A bi-wire audio cable system designed to reduce propagation velocity (V.sub.p) differentials between low and high frequencies within the audio band, by adjusting the resistive and capacitive components of the cables. By utilizing two cables, one for low frequencies and one for high frequencies, with different characteristics, the impedance of the cables can be configured to be relatively consistent across the audio spectrum, minimizing the change in V.sub.p, thereby increasing audio fidelity. The bi-wire audio system can include a first (e.g. high frequency) cable with a first plurality of insulated conductors having a first conductor gauge; and a second (e.g. low frequency) cable with a second plurality of insulated conductors having a second, larger conductor gauge. The cables can be connected together at an output of an amplifier, and can be connected to corresponding low and high frequency inputs of a speaker (e.g. a woofer and tweeter).
