RE: "A function of all the wire in the complete circuit, all at the same time"

We have have just discussed the electrons really aren't moving in the conductor, just a millionth of an inch at a time, on average. So in reality electrons in the fuse or cable or wherever upstream never advance beyond that point. Net velocity is zero. They just wiggle back and forth at audio frequency. The E field (and B field), on the other hand, is affected by all wire and cables upstream and is part and parcel of the Poynting vector, which is an electromagnetic wave. You haven't been paying attention to my last few posts. We're off electrons. They are a distraction, a red herring. It's the E field that is the "audio signal" not the electrons. The E and B fields contain the energy as has been pointed out, and are located entirely outside the conductor.

"It's the E field that is the "audio signal" not the electrons."

That is correct and that E field is affected by both wires. The wire going away from the speaker just as much as the wire going towards the speaker.

  But only one wire works at a time. When one wire is doing the work you can ignore the other wire and what's happening on it. That's why the direction of both wires matters. Are you about to have a breakthrough?

    It takes both wires or nothing happens.
    You have to understand that, don't you?

      As Randall McMurphy said in One Flew Over the Cuckoo's Nest after he failed to lift the 300 lbs water cooler by himself, at least I tried. Good luck in your quest for mediocrity.
