Earthworks M23 23kHz Omnidirectional Measurement Microphone
Brand
Earthworks Audio
Looking for precise, laboratory-grade accuracy when tuning sound systems, designing speakers, or measuring room acoustics? The Earthworks M23 is an industry-standard omnidirectional reference measurement microphone engineered for seamless integration with SMAART, Room EQ Wizard (REW), SpectraFOO, and TEF alignment software.
Achieve absolute acoustic measurement accuracy, reliable flat frequency response, and laboratory-grade precision with the Earthworks M23 Measurement Microphone. Designed for professional acoustic testing, room correction, loudspeaker design, and live sound system tuning, this high-definition free-field condenser microphone delivers dependable, uncompromised performance where absolute data integrity is required.
Why Choose the Earthworks M23 Measurement Microphone?
Acoustic analysis tools are only as reliable as the microphones feeding them. Standard microphones introduce phase anomalies and off-axis coloration that can distort calibration curves and skew tuning results. The Earthworks M23 eliminates these variables by combining a near-perfect omnidirectional polar pattern with an exceptionally smooth, wide frequency response. It behaves consistently across all angles, ensuring your acoustic software and real-time analyzers capture the true, uncolored behavior of the physical space.
Key Performance Features
- Certified Frequency Response: Provides an ultra-flat frequency response from 3Hz up to 23kHz, ensuring comprehensive coverage across the entire audible spectrum and beyond.
- Near-Perfect Omnidirectional Pattern: Delivers true 360-degree pickup consistency, ensuring accurate sound pressure level capture regardless of microphone orientation.
- Lightning-Fast Impulse Response: Swiftly tracks rapid acoustic transients and impulse tests with zero time-smearing or lag.
- High SPL Capability: Safely handles up to 140 dB SPL, allowing direct measurement in front of high-output loudspeakers or loud sound reinforcement rigs.
- Extremely Stable Temperature Performance: Built to maintain precise calibration tolerances despite fluctuations in ambient temperature and humidity.
- Rugged Stainless Steel Build: Precision-machined from high-grade stainless steel to survive the rigorous daily demands of touring audio engineers and field technicians.
