Keep in mind that any apparent difference in levels may NOT be found at 60hz if the speakers mid or mid/tweet is not 'right' or the same between speakers.
Even though the meter SHOULD be pretty good at 60hz, it'll read at higher frequencies, too, but not accurately. I'd say it SHOULD be fairly repeatable, so you'll at least be able to COMPARE side-to-side.
If you have access to MEASURED impedance data for your speaker, it may also be possible to computer POWER using ohms law. You might be able to get the same data using multiple meters measuring voltage AND current at the same time. But i've never tried that, so am on less stable ground.
Too much is never enough
