Didn't see a mention of this, but I have heard the reason for bi-wiring is not to increase the guage of wiring but to keep innercable frequency interference to a minimum. When a signal from your amp goes to the speaker it makes the speaker move. When a voice coil moves in a magnetic field it generates a back current that goes to the amp. Appearantly high and low frequencies behave differently in a conductor and dividing the wiring to the high and low drivers is of benefit (even though they meet at the amp terminals). It's not mentioned in your thread if your speakers have separate terminals for mids and highs. True bi-wiring is about running two sets of wires from the high and low terminals on your speaker back to the single amp terminal on your amp (not all companies design their speakers for this).
Depending on the make of wire, some manufactures recommend a double run for improved perfomance. OCOS speaker cable ( a coax design imported by Sumiko Corp.) is such an example. In this case, lower mid and bass are improved by a double run. This application essentially increases the amount of signal going to your speaker. While not a true bi-wire set up, this configuration does improve the sound. Fortunately OCOS is relatively affordable and I was able to do this. Cost can be significant if you're talking Nordost and the like. Sometimes the money is better spent using better cable instead of twice as much. Ya just gotta listen to it!
So bi-wiring is about the physics of two way traffic in a speaker wire between the amp and the speaker.
