using more than one preamp to create a crossover network is not that dissimilar to just using a crossover network. if that is what you were saying... ANYWAY, my point was that you need to control the sound going to the respective speakers (tweeter, mid, bass) and have NO crossover inside the speaker. it seems like you may know this already and just wanted some support for you decision to bi-amp. well i'm afraid that i dont always agree that bi-amping makes a speaker better. those speakers are probably older than i am, so i couldnt offer any insight into them.
