The mount has magnets that allow the two mono mics to connect together transforming it into a stereo mic. The 4050 was developed from the critically acclaimed Coles 4040 capsule that features extended frequency response and high output making it a very versatile capsule.
The 4050 largely uses the same guts as the Coles 4040, so you’ll find extended frequency response of 20 Hz – 20 kHz, 300-ohm impedance and less than one percent distortion at 125 dB SPL
