Audio Research made both active and passive crossovers for bi- and tri-amping Magneplanars back in the day.
If you see one for sale today, it is tons of money since, obviously, some people still want to bi- and/or tri-amp their systems.
While the technically descriptive articles above are interesting, if one wishes to use an active or passive crossover to manage their system, I see little reason why this cannot be done.
We set up many systems with these crossovers in the signal path back in the day, and they had no detrimental audible influence on the music. Possibly that is why these items remain both elusive and expensive today.
Cheers!
