The M30 from Earthworks is a cost effective measurement microphone intended for large and small room calibration. The ultra wide frequency response of 9Hz to 27kHz is flat throughout the entire spectrum and results in accurate room calibration using Smaart, MLSSA, SIMM and TEF based systems.
The small element yields an omni-directional pattern resulting in a wide pick up area at the front and sides of the microphone capsule.

Comments about Earthworks M30 - Measurement Microphone:
I was thinking what would be better...if buying a good measurement mic or a Phonic PAA3, fortunately this was the best option when using with any acoustic dedicated software for studio situations. If you are planning to buy the Phonic you should have in mind what kind of application you really need, like portability and fast real time spectrum analyzer.

Comments about Earthworks M30 - Measurement Microphone:
for the price nothing comes close. Is the professional industry standard, bulit like tank, calibration files avalaible which shows what a professional company Earthworks are. You get what you pay for but more. Why would you trust cheap mics with questionable responses. If you are serious about sound then M30 would be the best mic that would serve you for years to come.
