In biwiring, both sets of wires going to the separate terminals have exactly the same signals, not separate signals (high frequency and low frequency) as implied by Shawn's post. Bywiring simply increases the effective size of the conductor to the speaker and bypasses the speaker's binding posts' interconnection. Some claim that this makes a difference.
help with biwiring
I've been trying to figure out how biwiring works, I understand two duplicate amplified channels are feeding the upper and lower sections on the speaker, but where do you get two left or right line levels to amplify separately? Is the signal simply split into two wires between the preamp outputs and the amp. Basic question, I know, but sometimes they stump me the worst.
