      Comments about Earthworks M23 - Measurement Microphone:

      Used every day as an integral part of our acoustical alignment/calibration tool set in a major postproduction facility.
      This is an outstanding instrumentation microphone.
      Slightly disappointed however that the manufacturer's ".frd" calibration file is not included in the cost.
