another polarity riddle


forgive me for raising this venerable topic again, but...

i recently bought a pair of audiopax 88s to power my avantgarde duo 2.0s. the audiopax amps invert absolute polarity, so i have attached + to - on the taps of each amp. so far so good. the crossover of the AGs apparently also inverts polarity, so that it i recommended that the jumper is attached + to - from the mid horn to the treble horn. now i'm confused. wont following this advice negate the polarity shift from the amps -- at least as to the treble horn -- or does the crossover in the mid horn take care of this. thanks for any guidance.

thank for the detailed response. yes, the avantgarde duo 2.0 inverts polarity in the crossover to the treble horn. the newer omega upgrade features a crossover that maintains polarity. dont ask me why they would do it that way. the good news is that i have followed your advice and it sounds fantastic. i apprecite the help.
If you have access to a spectrum analyser, when playing white noise it will show a deep notch at the crossover frequency if the drivers are out of phase.
My Jadis amp inverts polarity - the manual asks to switch + and - in the speakercable at the amp side to solve the issue - now my AG UNOs invert polarity again, so I decided to keep the cables at the amp side with + and - correctly attached. I do notice a better resolution and laid back presentation with this configuration rather than than following the continuous polarity changes along my setup.
