Procurement Notes

Verify the specific ordering suffix against official RDI documentation to confirm exact mechanical dimensions and electrical tolerances. Ensure compatibility with existing mounting holes and wiring harnesses. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with current manufacturer lists to verify active production status before finalizing procurement orders.

Selection Notes

Select this component when a compact, low-power speaker is needed for general audio applications. The 8-ohm impedance suits standard amplifier outputs. Consider the 500 Hz to 4.5 kHz frequency response for voice or simple tone generation rather than high-fidelity music. The 1.575-inch diameter fits tight spaces where larger drivers cannot be installed.
