Q, you're a day late and a dollar short. I tried to watch the original video but it said I had to register so i didn't watch it. I'm not that up on electronics to know what a speaker looks like. I thought that was some magnetic coil. Usually the container has some holes for the sound to escape and I didn't see any. As for a solid handle, that doesn't mean you don't align it with the target and feel/sense the Lenz effect, but I guess you wouldn't know because you are blind to the truth aka ignorant.
