I think in this case it's phase inversion of one of the signals as opposed to a phase shift which would imply a time difference.

- mbell 14y agoThere is no phase inversion here. When the signals are the same there is just no voltage across the speaker. Think of it as putting 5 volts on both sides of the speaker, the voltage difference from one side of the speaker to the other is 0 volts, so no current flows and the speaker is at rest.
