Core size and stranding Speaker cables need a particular mention as they do affect the sound of loudspeakers. This is because cable has capacitance,
resistance and inductance that will react with the capacitive, inductive and resistive elements of the speaker crossover and
speaker drivers. The thicker the gauge of copper, the more strands and the better the insulation of the cable, the better the
speaker will behave as these combine to allow the amplifier to get more
immediate control over the speaker components by raising its damping factor.The human ear is immensely sensitive to phase inaccuracies. This is because although we hear up to 20kHz, in order to pinpoint sources of sound to the accuracy we do, our brains discriminate phase timing displacements between the ears in the realm of around 500kHz. (This is also explains why we 'hear' jitter). The dielectric material can have a large influence on phase linearity. [read more]. |

Not only do fine strand cores give much better phase and high frequency precision, they are flexible and long lasting. Thick strands
cost less but are not as flexible or long lasting and are prone to loss of phase detail due to the loss of energy
as electro-magnetically induced vibration between strands. Speakers require a cable gauge appropriate to their current draw – the manufacturers should recommend a gauge. However, the cable gauge must be increased as the distance between the speaker and amplifier gets larger. |
