I don't know, but I am bi-wiring my Legacy Focus SE's with two pairs of stereo speaker cables (took the jumpers out) and it sounds great (smoother and tighter in the bass). I think it's a bit more musical as well.
The interesting thing is that the single-crystal cryo-treated copper wire and dielectric material for each pair is the same, but the pair going to the mids and highs is a lighter gauge and costs about half the price of the pair feeding the woofer sections. I'm using 6' runs.
