A dipole speaker is one designed such that the drivers fire in phase but in different directions (ie. QS8). A bipole speaker is designed so that the drivers (usually opposed outward to each other) fire out of phase. A few tidbits I've picked up on this board.

So, if the drivers in the M80 are wired in parallel it would be neither a bipole nor a dipole.
