Actually, this depends on a few other factors than just crossover frequency and configuration. Just as important is driver position in respect to depth. It's a matter of distance to the listener in terms of wavelength in the crossover region.

The polarity is reversed this way on the midhorn/tweeter crossover of six, seven and eight π speakers, which use a single coil (pseudo) first-order filter on the mid driver and a third-order on the tweeter. It is not reversed on the Pro four π, which also uses a single coil on the midwoofer and a third-order on the tweeter. Both have a 1.6kHz crossover, but on the six, seven and eight π speaker, the mid is further from the listener. On the Pro four π, the tweeter is further than the midwoofer.
