We match Mini K87s to 0.5dB in sensitivity (measured at 1kHz), and about 1.5dB in frequency response, 50Hz–15kHz. Acoustic testing is done at Roswell HQ in northern California. The matching procedure uses a calibrated, proprietary low-diffraction speaker to produce a swept sine wave, which we record with each Mini K87 to measure both sensitivity and frequency response. Each microphone is also auditioned by Roswell staff as a part of our rigorous QC process.

Each microphone includes our exclusive Cutaway™ metal-frame shockmount (with spare elastics). Matched pairs ship in a single stereo-pair aluminum flightcase, which holds two microphones and two shockmounts.
