SPECIALTY TRANSDUCERS – Speakers
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.
SR SERIES
At 6.4mm diameter, the Mini SR is the smallest round balanced armature speaker in
the marketplace. SR offers output equivalent to the FC series and maximizes
bass performance.
EC SERIES
EC Series speakers are commonly used in isolating earphones for radio communication.
