Mo, I was trying to just briefly summarize several points, and I wasn't referring to the small amount of the wave energy which penetrates into the conductor to latch onto the copper electrons for guiding the wave down the outside of the wire and is lost as heat. The reference was to the majority of the wave that remains outside the wire and actually carries the power and information to the speaker. This was discussed here in some detail a couple of times with links to technical info explaining how energy transmission along wires actually works, compared to the irrelevant water-in-a-pipe analogy sometimes seen.
