EC SERIES
EC Series speakers are commonly used in isolating earphones for radio communication.
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.
Note: All performance curves are typical
