Would it be fairly simple to use a active crossover with Marantz MA9S2 mono blocks on the LF & McIntosh on the HF of the Arrays without having to mess with the speaker crossovers? If so, to the people who know of such things, what would I need.

Since I have this gear (Mac is idle at the moment), I would like to investigate the possibilities. The system sounds great as is but I am always curious.

Thanks!
