SPECIALTY TRANSDUCERS – Speakers
SR SERIES
At 8.8mm diameter, the SR is the first round balanced armature speaker in the
marketplace. SR offers output equivalent to the BK series and maximizes
bass performance.
CI SERIES
Knowles’ largest and most powerful speaker, the CI series is the speaker of choice.
With its high efficiency and a 143dB SPL maximum output, the CI speaker provides
optimal low frequency performance.
Note: All performance curves are typical
