Based on a quick read, yes, these are "hybrid" crossover speakers. Meaning, they have an external crossover that does the crossover between the woofers and the rest of the system.
Each section requires 1 amplifier channel. There would also be a passive crossover as well, between the tweeter and midrange.
You need 2 channels of amplification per speaker. One for the woofers and one for the mid/tweet section.
