I have magnets on both sides of the diaphragms and ribbons.

I also have push pull bass which one driver moves "forward" while the other moves "backwards" in a force cancellation configuration and linear fore/aft motion averaging.

Both +/- push and both +/- pull AT THE SAME TIME.

Both need the same electrical signals rendering the notion of "directional" wires nonsense.

The diaphragm moves in and out at the rate of instantaneous audio signal, each wire procides 1/2 of the complete audio signal. When electrons move toward the voice coil the electrons on the other wire move in the opposite direction. When electrons move away from the voice coil you can ignore, it. We only care about electrons moving toward the voice coil, they're the ones that make the diaphragm move. Follow?

  NOPE:
  + MAGNET PUSH --> VOICE_COIL--> PULL MAGNET
  - MAGNET PULL <--VOICE_COIL <-- PUSH MAGNET
  If what you are saying is true:
  Placing a DC battery on a speaker with correct polarity it will move forwards.
  If you put the same DC battery on in reverse polarity, the driver won't move backwards. That is NOT true.
  No voltage moves the driver to the center location.

    Of course the battery moves the diaphragm. It moves out and stays out. That's why two wires AC are needed for audio. The IN and OUT signals come in on different wires, + and - . The signal alternates on both + and - wires. It alternates at the instantaneous audio frequency. Electrons move only very slightly at one time in an AC circuit, about one millionth of an inch at a time.
