Speakers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact configuration details. Ensure compatibility with target enclosure acoustics regarding the top port design. Confirm that the 700 mW power rating aligns with the driving circuit capabilities to prevent thermal damage during operation.

Speakers Selection Notes

Select this component when a low-profile rectangular speaker is required for space-constrained designs. The 8 Ohm impedance suits standard audio driver outputs. Consider the 93 dBA sensitivity for applications requiring moderate volume without excessive amplification. Verify that the 500 Hz to 10 kHz frequency response meets the specific audio fidelity requirements of the end product.

Speakers Part Context

This model belongs to the CMS series of micro speakers from Same Sky, formerly CUI Devices. The series offers various shapes and sizes tailored for embedded audio applications. This specific part represents a standard rectangular variant within the lineup, balancing size constraints with adequate acoustic performance for general-purpose signaling and voice reproduction tasks.

Speakers Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements may differ in impedance, SPL, or physical mounting dimensions. Ensure any substitute maintains the 8 Ohm impedance and compatible power handling to preserve circuit integrity.
