If you set the ohm meter to the lowest scale and test an operational woofer, you should get a DC resistance of a couple of ohms. Measure the driver with it disconnected from the crossover to eliminate any influence it might have. You will also generally see the speaker cone move slightly and give a sound when you touch the meter leads to the connections. (This may vary with the meter's design.)
If the resistance is very high (thousand of ohms or higher) you probably have an open or burned out voice coil and the speaker will need replacement. If you get a reading that indicates the voice coil is working (especially if you also get a noise) then you can start looking at the crossover or other internal wiring in the box.
