TSB-2555B Capsule With Mount

The Transound TSB-2555B is one of the most popular electret microphone capsules in the DIY Audio community. It is a medium-diaphragm (21mm) design praised for its high output, clean sound and smooth frequency response. We bundle the capsule with our proprietary mounting post, which we modeled on the mounting post of the Neumann U87 Ai. This post enables the TSB capsule to be easily installed in common inexpensive FET condenser bodies, including the BM-700 / BM-800, Apex 435, and CAD GXL2400. This mounting post raises the capsule as far as possible above the deck, to minimize the effect of reflected audio waves, while still fitting inside the mesh headgrille of the microphone. Included with the capsule are two pieces of multistrand silver/Teflon hookup wire, and the screws needed to install the mount in the donor microphone.
