Large-diaphragm replacement capsules

The company offers several large-diaphragm replacement/upgrade capsules, modeled carefully after the European originals:

  1. RK-47 - a 34mm, dual-diaphragm, single-backplate capsule that recreates the sound of the Neumann K47 capsule.
  2. RK-12 - a 34mm, dual-diaphragm, edge-terminated capsule based on the AKG CK-12. This capsule has received glowing reviews for vocal applications, and provides an affordable upgrade for C12-like tube mic mods (e.g. the Apex 460).
  3. RK-87 - a version of the Neumann K67/K87, made with 3-micron diaphragms and insulated backplates. It works in both 3-wire and 4-wire microphone designs.
