Shakey,
I'm not really in the market for a single driver speaker; too many limitations and negatives. But I think that the wide-range + tweeter approach is a good one. That's essentially what my De Capo's and the various Tekton models seem to so. You get that coherence with the crossover out of the midrange's way, but you're not asking the main driver to do more than it can physically accomplish in the high end.
