The speaker wire loss study page: https://www.kn5l.net/SpeakerWire/ is updated with #22 measurement and model. A good demonstration of vinyl RF absorption. The larger #18 speaker wire with greater vinyl content results with an increased loss over #22 speaker wire. Where the #18 vinyl loss is

There were some comments about speaker loss and the contribution of loss as a result of vinyl dielectric. A way to evaluate is to measure a length of speaker wire and compare to an air dielectric equivalent. Here is an example: https://www.kn5l.net/SpeakerWire/ The Air dielectric equivalent
