The electrical phase of the woofer has nothing to do with its physical orientation. The net acoustic phase at the listening position is affected by the relative distance of the drivers from the listener at the crossover frequency. Unless the path length difference between woofer and midrange is greater that 1/4 wavelength at the crossover frequency, it's of negligible consequence to the acoustic phase. And if it is greater than 1/4 wavelength, then the designer has taken it into account when he designed the crossover.
