Both the MMC2006 and MMC2011 encapsulate two opposite-facing 4060 omnidirectional miniature diaphragms to form a single-capsule, twin-diaphragm design, which reduces noise while enhancing sensitivity.
The omnidirectional MMC2006 offers a frequency range of 20 Hz to 20 kHz with a soft roll-off below 50 Hz and typical 3 dB soft boost at 14 kHz, ± 2 dB. The cardioid MMC2011 capsule is a pressure gradient type with interference tube, offering an exceptionally flat frequency range of 20 Hz to 20 kHz with a 3 dB soft boost at 12 kHz, ± 2 dB, at 30 cm.
