Theaudiotweak...Unless the amp is bridged, or is one of the new digital amps, the output is unbalanced anyway, and I don't see how location of the crossover would affect it.
If you really think this is important it would be easy enough to split the crossover components between legs... for example: a 4 mH inductor could be implemented as two 2mH inductors. Such a crossover would look PERFECTLY symetrical in a schematic. You can't say that about a series crossover because either the woofer or the tweeter must "come first".
Actually I think all this is academic, and good crossovers (to the extent that any crossover is good) can be made either way.
