Speakers Procurement Notes

Verify the specific datasheet version when sourcing, as manufacturer documentation may vary by region or revision date. Confirm that the 115 Ohm impedance matches the target circuit requirements. Ensure the side-port orientation aligns with the acoustic enclosure design to maintain specified sensitivity levels during integration.

Speakers Selection Notes

Select this component when a compact, high-sensitivity receiver is required for space-constrained designs. The 115 dB sensitivity ensures adequate volume output from low drive voltages. Consider the rectangular shape and side port layout for optimal placement within tight chassis boundaries compared to standard top-port alternatives.
