Bi-amping can work very well when done right, but where most bass rigs are concerned it's done wrong. The wrong way is using full range bass cabs for both amps. The right way is with an electronic crossover that sends the lows to a dedicated low frequency cab, say a 1x18 or 2x15, the mids and highs to a dedicated midrange/HF cab, loaded with six or eight inch midrange drivers. A variation is using a bass amp and bass cab for the lows and clean mids, a guitar combo for overdriven tones, but that's not bi-amping, it's dual amping.

I was hoping you'd chip in BFM. Back in the day I did a bastardised version of what you suggest, as I split my signal, then used a crossover into an amp driving an SWR 410 (with tweeter off) for the lows and another driving an old Peavey 215 (no tweeter) for the highs+fx. For some reason that sounded better/more musical to me. I think I might have stolen the idea off switching the 410/215 from Billy Sheehan.
Without going into too much detail, I tried some crossover trickery on my full range cabs today and it sounded awful, your comments on full range thus reaffirm my findings.
What if I turn the tweeter off on one and the tweeter on full whack n the other.... hmmm....
On a different note, remember the Trace 1x18, 410 and hi-box 4x5 set-ups of back in the day? Back breakers that sounded great
