Is it possible just to use the ICBM as a 2 channel crossover? I have a prologic Yamaha RX-v870 feeding 2 outboard amps into my Mirage M-3si speakers, and i also have a 230L sealed Tempest that i'm trying to seamlessly blend in. It seems like the M-3si play low enough to where the subwoofer clashes with it and muddies up the bass. I want to cut the output at 65hz on the mirages and direct the rest to the Tempest. Will the ICBM do this for me or will i have to look at another active crossover, or possibly the ACI passive filters, how are those??
