SP-1813

Overview

The SP-1813 is a dynamic electromagnetic speaker manufactured by Soberton Inc. It features an oval form factor with top port location and wire leads for connection. The component operates at an impedance of 8 Ohms and has a rated power handling capacity of 500 mW. Its frequency response range spans from 300 Hz to 8 kHz, with a self-resonant frequency of approximately 800 Hz. The unit delivers a sound pressure level of 88 dB.

Feature Summary

• Top port acoustic design for directional sound projection
• Oval physical geometry suitable for compact enclosures
• Wire lead termination for direct circuit integration

Applications

• General purpose audio output devices
• Compact consumer electronics enclosures
• Industrial signaling or alert systems

Procurement Notes

Verify the specific suffix variant (e.g., SP-1813 vs SP-1813-2) as sensitivity and power ratings may differ between versions. Confirm RoHS compliance status and lead material specifications against current manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this model when a low-profile oval speaker with top-port acoustics is required. Ensure the application environment supports the 8 Ohm impedance load and that the 500 mW power rating aligns with the amplifier output capabilities to prevent thermal damage.

Part Context

This component belongs to the Soberton general-purpose speaker series. It utilizes a dynamic electromagnetic transducer mechanism. The product line typically includes various sizes and mounting configurations, with this specific part optimized for space-constrained applications requiring moderate acoustic output.

Replacement Considerations

The SP-1813-2 is a documented variant within the same family. Verify if the higher sensitivity (90 dBA) and increased power rating (800 mW) of the -2 variant are acceptable substitutes for the standard SP-1813 specifications.
