I think it will probably work just fine. In this case, you'll be measuring impedance. The sensitivity of the speaker won't affect your tests. The main thing is the accuracy of the meter at different frequencies. Hand-held multimeters didn't do such a good job at measuring AC outside of a narrow range in the past, because they were really designed only for AC line voltage. But all the DVM's I've seen lately are pretty accurate across the audio band, at least the frequencies of interest for a test like this (bass to midbass). Be sure to get an accurate measurement of your test resistor, because it will set the reference.
