Michael,When I started telling people that the fibers in a TL don't move, everybody rained on my idea. Since the early 70's the JAES articles all said the fibers move. Almost everybody said I was a quack and the forum "experts" ridiculed me and my MathCad worksheet approach to transmission line speaker design. Times have changed.
You never know unless you try and most forum "experts" are anything but,
