Anybody out there bi-amping with a high powered environment? I'm curious what the *correct* setup is concerning preamp, electronic crossover and a pair of power heads. My reason for asking is that passive crossover networks capable of dealing with 1000w and higher will be difficult and/or expensive to come by. The capacitors alone are $31 each, and I need more than half a dozen for each of two cabinets. It seems to be cheaper and more flexible to bi-amp the bass drivers and mid-ranges separately, and do the frequency division in the low power preamp stage.
