i realise that bi-amping is used primarily to get a cleaner, clearer sound, particularly if your cab isn't handling the low-end well, however i don't consider this an as improvement to tone, because its more like a correction of a cabinet flaw. nobody seems to have discussed its effect on tone. ok lets say we've got 2 rigs: * RIG1 - a 2X10 cab + a 4X10 cab non-biamped and you've got no problems producing the the full spectrum of frequencies * RIG2 - a 1X15 cab + a 4X10 cab biamped and assume that you've got no problems with it like a hole in the frequency spectrum or powering each of the cabs etc. etc and you've picked a crossover frequency that you're happy with ok, assume that they've both been setup without problems and each of the cabs are made from the same manufacturer (including the drivers). which rig would produce better tone? or would they sound about the same?
