TELEFUNKEN Elektroakustik introduces the new ELA M 251T, a microphone featuring the newly developed 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 CK-13™ capsule. Alloy 2213™ is an amalgam of Titanium and Aluminum, which was originally developed for the aerospace industry.
