Procurement Notes

Verify the specific datasheet version when sourcing to ensure compatibility with wire length and enclosure specifications. Confirm that the 4-ohm impedance matches the driving circuit requirements. Check for availability as stock levels may fluctuate due to the component's status as a general-purpose part. Ensure the plain wire termination suits the intended connection method without requiring additional adapters.

Selection Notes

Select this component when a compact, low-cost audio solution is needed for simple circuits. The 4-ohm impedance requires appropriate amplification or driver stages to operate efficiently at the rated 3-watt capacity. Consider the physical dimensions of the top oval frame to ensure it fits within the project enclosure constraints. Verify that the plain wire ends are suitable for the soldering or connection technique used in the assembly process.
