The M23R is a precision engineered 23kHz omnidirectional measurement microphone ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required.

Infinitely Matched
Every M23R has the same frequency response and sensitivity – matched to within +/- 0.5dB across the entire operating frequency range (3Hz to 23kHz).
