Shure RPM106 Cartridge for SM7B, SM7A and SM7

The factory replacement dynamic cartridge for the Shure SM7B, SM7A, and original SM7 microphones. Installing a fresh RPM106 restores the flat, wide-range frequency response these microphones are known for, keeping reproduction of music and speech clean and natural. A practical repair path for broadcast studios, podcast rooms, and recording facilities that want to return a well-used SM7 series mic to spec rather than replace it.
