SPM-4343W

Overview

The SPM-4343W is a general-purpose round speaker manufactured by Soberton Inc. It features an 8-ohm impedance and handles an input power of 2.0/2.5 watts. The device delivers a sound pressure level of 100 dB with a frequency response range of 1200 Hz to 20 kHz. Its physical dimensions are 43.5 mm in diameter and 13.05 mm in height, utilizing a top port configuration.

Feature Summary

• Round shape design for versatile mounting
• High efficiency sound output at 100 dB
• Top port acoustic configuration

Applications

• General purpose audio amplification circuits
• IoT project audio components
• Maker electronics prototypes

Procurement Notes

Verify the specific datasheet version from Soberton Inc. or authorized distributors to confirm exact tolerances for impedance (+/- 15%) and frequency response (+/- 3dB). Ensure compatibility with existing enclosure designs regarding the 43.5mm diameter and 13.05mm height constraints before finalizing procurement.

Selection Notes

Select this component when a high-efficiency (100 dB) round speaker is required for low-to-mid frequency applications starting at 1200 Hz. The 8-ohm impedance suits standard amplifier outputs, while the 2.0/2.5W power rating supports moderate volume requirements in compact enclosures.

Part Context

This model belongs to the WSPH series from Soberton Inc., which focuses on standard test condition speakers. It is distinct from rectangular models like the SP-2809, offering a circular form factor suitable for different aesthetic or spatial integration needs in consumer electronics.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternatives based on matching 8-ohm impedance, 100 dB SPL, and 43.5mm diameter dimensions.
