Rich, bi-wiring(sometimes referred to as "buy-wiring") is pretty much all con. It means using two speaker wires instead of one from the amp to a speaker, which can be done if the speaker has separate input terminals for the woofer and the tweeter. There's no advantage to the procedure and no electrical difference except that using two wires is the same in resistance as using one wire three gauge numbers heavier(e.g. two 16 gauge wires equals one of 13 gauge), so it's a waste of time and money. An analysis of the setup can be found

heres a discussion of some interest, not because it repeats obvious facts, but because it's a cable company electing to not go along with the myth.
