Active crossovers

Hey all. I'm currently working on an active 3 way system and wondering if and what options are available. The plan is a tri-amped configuration with a Behringer crossover but my question is whether there is such a thing as an electronic crossover that does not require multiple amps. Finding or designing a suitable passive crossover is far beyond my means and in my humble opinion they are a dinosaur anyway. I have three amps ready to go but having the option of just one would be the ultimate versatility. Thoughts? Thank you.
