More powerful amp for top or bottom?

Meiwan...Can you please explain the types of problems that could arise from that great a difference of output power. Also the types of problems from using different amp manufacturers. I'll probably end up with a very similar situation so any advise is appreciated.

Bass definitely requires more power. However, it is almost impossible for both of these amps to increase in volume in a neartly exact fashion. Even if you find a good match at 10 watts, was volume increases one amp may increase at a different rate.

Strangely enough, when I was bi-amping Maggie 20.1's, sound was best with more power on treble and mids. Never would have expected that...

Tyler makes active speakers. Could you go that route. Give him a call

Even though both amps must cover the full voltage swing, since the impedance into the low frequencies will be extremely high due to the internal crossover, it will be putting out very little current and therefore very little power at low frequencies. Ultimately, the real nswer is try it both ways, and see which souunds best.
