Agree with Jbehr. I always figured the reason for putting the tweeter out of phase was to cancel its response overlap with the woofer. Time aligned designs usually have some slant or tilt thing happening to place the tweeter farther away than the woofer.
Switching polarity of tweeter in two-way design
In order to align the time&phase of the tweeter to the woofer in a two-way design, is it a common practice to switch the polarity of the tweeter so that it is slightly delay in time? It would be similar to having the baffle slanted at a small angle.
I think it is done on the ProAc 2.5 and probably on some of the DIY two way speakers
