as far as clear, however, is still open to me with how much power I should operate the whole. (clearly only so much that it does not consume) but purely theoretically the system runs normally with 2*100wrms, I then need in biamping mode 4×50, bitsl reserve 4×60 ? or as I assume 4×100, since the speakers each need the 100wrms on their frequency band.? possibly also for the theory 4×90. gruss
