This provides better headroom 3db if using identical amps, and if using vertical biamping one channel on woofer, one on tweeter, you see much better channel separation, as you will have one amp completely. The only difference in this case is that you run 2 signals to each speaker, instead of ruuning just one signal with a biwire cable from one speaker pair a or b and then.
At its root, bi means two, and it relates particularly to the axiom m80ti and m60ti tower speakers, which are supplied with biwiring terminals.

Biwiring uses just one channel of amplification to power the same type of speaker. In initial research we where open to the possibility that biwiring could potentially lead to better sound, since our multiconductor cable design easily facilitates such configuration. The bass has more energy than the treble, so a lower power amp will work for the mids and highs. For example, if biwiring with two sets of 12 g wire, use 9 g.
