THE BEST AUDIO SPEAKER

It's sexy and cheap lol.

not sure how eddy currents are involved as that is talking about magnetic fields... maybe you are thinking about the "skin effect".

Skin effect is straight up propaganda... at the amperage levels you are talking about, the entire conductor is saturated regardless of strand count.

Would love to see the results of resistance test on 15ft of 1/0awg car audio cable vs that of 1/0awg welding cable... It'd take some might expensive equipment to measure any difference from the two electrically... and who knows, the welding cable might just win. Like I said... welding cable is UL certified, it actually has to meet standards.


Cheap? Car audio wire is usually 50% to 100% more than welding cable of the same awg. The real reason you buy it is cause it's sexy.

The separate conductors act similar the laminated cores of transformers to help prevent eddy currents.

As for skin effect, it is a very real thing, I promise. We use air/foam core cables at work because it helps eliminate it. The skin effect only starts happening at much higher frequencies than audio, so unless someone is using power cable to transmit RF, skin effect isn't going to be happening on the power cable.
