I currently have both vertical and horizontal. Bass amp, (semi) active xover, and dual amps bridged to mono (Plinius does this easily). Previous setup also had 3 chasis but the uppers were born monoblocks and it used the passive xover of the speakers and a DIY attenuator. The advantage of an active xover is that it allows you to get rid of the passive, parasitic cancers. Nothing to do with limiting the bandwidth going into the amps and whatever they "think". Before considering an active xover, consider the surgery on the speakers and whether the passive network can be approximated externally.
The limited success of either method of biamping only suggests how the complexities are misunderstood, general ignorance, or a lack of patience. Some might say, "if you gotta ask, don't ..." , but that takes all the pain from learning.
Whether a stereo amp can or should be bridged to monoblock is dependant on the construction and the speaker load. Apparently, few should and much of the point is moot if the amps are already balanced (differential).
I agree with Steve that bridging is preferable, if available. If he says it would be good with your speakers, go for it. Often, the output wattage is quadrupled. Many speakers have the crossover point way too high to have any advantage for passive biamping.
Good luck
