    :
    Direct control of each driver by each amp channel
    Simple and easier impedance loading on amp
    No parasitic power losses
    No loss of damping (driver control)
    Less likelihood of clipping with clipping limited to single driver
    Consistent crossover behavior regardless of power level or signal content
    Less loading on each amp with load divided among multiple amps
    Less distortion

    :

    Generally, the high signal streams require massive components of the frequencyseparating
    filters. These massive components inevitably cause distortions and
    phase shifts. To put it differently: Exactly because the original signal is being
    amplified before it reaches the crossover network, its components (resistors,
    spoolings, condensers, etc.) have to be quite voluminous to be capable to
    withstand the amperage. So, a strong signal hits strong resistances.
    Inescapably, this signal will be impaired and distorted.

    The most important specific deprivation caused by passive filters is the so-called
    damping factor. This factor indicates the precision with which an amplifier is able
    to control the movements of the membranes (of the drivers). A bad damping factor
    means that the amplifier is not capable of controlling (the vibrations of) the
    membrane(s) in an exact way. Distortions concerning the sound are inevitable. Up
    to date high-class amplifier achieve excellent damping factors, but the passive
    crossover network impairs this factor drastically. To put it simple: In passive
    loudspeakers, the frequency-separating filters are located in
    between the amplification and the driver units and necessarily cause
    a loss of precision with which the amp can control the drivers.
    The best (and therefore quite expensive) crossover networks available today can reduce this
    impairment but never avoid it. Even the best ones diminish the damping factor drastically,
    on average down to five (yes, 5!) percent of the original value!
