A switchable wire includes filaments, each of which includes a heat-activated material layer that may be indirectly heated to change its state between different states having different electrical conductivity. In an example embodiment the indirect heating may be electrically resistance heating by passing electrical current through an electrically-resistive core of the filament. The heat passing through an electrically-insulative coating around the core, and into a heat-activated material layer around the electrically-insulative coating. The heat-activated material may be a chalcogenide material that is shiftable between a crystalline electrically-conducting state and an amorphous electrically-insulating state. The state of the material may be controlled by controlling the heating profile through controlling heating in the core. Many such filaments may be twisted together to form a switchable wire. Such wires may be used in any of a variety of devices where switchable electrical conductivity is desired.

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).
