Earthworks M23 Condenser Gooseneck Measurement Microphone Up to 23kHz
The M23 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.
The M Series has become the accepted standard for affordable, reliable reference and measurement microphones that are accurate in the time domain and frequency response. They are remarkably stable with respect to temperature and atmospheric conditions and are optimized for clean, very fast impulse performance providing accurate wideband response with virtually no handling noise.
Unparalleled Audio Results at an Affordable Cost
A flat frequency response that extends from 3Hz to 23kHz, an exceptionally consistent omnidirectional polar response, 140dB SPL rating without distortion and no handling noise.
Consistent Measurements in Any Location
Immune to most temperature and atmospheric fluctuations, the M23 delivers reliable and repeatable results in any environment.
Professional products
designed with professionals in mind
In audio, our perception of what feels real and natural is incredibly sensitive to resolution in the time domain. In particular, the level of detail present in the initial transient is responsible for much of our sense of content, meaning, and frequency balance. This includes defining attributes like “timbre”, “texture”, and “air”. Earthworks’ blazingly fast technology ensures that every performance sounds like life
