Neumann KM184 #2168 (Used)

The KM 184 (cardioid) in particular has become the classic high-quality miniature microphone.

Although the KM 184 has the same capsule as the KM 84, the microphone differs slightly on the 0° frequency response: The KM 184 has a gentle rise at about 9 kHz, a characteristic that was introduced very successfully with the KM 140. The result is a tonal balance that is fresher and livelier when compared to the KM 84 with its flat frequency response in that band. This difference was achieved with just a slight change of the capsule’s rear opening, and is not due to resonances.
