SP-1813-2

Overview

The SP-1813-2 is a general-purpose dynamic speaker manufactured by Soberton Inc. It features an oval form factor with a top port location and wire leads for connection. The unit has an impedance of 8 Ohms and a power handling capacity of 800 mW. Its frequency response ranges from 300 Hz to 4 kHz, and it achieves a sound pressure level of 90 dBA. The component is RoHS compliant.

Feature Summary

• Oval dynamic driver design with top port configuration
• Wire lead termination for direct circuit integration
• RoHS compliant construction

Applications

• Ultrasonic neuromodulation research systems
• General purpose audio output devices
• Mobile device speaker units

Procurement Notes

Verify the specific datasheet version when ordering, as some sources list 500 mW and 86 dB while others specify 800 mW and 90 dB. Confirm that wire leads are required rather than surface mount options. Ensure the oval shape fits the mechanical constraints of the target enclosure. Check RoHS compliance status if operating in regulated regions.

Selection Notes

Select this model for applications requiring a compact oval speaker with wire leads. The 8 Ohm impedance suits standard low-voltage drivers. The 300 Hz to 4 kHz range limits bass reproduction, making it suitable for mid-range or ultrasonic generation rather than full-range audio. Verify the 800 mW rating against thermal management capabilities in enclosed spaces.

Part Context

This part belongs to the Soberton SP-1813 series of dynamic speakers. The series includes variants such as the SP-1304 and SP-1813S. These components are designed for mobile and general-purpose applications. The SP-1813-2 specifically denotes the 8 Ohm variant with wire leads.

Replacement Considerations

The SP-1304 is a documented alternative within the same product line, though it differs in impedance (32 Ohms) and power rating (200 mW). Direct substitution requires verifying electrical compatibility with the driving circuit.
