Microphone Parts’ RK-47 capsule is based upon the Neumann K-47 capsule from–you guessed it!–the U-47 microphone. The RK-47 is ideal for U-47-inspired DIY projects or for modding existing microphones (see partial list of easily moddable mics below). RK-47 capsules are individually tested and delivered with their own frequency-response charts!

The graph above compares an MXL2006 stock (red) and the same mic with an RK-47 capsule (black).
