FWIW, you cannot in fact say there is a "consensus" here or in audio in general that bi-amping is simply superior (active or passive).
Bi-amping has one theoretical disadvantage: the loss of coherency due to mixing two different amps with their unique sonic characteristics. There will always be freq-overlap of the two amps with any crossover. This is assuming different amps top and bottom, but as has been pointing out, that's the only way to do it unless you're just down on power.
I'm not saying that bi-amping isn't better in nine out of ten situations (though I'm not saying it is), just that you can't make a blanket that it's always better with this potential/theoretical weakness (which many feel is very real in practice).
