    With that I think I misunderstood the beginnings of the thread. I always assumed the radial center of the speaker would be the point one would measure to, regardless of where the sound originates. For some reason I took the original question to mean the center of the voice coil behind the cone. Your explanation makes far more sense to me. Thanks for that.

    Ask yourself this...

    WHERE does the electrical impulse become a mechanical movement?

    Some use the VC former/cone joint.
    True, but say you energized a VC with a suspension but no cone, would you hear anything? If the VC was on a 2-foot former would the sound originate from two feet behind the cone?

    I bet some impulse measurements would solve this pretty easily.

    But the finger doesn't make the sound. Does the bow of a violin make the sound? Of course not. Same thing with a guitar or a speaker.

    I have friends that have a collection of like 3 bows, worth more than my house. It's pretty damn important
