SM280708-2

Overview

The DB Unlimited SM280708-2 is a high-performance enclosed speaker designed for robust audio output in compact applications. It features an 8-ohm impedance and a nominal power rating of 1W. The device delivers a sound pressure level of 106 dBA with a frequency range spanning from 850Hz to 20,000Hz. Its physical dimensions include a height of 13.4 mm, supporting flush-mount or panel-mount installation styles.

Feature Summary

Enclosed acoustic design for enhanced performance
Flush-mount and panel-mount installation compatibility
Resistance to dust and splash exposure

Applications

Industrial equipment audio indicators
Consumer electronics requiring durable speakers
Automotive interior communication systems

Procurement Notes

Verify the specific datasheet version for exact mechanical tolerances and environmental ratings before integration. Confirm that the 8-ohm impedance matches the driving circuit requirements. Ensure the mounting style aligns with the enclosure design constraints.

Selection Notes

Select this component when a sealed enclosure is required to maximize sound pressure level within a limited volume. Consider the 13.4 mm height constraint against available space. Evaluate the 1W power handling against the intended signal amplitude to prevent distortion.

Part Context

This model belongs to the Agile series of audio solutions from DB Unlimited. It is categorized as a high-performance enclosed speaker, distinct from open-back dynamic speakers or waterproof transducers. The series focuses on delivering high SPL in small form factors.

Replacement Considerations

Check the SM280708-1 for similar specifications, noting potential differences in port configuration or decibel levels. Verify impedance and power ratings match exactly to ensure circuit compatibility without redesign.
