Here is the easiet way to tell. Use a battery...9v is usually easy to use. Cut the plug on the back of the speaker while leaving around 2" of wire. Connect one wire to the positive terminal and one to the negative. The speaker will "pop" if it moves outward the speaker is in phase. If it is in phase check which wire went to the positive terminal and that is your positive wire. If the speaker moved inward then it is out of phase. Reverse the two wires on the battery and that will tell you the positive.
