Confession: When I built the mid-treble crossovers for my MG-IIIa's, I paid careful attention to the inductor orientation with the inside wire going to the "more positive" terminal and also set them orthogonal to each other. However while I know which end is up, I seriously doubt that the crossover knows. The signal is AC and the designation of plus and minus of the terminals is arbitrary and could just as well been red and black or flick and flack.
There may be a difference with caps in an amplifier as the the ends are at different potentials but this is not true with a crossover -- at least this is so with my setup where the amps are balanced and the "negative" terminals are not tied to ground.

You are then claiming that absolute phase is acoustically unimportant, since that is what "flick and flack" determine.
The flick and flack help us get the polariy correct and this is very important. As you well know, phase and polarity are not the same thing but are related in that changing polarity rotates the phase 180 degrees. As for me, absolute phase is a irrelevant but that may not be true for everyone. Some people are afflicted with the ability to discern absolute phase. Fortunately, I ain't one of them. In any case, flipping the ends of the caps and coils in a crossover has nothing to do with phase or polarity.
