Assume a single wide-range driver actively high-passed with a 24db L-R filter placed directly above a single subwoofer low-passed with the same slope at the same frequency. Allow for both drivers to hover at ear level several feet away from any walls and adjust gain levels for a correct summed response.
As the subwoofer is moved closer to the floor, to either side, or front to back, what would be the effects on the summed output (disregarding increased localization with distance)? Could offsets along a particular axis be fixed simply by adjusting the gain? Would movement in any direction require phase or delay compensation? Is there any condition where filter frequencies would need to shift relative to one another to allow for more overlap?
I'm trying to wrap my head around the different ways subwoofer placement can affect crossover cohesion and any responses would be very much appreciated.

Movement of the sub closer to a corner or floor will increase level.
Movement of the sub away from the listener will decrease level.
As long as the driver distance to the listener remains within 1/4 wavelength at the crossover frequency, phase (and delay) don't need adjustment, assuming the sub and top were time/phase aligned to start with.
