There are some "active crossovers" made by such companies as Rane and Behringer. I've been looking into this option vs a passive crossover if I try a DIY project(tower speakers). I'm most intrigued by the Behringer crossover so far, esp the Ultradrive Pro which is upgradeable and can create virtually any type of crossover. This combined with 3 modest amps like the A500's and you're on your way...
