I'm not familiar with Martin Logan crossovers, but you may well need to remove all or certain components of your speakers' internal crossover if you go to "active biamping" with an external crossover. Check with the manufacturer and see what they advise.
Good luck ... I haven't done this myself yet, but if you use a good external crossover "active bi-amping is supposed to be an terrific way to go . BIG gains in clarity and effective power from your existing amps.
