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.
GQ SERIES
The GQ is a two-way balanced armature system with added low frequency
headroom, designed for pro-audio\in-ear application. Enables customized
cross-over response to achieve target frequency response.
Note: All performance curves are typical
