What good does bi-wiring do?
Once the crossovers have been electrically separated, they present different impedance (loads) to the power amp within their passbands and outside of their passbands. The woofer and corresponding low frequency crossover section will present a low impedance at low frequencies and a high impedance at HF, while the tweeter section will present a low impedance at high frequencies, and high one at LF’s. One argument about bi wiring is any improvement in the sound is due to the decreased total resistance of the cable, and this makes the speaker less prone to frequency response variations due to cable resistance. According to this view, simply running the two cables in parallel at both ends will do the same thing. With the electrical separation, differing currents will flow within the two cables that make up a bi-wire set. For the separate cable feeding the woofer section, a lot of current will flow at LF’s but not much current at HF’s, and the tweeter cable will have some current flow at HF,
Some say that any improvement in the sound it makes is strictly due to the decreased total DCR, and this makes the speaker less prone to frequency response variations due to cable resistance. According to this view, simply running the two cables in parallel at both ends will do the same thing. In my opinion, this is a very simplistic and incomplete way of looking at the situation.
