2PCS Knowles HODVTEC-31618 BA Balanced Armature Receiver Dual Bass Driver

Knowles TEC Series 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 similar in size to an EF receiver and have a medium DCR-to-impedance ratio. The TEC Series operating sensitivity will not vary more than +1/-3dB from -17ºC to 63ºC.

DTEC Series Balanced Armature Speakers (7.87 x 4.09 x 5.59mm) combine two TEC speakers with a single round port. The housing size is equivalent to BK/EF. DTEC provides increased output and reduced vibration compared to a single speaker.

Reminder:

Please test the driver first before soldering, replacements are not available once drivers are soldered
