Loudspeaker Cables: Recommended Gauges and Lengths.Included is my latest thinking about wire and gauges, as well as some new tips and more photos to make fabrication somewhat easier. It's been awhile since the last major revision, so I've rewritten this entire article in order to clear up the patch-work of updates, fix the broken links, and straighten out some bits of contradictory information. We also sell a full range of pure silver wire with Teflon® jacketing by the foot or by the meter for DIY projects. Don't have time for DIY? Please visit Tempo Electric, our commercial sister site, where we fabricate custom interconnects, speaker cables, and power cords for only a modest increase above the cost of materials.
