ABSTRACT

It would be somewhat off-topic to go into a lot more detail about loudspeaker cable design, but this might be a good place to point out that there is absolutely nothing magical or mysterious about them. My findings [3] are that, looking at the amplifier-cable-loudspeaker system as a whole, the amplifier and cable impedances have the following effects:

• Frequency response variation due to the cable resistance forming the upper arm of a potential divider with the loudspeaker load as the lower arm. The effect of the resistive component from the amplifier output impedance is usually negligible with a solid-state design, but this is unlikely to be the case for valve amplifiers. This is at least potentially audible and is a good reason for using thick cables. It is not a good reason for using anything other than ordinary copper cable.
