It's pretty easy to measure the low frequency response of omni microphone capsules. You only need a small woofer mounted in a small enclosure. There needs to be a sealed hole to connect to the capsule. For a typical electret capsule the whole thing can be placed inside the enclosure. The resonant frequency of the woofer should move above 100 Hz. The pressure inside the enclosure should be constant below the resonant frequency.You only need to have an oscillator that goes down and a meter that goes to the lowest frequencies of interest.

Do you really still believe the manufacturer's specs?
