There is no reason for a conjugate filter unless you are running a passive crossover. The main reason for a Zobel is to conjugate the inductance a speaker's voice coil, to counteract for its rising impedance. It is done to modify the behavior of the crossover and make the filter function of a passive crossover more pure.
With an active crossover, you don't want a Zobel on the speaker drivers. Connect them directly to the amp.
Here are some documents that describe electrical filters in more detail:
