Well...

If you reduce everything to nodes...

Thing is, the resistance really isn't the most interesting feature, even though theoretically there is basically half of it. Half of zero... right. Still half. What's neat is the ability to choose where the current divides up. What many people overlook is that the current flowing in the high-pass filter's "feeder" conductors is different than the current flowing in the low-pass filters "feeder" conductors, by virtue of the different transfer functions (impedance against frequency) of each filter/driver combination.

If the total current produced by the amp is I(total) then you can write:

I(total) = I(hp) + I(lp)

In the single wire case, the currents divide up after the jumper, which is at the binding posts of the speaker. In the bi-wire case, the currents also divide up after the jumper, except now the jumper is effectively at the amp.

Here's an idea. You can use a cable that is great for bass because it has very low resistance and lots of copper and it's great for maintaining damping factor, and you can also use a cable that is not as good for bass, but perhaps excels at high frequencies - such as fine wires or ribbon cables. The ability to bi-wire allows the user to use different cables for the high and low sections, "optimizing" each one, and resulting in far more iterative possibilities. What audiophile could resist?

Now try passive bi-amping with identical amps and identical cables. The current flowing in each AMP is now dedicated.

Now try passive bi-amping using different (gain matched) amps but one that has incredible bass power and the other one has a more refined high end, despite being somewhat too polite...

Now imagine two CD players and two DACs and two pre-amps. You press play on both DACs simultaneously. You could "bifurcate" your entire signal chain, even the source material...

I find it interesting that bi-wiring is not as often ridiculed as passive bi-amping. If anything, passive bi-amping is less of an insult to "all too common common sense" because by virtue of having two amps you now NEED two cables.

Then again, those who protest bi-wiring tend to ignore than when the current to each respective filter/driver combo divides up at the amp, so do the magnetic fields that exist along the length of the cable. You're not just separating the currents, you're putting the magnetic fields for each respective filter/driver combo in different places in physical space.

Hmmm.
