Are the ohms on all the speakers the same?

Whenever I'm done wiring a cabinet I always double check my work to make sure I didn't mess anything up, I just stick a speaker cable in the jack of the cab and take a multimeter set to the lowest ohms setting, touch the neutral to the jacket and the positive to the tip. That way I always know for sure everything is good to go.

thats what im gonna do!plug the multimeter and check all the things but if the connection for the ohm are all ok with this kind of switch can the phase of speaker be inverted? thanks a lot.
