SPECIALTY TRANSDUCERS – Speakers
EH SERIES
EH Series speakers are approximately 2/3 the size of ED speakers and may be used for small
radio communication earphones where ED size does not meet package requirements.
ES SERIES
EH size speaker with integrated Class D power amplifier
EP SERIES
Based on Knowles’ versatile and popular ED speaker, the EP series adds the benefits of
an internal Class-D amplifier. Its compact size and appreciable output power make the EP
speaker suitable for a variety of designs.
Note: All performance curves are typical
