In spite of the fact that the Blessed Neville has recently published a
paper on complex passive crossovers that work well, active boxes allow
the use of low-level crossovers that are much easier (and cheaper) to
design (especially if you aren't the Blessed Neville) and implement, and
allow the drivers' movements to be well controlled, by eliminating any
*significant* upward excursions of the driving impedance due to the
passive filter. ('Significant' means more than about a tenth of the
driver impedance, not 0.00001 ohms!)
