I would say, in a typical combination of direct-radiating woofer and horned tweeter, designed with the goal of good transient response, group delay of hipass is around half of the one of lopass. Looking at plots of the original post, you see phase difference between lo- and hipass belo cross-over point. Therefore one may use two woofers embracing one tweeter, as Joe D'Appolito suggested. As frequencies go even lower, phase difference matters less, as hipass amplitude is fading.

I favour a second-order lo- and a first-order hipass, and then, as frequencies go even higher, phase difference between hi- and lopass shows up, too, but again one branch becomes that quiet, that the cross-over works.
