Fusion SG-X77B 7.7" Grill Cover f/ SG Series Speakers - Black

The Fusion SG-X77B 7.7" Grill Cover for SG Series Speakers in black delivers protective functionality with a discreet aesthetic for marine audio installations. Designed to shield Fusion Signature Series speaker elements while maintaining a low-profile appearance, this replacement grill integrates seamlessly into dark-toned cabin and entertainment spaces without drawing attention to the audio infrastructure.

Constructed from perforated metal, the grill cover protects speaker cones and internal components from saltwater spray, UV exposure, and physical contact—critical concerns in marine environments where corrosion and material degradation directly impact longevity. The 7.7-inch diameter is engineered specifically for Fusion's SG Series speaker housings, ensuring proper fit and acoustic alignment. Black powder-coat or anodized finish resists oxidation and maintains appearance across extended periods of offshore exposure, outperforming unpainted metal alternatives in high-moisture conditions.

This replacement cover is essential for operators and recreational boaters maintaining Fusion Signature Series audio systems on vessels, watercraft, and offshore platforms. Whether refurbishing aged speaker assemblies or upgrading existing installations, the SG-X77B addresses the specific acoustic and environmental demands of marine audio design. Compatibility is limited to designated SG Series speaker models—verify housing diameter and mounting interface before ordering to ensure fit.
