I guess there are many mic specs that could be the target of 'testing' a mic.
I was going to try and cross-check my two reference mics for starters. They are ok at the calibrator frequency for both expected signal level of the fundamental, and show the same harmonic structure of the calibrator, so that's a start. It may be easiest to just close mic a woofer, then a tweeter, and compare responses, and hopefully they are both the same (otherwise I won't know which mic is NQR). Hopefully I can get a valid measurement over a fair audible bandwidth, as the mic specs go well beyond what I can set up - even if I can get a good comparison over say 200Hz to 5kHz then that would give me confidence that the response would be to spec.
