TEC Balanced Armature Speakers

Knowles TEC Balanced Armature Speakers are intended for use in high power hearing aids and combine output comparable to the larger BK receiver in an ultra-thin package. They are a similar size to an EF receiver and have a medium DCR to impedance ratio. The operating sensitivity does not vary more than +1/-3dB from -17°C to +63°C. DTEC Balanced Armature Speakers (7.87mm x 4.09mm x 5.59mm) combine two TEC speakers with a single round port. Case size is equivalent to BK/EF. DTEC provides increased output and reduced vibration compared to a single speaker.
