RE: Indeed - that's what I've used for 20 years! ...

But:

1. I use Belden 1595A - which is 'plenum rated' (so the individual solid strands are insulated with teflon not PVC. I strip off the blue PVC jacket.).

2. I don't do the ott braiding which early users popularised. I don't think it's necessary - you simply use as many twisted pairs as you think are required for the current drawn by the driver(s), for the length of the cable, and then you have 3 options for using the strands:

a. use the coloured strand in each twisted pair (tp) for '+ve' and the striped strand for '-ve'. This option gives you the lowest inductance - which is a good thing, in a spkr cable. But it does give the highest capacitance - which can upset some amplifiers if the spkr cable is long).

b. separate all the tps and use all the solid-colour wires for the '+ve' leg ... and all the striped wires for the '-ve' leg. Twist all the strands in '+ve' leg together ... and all the '-ve' strands together - so you end up with two separate cables.

This option gives you the lowest capacitance - which is a good thing for very long spkr cables (like 30' plus!) - but it does produce the highest inductance.

c. use equal numbers of tps for '+ve' and '-ve'. Twist all the pairs together (remembering which pairs you have allocated to '+ve' and which to '-ve'!).

This option is in the middle of the above two, in terms of 'L' and 'C'.
