Theaudiotweak...I didn't mention it before, but why should the amplifier care where the crossover network is located? Try hooking up the speaker with red and black wires reversed, so that the crossover is in the return leg. Does it sound any different? (Assuming that you have accounted for the inversion elsewhere in the system)
Having, as a DIY guy, played around with both series and parallel crossovers I don't see a performance advantage of one over the other. The series is more difficult to execute in practice (not harder to design), and we all have the gut feeling that if something is difficult to achieve it must be of great value. This is an opening for marketing. Actually, I like low level electronic crossovers, or, in the ideal, a full range speaker (where the crossover is mechanical in the form of cone breakup).
Vive la difference.
