[QUOTE="ThxOne, post: 8703709, member: 675210"] Please understand that I am not saying the author of that article is in any way stupid. I agree that there is a massive amount of knowledge there.

The cone or diaphragm is what moves the air in front of it.... The moving air is how sound is made and it is coming from the movement of the cone or diaphragm. Without either of those items (cone or diaphragm) the air would not move enough to make sound. You would literally have a voice coil moving in and out of a magnetic field... in near silence. One could argue that without the voice coil there would be no movement to make the sound but this also is not true... you don't even need a "voice coil." [/QUOTE]
