This new top of the line microphone has exceptional performance.


What's the flattest response mic?

The Earthworks QTC50 is speced +/-2dB 3HZ-50kHz. DPA 4006 +/-2dB 15Hz-20kHz. Maybe DPA or B&K has other mics (smaller capsules) that are flatter? Also I would think a small figure of eight mic has the flattest possible power response. /Peter
