The Telefunken Elektroakustik ELA M 251T Tube Microphone features the CK-13 capsule. While based upon the classic ELA M 251 models, the ELA M 251T adds a very modern twist.
That twist is the implementation of Alloy 2213 as the diaphragm membrane material for the CK13 capsule and a NOS Siemens ECC801S vacuum tube. Alloy 2213 is an amalgam of Titanium and Aluminum, which was originally developed for the aerospace industry. Traditionally gold has been sputtered onto Mylar for the diaphragms of the historic CK-12 capsule. By employing Alloy 2213, which is far more rigid than gold, Telefunken Elektroakustik has developed a capsule that provides greater accuracy in the low frequency ranges of the audio spectrum by attaining a higher damping factor to the motion of the membrane. Alloy 2213 is lighter than gold, and when combined with the edge terminated CK-12 system provides an "airy" and "delicate" representation of the upper ranges of the audio spectrum. This affords the user a higher degree of detail in the recorded sound while still providing the depth of audio for which ELA M 251 microphones have been associated for decades. After extensive R&D, the perfect diaphragm tuning and fabrication was achieved, resulting in a microphone capsule that can better withstand moisture, smoke, and extreme volume, thus requiring less maintenance over the years, and provides the user a superior capture of the sound to be recorded.
