to design, calculate for and try to build...OB can be done much more simply and inexpensively.
But, if you’re looking seriously at coherence then you’d also in fact have to rule out passive crossovers. They can really do a number on the entire crossover zone. They spoil stage coherence, dynamic coherence (by robbing lots of power from the amps) and also tonal coherence which can affect things like clarity, timbre and vocal sibilance and intelligibility.
You will need active crossovers, digital are best...standalone active crossovers that use passive parts are too limited to be of any real value. But Behringer DQX, or Crown XTi-2 amps or the DEQX with the amps of your choice And a good conditioning solution that works for you and you can have real coherence that few other systems are capable of even at many times the cost.
I’ve done all this myself. I went with the Crowns and a buttload of Alan Maher Designs to completely tame the (mostly) digital noise and - presto, it’s all to die for.
Oh, and for wide dispersion you might want to consider excellent quality dome tweeter designs (beryllium??) rather than ribbons. Ribbons may have better detail usually, but they may also tend to beam a bit more than cones or domes.
