Someone pointed me to Bang & Olufsen Uni-Phase xover design.  At least based on theory, the filter will be able to achieve 0 degree phase shift across the frequency band, hence the name Uni-Phase.  I have not seen the step response but the square waves all look very good - not too unlike that from a time-phase coherent/time-coincident design.

Unlike the Thiel or Vandersteen, though, the Uni-Phase uses 2nd order filters, not first order filters.  The advantage is 2nd order does not stress out the drivers as much as first order filter.

Happy Thanksgiving! All
