FED SERIES
– Balanced Armature Speaker 6.32 x 4.31 x 2.47 (mm)
The addition of Ferrofluid
to Knowles ED series speakers improves mechanical shock
survival and provides peak damping to smooth frequency response.
Ferrofluid
damped with 2dB, 4dB, or 6dB peak amplitude
Superior shock performance and reduced speaker vibration
Two-terminal zero-bias and three-terminal center-tapped configurations
Numerous port locations and coil impedances
Sensitivity @ 1kHz
