Ideally, this is done using an active crossover between the preamp and the amplifiers, so that each amp "sees" only the frequencies it will be driving.
I may be mistaken here, but isn’t the net effect of this and bi-wiring the same? My understanding is that bi-amping connects one pair of terminals at the amp end along four lengths of wire, connecting to four terminals at the speaker end ...Yes, you are mistaken. In a two-channel system, biamping uses two stereo amplifiers (or four monoblocs), with a separate amplifier channel used for each LF and HF section of each speaker system.
