Overview
The SP-2027 is a general-purpose rectangular speaker manufactured by Soberton Inc. It features an 8-ohm impedance and a power rating of 1W. The frequency response range spans from 700Hz to 10kHz, with a self-resonant frequency of 700Hz. The device has a sensitivity of 83dB and utilizes top porting for sound output. Physical dimensions are 27mm x 20mm x 6.4mm, designed for solder mount installation.
Feature Summary
- Rectangular form factor with top porting design
- Solder eyelet post mounting style
- General purpose audio reproduction
Applications
- Embedded audio systems
- Consumer electronics enclosures
- Industrial control panels
Procurement Notes
Verify the specific impedance requirement (8 Ohms) against circuit design specifications before procurement. Confirm that the 1W power rating aligns with the amplifier output capabilities. Ensure physical clearance accommodates the 27x20x6.4mm dimensions and solder eyelet post mounting method. Check datasheet revisions for any updates to acoustic parameters or material composition.
Selection Notes
Select this component when an 8-ohm load is required rather than the 4-ohm variant (SP-2027NW). Consider the 700Hz lower frequency limit suitable for voice or alert tones rather than full-range music. The rectangular shape aids in fitting tight PCB layouts compared to circular speakers. Verify sensitivity requirements match the available drive voltage.
Part Context
This part belongs to the SP Series of micro speakers from Soberton Inc., which includes various impedance and size options. It is distinct from the SP-2027NW model, which offers 4-ohm impedance and a slightly different frequency response starting at 750Hz. Both share similar physical footprints but differ electrically.
Replacement Considerations
The SP-2027NW serves as a direct alternative if 4-ohm impedance is acceptable. Other Soberton SP series speakers may fit mechanically but require electrical verification. Cross-referencing datasheets is essential to ensure compatibility with existing amplifier stages.
