Responding to growing demand, AKG decided to produce the C 451 B model with the same acoustic performance as the popular C 451 EB + CK 1, with significantly improved specifications.
Using an extremely clear diaphragm, the C 451 B is almost completely insensitive to noise. The C451 B is an excellent microphone for picking up drums, percussion instruments, acoustic guitars or for ambient miking.
