It would seem that there is a relationship between higher efficiency speaker's dynamic range and the benefits of an active crossover system, and multiple amps.

Could anyone care to comment.

Thank you in advance.

I would say that, in essence, if you are concerned about efficiency then power losses through passive crossovers are best avoided.

The reason to go active is mostly for the amp, not the speakers. There are other things that come into play because of the reactive nature of the loudspeaker load, but the main thing is the bandwidth reduction of each amp. Reduced bandwidth helps keep 'em from clipping. The less you have HF modulated by LF, the more dynamic range you can get from the amp before hitting the power rails.
