Basic Q re: Active Cross-Overs

I'm still trying to figure out how to get the most out of my ML Prodigy speakers with a pair of ARC VT 100s. I'm bi-amping, but want to add in an active x-over to avoid wasting power on amplifying signals that just get cut out by the speaker cross-over...

ML indicates that the internal x-over in the Prodigy speakers is 250 Hz and makes a big deal about matching the x-over to blend the ESL panel and the woofer. Here's the dumb question...

To avoid messing with ML's careful balancing act, would using an active x-over like the Bryston 10B with the high pass filter set *above* the ML cross-over freq. (e.g., set at 300 Hz) and a low pass filter set *below* the ML cross-over freq. (e.g., set at 200 Hz) still provide significant benefits and still allow the ML magic to work?

Said another way, for the ESL panel, is it irrelevant from (other than a power perspective) where the active x-over low pass is set, as long as its set below where ML's x-over is, and vice-versa for the bottom end?
