I will echo the sentiments of others who have use active crossovers to biamp Magnepan speakers. Up until their X.7 models, they were built to actively biamp by providing an external passive crossover box that could be bypassed.
I did this with my 3.3Rs and the difference was astounding. I don't think there can be a single rule here. It all depends on the quality of the passive crossover components relative to the active crossover you might obtain. If you have 2 good amps and don't want to trade those for one great one, it is definitely a good experiment. But you have to get a decent active crossover.
