Speakers Procurement Notes

Verify the exact sensitivity specification against the manufacturer's current datasheet, as distributor listings may vary between 114 dB and 117 dB ratings for similar rectangular models. Confirm RoHS3 compliance status directly with the supplier to ensure adherence to latest environmental regulations. Request official documentation to validate the side port orientation and mechanical dimensions prior to integration into custom PCB layouts or enclosure designs.

Speakers Selection Notes

Select this component when a rectangular electromagnetic speaker with high sensitivity is required for direct sound projection. The side port design influences acoustic coupling and should be matched with enclosure geometry to optimize frequency response. Ensure the driving circuit can handle the impedance characteristics typical of electromagnetic speakers in this class. Verify mechanical mounting requirements align with the target application's structural constraints.

Speakers Part Context

This part belongs to Knowles' electromagnetic speaker portfolio, which includes various rectangular and circular configurations. The EF series typically denotes specific porting and sensitivity variations within the standard rectangular speaker lineup. These components are engineered for reliability in commercial and industrial audio applications where consistent performance and compact form factors are prioritized over high-fidelity reproduction.

Speakers Replacement Considerations

Direct substitutes include other Knowles rectangular electromagnetic speakers with comparable sensitivity and porting, such as those in the EF series with matching 114 dB or 117 dB ratings. Cross-reference mechanical dimensions and terminal configurations to ensure compatibility. Alternative manufacturers offering rectangular electromagnetic speakers with similar acoustic output and RoHS compliance may serve as secondary options if supply chain constraints exist.
