Speakers Procurement Notes

Verify the exact part number CMS-2811-44E against official Same Sky documentation to confirm specifications. Ensure compatibility with existing circuit designs regarding impedance and power handling. Check for any recent updates to the datasheet that may affect mechanical dimensions or electrical parameters before finalizing procurement.

Speakers Selection Notes

Select this component when a compact 28 mm round speaker is required. Consider the 4 ohm impedance and 3 W power rating for amplifier matching. The 300 Hz low-frequency limit defines its suitability for voice or alert tones rather than full-range music reproduction. Verify mounting hole patterns match the 28 mm diameter specification.

Speakers Part Context

This model belongs to the Same Sky miniature speaker series, specifically designed for small form factor applications. It represents a standard offering in their lineup of general-purpose transducers. The product line emphasizes compactness while maintaining reliable acoustic output for basic audio signaling needs.

Speakers Replacement Considerations

Direct substitutes must match the 28 mm diameter, 11 mm depth, 4 ohm impedance, and 3 W power rating. Verify that alternative models support solder eyelet termination and similar frequency response characteristics to ensure functional equivalence in the target application.
