Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before finalizing designs. Confirm that the 32 Ohm impedance matches the amplifier output requirements. Ensure the operating temperature range aligns with the intended application environment. Check for any recent product change notices or obsolescence announcements directly from the manufacturer.

Selection Notes

Select this model when a higher impedance than standard 8 Ohm speakers is required for specific driver compatibility. Consider the limited low-frequency response below 680Hz when designing for full-range audio applications. The small physical dimensions make it suitable for tight spatial constraints where larger drivers cannot fit. Evaluate the 84dBA sensitivity against the required volume levels for the target use case.
