Sound Pure's Take
When Austrian Audio emerged from the legacy of AKG's former Vienna team, they set out to modernize one of the most legendary sound signatures in recording history. The Austrian Audio OC18 is the purest realization of that vision. It takes the hand-built, edge-terminated capsule architecture of the iconic C12/C414 family and reimagines it with cutting-edge materials and a single-diaphragm, fixed-cardioid design.
At the heart of the OC18 is the handmade CKR12 ceramic capsule. By replacing traditional brass capsule housings with precision-molded ceramic, Austrian Audio achieved unmatched physical consistency. The result? Any single OC18 off the production line is factory-matched to within 1dB of any other OC18 or OC818. Sonically, it delivers that coveted Viennese character: open, detailed top-end air and articulate midrange without the harsh, hypes-up sibilance that plagues many modern condensers.
From Austrian Audio
Consistent performance
Engineered and manufactured in Austria, its high sensitivity and low self-noise means it can handle everything from a whisper, to extreme SPLs without distortion, making it the perfect choice for studio, live and broadcast applications. The unique ceramic capsule design is so consistent, the OC18 can be match-paired with any other OC18 or paired with any OC818 set in cardioid mode.
