Speakers Procurement Notes

Verify the specific suffix P101 against official Knowles documentation to confirm side-port orientation and acoustic tuning. Ensure the procurement channel provides valid traceability for this component. Confirm RoHS compliance status through current manufacturer declarations prior to finalizing acquisition.

Speakers Selection Notes

Select this component when space constraints require a low-profile balanced armature receiver. The 128 Ohm impedance matches specific driver requirements. Evaluate the 102.5 dBA sensitivity against system gain needs. Consider the side-port layout for enclosure design integration.

Speakers Part Context

This part belongs to the ED/FED series of balanced armature receivers from Knowles. The series utilizes proprietary balanced armature technology originally developed by the manufacturer. These components are engineered for high reliability in miniaturized audio applications.

Speakers Replacement Considerations

Consult official Knowles substitution guides for verified equivalents. Generic replacements may not match the specific 128 Ohm impedance or 102.5 dBA sensitivity profile required for proper system integration.
