What about passive crossovers in the higher frequency range, above 1kHz or so?
I think the component values get smaller there, so it's easier to have inductance
and capacitance without too much side effects? Most tweeters have a lot of damping built in. And a passive highpass will automatically protect tweeters from DC...
