Description
Precise acoustical work demands a microphone that tells the truth, and the Earthworks M23 was engineered for exactly that. This omnidirectional small-diaphragm condenser delivers a ruler-flat frequency response extending to 23kHz — the spec that gives the M23 its name — so what you measure is what’s actually happening in the room, not a colored approximation.
Because the M23 captures sound evenly from all directions with minimal deviation across its response curve, it’s a natural fit for demanding technical applications rather than creative tracking. Sold here as a matched pair, these mics are especially valuable when you need two verified-consistent measurement points at once.
- Room acoustics analysis and correction
- Sound system calibration and troubleshooting
- Loudspeaker design, development, and quality control
- Any application requiring an accurate free-field measurement microphone
If your work involves diagnosing a space, verifying a system, or validating loudspeaker performance, the M23’s omnidirectional pickup and extended high-frequency response give you the transparent, dependable data you need — with a matched pair ensuring both mics behave identically for comparative or multi-point measurements.
