Recommendation for a replacement speaker cable
The PTFE tubing can be found at McMaster-Carr for a good price. https://www.mcmaster.com/ptfe-tubing/high-temperature-tube-sleeving/ Thanks for the pointer to get the silver wire. - Jay |
anyone still following I stuck with the small diameter solid core concept, ended up with CAT8 22 awg x 8 = 13 awg pasted from the 16 ohm thread: I ordered everything for new DIY Speaker Cables COST: $136.44 incl tax & delivery ................................. CONNECTORS (spades and adapters at speaker’s back panel) .........................................................spades, pure copper 2 set screws 8 pcs CABLE: I ended up ordering a cat8 s/ftp (shielded, foiled twisted pairs) When you twist them you lose length, I need 12 ft straight x 2 = 24’ x 2 spkrs = 48lf straight, a roll of 50ft would be short. Speaker cables l/r should always be the same length (time of travel aligned, hah!). I chose this cable, ordered 10 m (33ft) red; 10m (33ft) black, each leg 16lf to make 12 ft: red/black twisted. https://www.ebay.com/itm/174307181712 22 awg, 8 solid (not stranded) OFC copper S/FTP construction = 13 awg This chart shows relative gauges, physical sizes, and resistance. https://www.rapidtables.com/calc/wire/wire-gauge-chart.html two basic choices cat gauges: largest 22 awg; smallest 26 awg 22 awg x 8 = 13 awg (+152% area above 26 26 awg x 8 = 17 awg (+152% resistance above 22 22 awg solid = less flexible is not an issue for me. .......................................... CONDUCTIVITY CHART https://www.bluesea.com/resources/108/Electrical_Conductivity_of_Materials silver is only a little more conductive than copper gold and aluminum are only a little less conductive than copper brass is a lot less conductive than copper COPPER TYPES (hard to verify true facts) often text says solid but diagram shows stranded; text says 23 awg, chart shows 26 awg, and seller’s answers are often not clear. https://www.thomasnet.com/articles/metals-metal-products/types-of-copper-wire/ ’Pure Copper’, (99.9% pure) often in text, with or without OFC is not in the above article, it is in this article, https://en.wikipedia.org/wiki/Oxygen-free_copper C11000 - also known as Electrolytic-Tough-Pitch (ETP). This is the most common copper. It is universal for electrical applications. ETP has a minimum conductivity rating of 100% IACS and is required to be 99.9% pure. It has 0.02% to 0.04% oxygen content (typical). ................................... L PADS will be disconnected, new + wire direct from crossover for both horns (one as a test first) ............................ WOOFERS, remove, check cones Picking these suckers up onto a low bench for the work is a job for two masked men. Recent MRI: I now have 4 herniated discs, one tear, pinched nerve. |
