SUFR7010

Overview

The SUFR7010 is a 2.75-inch full-range speaker unit featuring a ferrite magnet structure and a nominal impedance of 4 ohms with a power rating of 10 watts. It exhibits a resonant frequency of 100Hz and operates within a frequency range of 100Hz to 20kHz. The driver utilizes a round cone design housed in a square frame, providing a compact audio solution suitable for various electronic projects.

Feature Summary

• Ferrite magnet construction for reliable magnetic performance
• Full-range capability covering mid to high frequencies
• Compact physical dimensions optimized for space-constrained enclosures

Applications

• DIY audio amplifier projects
• Small enclosure speaker replacements
• Educational electronics kits

Procurement Notes

Verify the specific impedance variant upon ordering, as sources indicate both 4-ohm and 4.27-ohm configurations exist under similar identifiers. Confirm the manufacturer origin, noting distribution by Sure Electronics and potential listing under Multicomp Pro branding. Ensure the square frame geometry matches your existing mounting requirements before purchase.

Selection Notes

Select this component when a small form factor is required alongside moderate power handling capabilities. The ferrite magnet offers a cost-effective alternative to neodymium drivers while maintaining sufficient output for near-field listening. Consider the 100Hz resonance limit when designing passive radiators or bass reflex ports, as low-frequency extension is limited by the driver's natural characteristics.

Part Context

This model belongs to the Sure Electronics lineup of professional industrial audio solutions. It is frequently associated with Wondom Audio Technology designs. The unit serves as a middleware component for hobbyists seeking reliable transducers for custom amplifier builds, bridging the gap between generic components and specialized high-fidelity drivers.

Replacement Considerations

Direct substitutes include the AA-SP15116 and MP-SUFR7010 variants. Verify dimensional compatibility, particularly the square frame mounting holes, when replacing units from different manufacturers. Impedance matching remains critical to ensure proper amplifier loading.
