I use active bi-amping which is the use of an electronic crossover BEFORE the amps. The signal is split into highs and lows before the amps. Passive bi-amping does not split the signal and therefore no electronic crossover is needed, nor is any alteration of the speakers needed.
With active bi-amping the speakers crossovers must then be altered. My set up was designed for me by Dan D'Agostino of Krell fame.
In addition to removing the low pass filter from my bass section, he determined that I also needed to change the polarity, as the speaker designer reversed the phase in the bass section with relation to the min/highs for passive use. (this is not an uncommon practice)
Also the mid/high section of the crossover also was altered.
The electronic crossover board was also designed by him.
Because of him, not me, my system was done right.
Good luck,
Richard
