SP-1609

Overview

The SP-1609 is a general-purpose dynamic speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a rectangular shape with top port location. The unit operates within a frequency range of 200 Hz to 3.4 kHz, with a self-resonant frequency of approximately 650 Hz. It has a sound pressure level of 82 dB and handles a maximum input power of 500 mW. Termination is provided via wire leads.

Feature Summary

• Rectangular form factor with top port configuration
• Wire lead termination for direct connection
• General-purpose dynamic driver design

Applications

• Consumer electronics audio output
• Industrial control panel indicators
• Embedded system alert systems

Procurement Notes

Verify the specific datasheet version for the SP-1609 to confirm exact dimensional tolerances and thermal limits. Ensure the application environment does not exceed the 500 mW power rating. Confirm wire lead length requirements prior to integration into the final assembly design.

Selection Notes

Select this component when a low-cost, general-purpose rectangular speaker is required. The 8-ohm impedance matches standard amplifier outputs. Consider the SP-1609-2 variant if higher sensitivity (92 dB) and wider bandwidth are needed, as it shares similar physical dimensions but offers different acoustic performance characteristics.

Part Context

This part belongs to the SP Series of dynamic speakers from Soberton Inc. The series includes various models like SP-1605 and SP-1606, offering different power ratings and frequency responses while maintaining consistent mounting styles. The SP-1609 represents the mid-range option in terms of power handling within this specific rectangular form factor family.

Replacement Considerations

The SP-1609-2 is a related model with higher sensitivity (92 dB vs 82 dB) and broader frequency response (300 Hz ~ 5 kHz). It may serve as a functional substitute if increased volume or extended high-frequency response is acceptable, though the impedance remains identical at 8 ohms.
