Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm current technical specifications. Ensure compatibility with existing amplifier output impedance and power handling capabilities. Confirm mechanical mounting requirements align with the 76 mm diameter and 34.5 mm depth constraints before finalizing procurement.

Selection Notes

Select this component when a compact, high-output solution is required for mid-range frequencies. The 4-ohm impedance suits standard low-impedance amplifier outputs. Consider the 88 dB(A) sensitivity for applications requiring high volume without excessive power consumption. Verify that the 400-5000 Hz bandwidth meets the specific audio transmission needs.
