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.
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.
