The Wunder Audio CM50 Tube Microphone comes with a small omnidirectional transducer mounted on a 40 mm diameter Lucite sphere. “Simply one of the most wonderful sounding room mics in the world,” the CM50 represents the pinnacle of quality in a revered line of microphones that stretches back to the very earliest days of pro audio. The inspiration is classic, the execution is cutting-edge. We have successfully recreated the small pressure transducer (similar to the capsule for the KM series microphones).
