Hey Jack, IANAPCD (I Am Not a Passive Crossover Designer), but I suppose it would be accurate to say I am an active crossover designer. I don't know that it's accurate to say that a passive can do things an active can't, except perhaps for some impedance flattening (and that's of arguable value except in the HF). When you only have one amp channel available then yes, you need a passive crossover. But that's not technical ability, that's cost cutting.

Almost any DSP can do pretty much anything you'd want to be doing to a loudspeaker, but you need to pay at least a certain amount to get into that club. To be fair, if you asked me what the "crossover point" was on any of my tunings I'd have to look at a final acoustic measurement, what I put into the DSP would probably sound weird to you... of course, the best part is coming back to a tuning to discover that someone has "fixed" my "wrong" crossover points.
