CLS0571M-L152

Overview

The CLS0571M-L152 is a low-profile, round speaker manufactured by Same Sky. It features an 8-ohm nominal impedance and a rated power of 200 mW, with a maximum power handling of 400 mW. The device delivers a sound pressure level of 89 dBA at 1W/10cm. Its frequency response spans from 530 Hz to 20 kHz, with a self-resonant frequency of 530 Hz. The unit has a diameter of 57 mm (2.244 inches) and a maximum height of 6.0 mm (0.236 inches). It utilizes a PET diaphragm and Nd-Fe-B magnet, terminating via wire leads.

Feature Summary

• Low-profile design suitable for space-constrained enclosures
• High sensitivity output for efficient audio reproduction
• Wide frequency range extending into high frequencies
• Robust magnetic structure using neodymium iron boron

Applications

• Portable consumer electronics
• Medical devices requiring compact audio output
• Industrial control panels
• Smart home appliances

Procurement Notes

Verify the specific suffix L152 to confirm wire lead termination type. Ensure the enclosure design accommodates the 57 mm diameter and 6.0 mm height constraints. Confirm that the 200 mW rated power aligns with the target application's audio drive levels to prevent distortion or damage. Check RoHS compliance status if required by regional regulations.

Selection Notes

Select this model when a balance between wide frequency response and ultra-low profile is required. The 8-ohm impedance matches standard amplifier outputs. Consider the 89 dBA efficiency for battery-powered applications where power conservation is critical. Compare against larger diameter speakers if higher volume is needed, or smaller units if space is more restrictive than acoustic performance.

Part Context

This component belongs to the CLS series of miniature speakers from Same Sky. The series offers various diameters and power ratings. The CLS0571M variant specifically targets applications needing a 57 mm footprint. It shares design principles with other models in the lineup, such as consistent mounting hole patterns and similar terminal configurations across the family.

Replacement Considerations

Direct substitutes include CLS0571MA-L152 for identical specifications with potential minor manufacturing variations. Other Same Sky models like CLS0571M-L151 may differ only in packaging or lead length. Verify impedance and dimensions before swapping with non-Same Sky brands.
