CES-271911-158PM

Overview

The CES-271911-158PM is a rectangular, general-purpose speaker with an integrated enclosure manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 1.5 W, with a maximum power handling of 1.7 W. The frequency range spans from 600 Hz to 5 kHz, with a self-resonant frequency at 750 Hz. The unit delivers a sound pressure level of 95 dBA when tested at 1.5 W/100mm. Physical dimensions are 27.10 mm in length, 19.20 mm in width, and a maximum installation height of 12.95 mm. It utilizes a foam cone and Nd-Fe-B magnet, terminating via wire leads with a connector.

Feature Summary

• Integrates a magnetic circuit with a neodymium iron boron magnet and a foam diaphragm for acoustic output.
• Enclosed design provides a ready-to-install solution with top-mounted porting.
• Terminates using wire leads equipped with a connector for simplified assembly.

Applications

• Audio and video equipment
• General purpose audio signaling

Procurement Notes

Verify the specific suffix against official documentation to confirm exact configuration details. Ensure the operating temperature range of -20°C to 60°C aligns with the target environment. Confirm that the 1.5 W rated power and 8 Ohm impedance match the system requirements. Check for RoHS compliance status if required by the application standards.

Selection Notes

Select this component for applications requiring a compact, enclosed speaker with a broad mid-range frequency response. The 1.5 W power rating suits low-power audio tasks. Verify that the physical footprint of 27.10 mm by 19.20 mm fits within the available chassis space. Consider the top-port orientation for acoustic placement constraints.
