TEC SERIES
The TEC combines output comparable to the larger BK speaker in an ultra-thin package.
The TEC is suitable for multi-element earphone designs.
DTEC SERIES
The DTEC Series combines two TEC speaker elements with a single round port.
Case size is equivalent to BK/EF. DTEC provides increased output and reduced
vibration compared to a single speaker.
