Procurement Notes
Verify the specific datasheet version for the AS04204PR-2 to confirm exact dimensional tolerances and electrical parameters before finalizing the design. Ensure the selected application environment matches the component's operational limits. Cross-reference the manufacturer's official documentation for any updates regarding material specifications or compliance standards relevant to your region.
Selection Notes
Select this component when a 4-ohm impedance and 10W power rating align with the system requirements. The 90 Hz to 20 kHz frequency range supports broad audio reproduction needs. Consider the 42mm diameter and 0.97-inch height for enclosure fitment. Verify that the 83.5 dBA efficiency meets the required sound pressure levels for the intended use case without excessive amplification.
