RK-12 Microphone Capsule

$79.00

The RK-12 is an edge-terminated capsule designed to be a replica of the famed AKG CK-12 capsule.

It can be used as a direct swap for your AKG C12, and is a great choice for DIY C12 or ELA M 251 projects.

It’s also a recommended upgrade for inexpensive tube condenser microphones like the Apex 460, Alctron T-11A, and more.

Description

The RK-12 is a nice-sounding OEM AKG CK12 capsule replica manufactured in China. Compared to the original CK12 from AKG, it is a respectable performer with a slightly smoother high-frequency boost, and to a lesser effect, a slight low-frequency boost.

The RK-12 features 3-micron gold-sputtered mylar and supports both cardiod-only and multi-pattern microphone circuits.
