With two drivers you turn one forwards and the other backwards and the one facing backwards is wired out of phase (-+ instead of +-). So both drivers move in the same direction at the same time (in phase). The reason is because if the driver motion is non symmetric (it moves differently forwards than backwards), then having one driver face forwards and the other backwards cancels out this source of distortion.
Three is an odd choice. Driven by the needs of more surface area versus the inconvenience of four?
