>>Take a 1.5 AA cell and two connecting leads; connect the + and - of the cell to the loudspeaker terminals; you'll hear a small "pop" and the bass driver will move slightly, either forward or backward. The drivers of both speakers should move in the same direction when the polarities are matched.
This is the procedure I've use many times, to check speakers. I usually
