Help me with a speaker cable build, Ideas?

Audio sensibility, Take 5 audio, parts connexion, Audiyo, VH labs, and many others, for high grade audio oriented cables, in bulk (by the foot).

This tends to be better money spent, when it comes to trying out making your own cables.

It is not unusual to try it yourself first, and to do it using anything but ’high end audio’ specific bulk cable.

But, in the end, the audio specific bulk cable designs, do turn out to be the best money spent in DIY speaker cables. And interconnects. Have fun along the way....

Actually, in my experience, there is one other. One cable design to rule all the DIY cables. Copper foil from the stained glass industry, with stabilized physical geometry and insulation supplied by simple high grade paper based masking tape. It is the most DIY of all, but it has the highest value return.

The big trick, is, if one finds the copper foil cable as being deficient in some parameter.. it is generally not the fault of the copper foil - the fault lies elsewhere in the system. This can take some time to figure out.

It is like walking up a set of high end audio steps. The foil gets you one step up in the right direction, and then another leg has to move to a new spot. The foil is already correctly positioned to provide lift upward, via other or connected effort. The foil is not a misstep. In many systems, it may not be likened to a misstep or 'the weakest link' for quite some time, in the realm of sequentially attempting those upward steps.

Various thickness, widths, and backing materials.

All copper these days is inherently 99.99% OFC copper. As the cheapest way of making it is via a electrolytic process that automatically comes to that level and type of quality. They would make it cheaper if they could but that is now the bottom of the barrel in copper quality, strictly due to costs.

Basically, you lay out a long strip of high quality masking tape, on a linoleum kitchen floor or whatnot,..done glue side up...and then lay down a long strip of the given copper of the right ’total guage/area...’, of equivalence to 18-14g or whatnot..and then a strip beside it, separated...and then lay another strip of the tape down on that, using the glue side down, so the two glue sides contact and entrap the copper strips.

Thus you get a high grade high current high bandwidth foil speaker pair set, for about $40 total. With paper dielectric, no less, which is a very high quality dielectric. the glue sucks, but you can’t have everything. Maybe even multiple strips of copper per positive and negative leg. The good part of the glued together set is that it is low mass with high damping. The ideal desirable combination. With an almost MIA dielectric skin. Which is also desirable.

You can even make unshielded interconnects of the thinner copper foil, via similar techniques. And you can probably run video signals down the speaker cable version they are so high bandwidth. Or alternatively run a toaster at 1400 watts.
