The JBL MTC-28WMG-1-WH is a specialized WeatherMax replacement grille cover designed for the JBL Control 28-1 all-weather loudspeaker. This component is engineered as a durable, direct-replacement accessory to restore or update the protective front face of the speaker enclosure in outdoor or harsh indoor environments. Constructed from UV-stabilized, high-impact polymer, the grille is built to withstand prolonged exposure to sunlight, moisture, temperature extremes, and physical impact without degrading, ensuring the internal transducer components remain protected while maintaining optimal acoustic performance. Its primary function is to provide long-term defense against the elements while allowing sound to pass through with minimal obstruction or coloration.

The grille features a robust, open design with precise perforation patterns that are acoustically transparent, ensuring high-frequency detail and overall sonic integrity are not compromised. The white finish is formulated to resist fading and yellowing over time, helping the speaker maintain a clean, professional appearance in architectural settings. As a genuine JBL accessory, it is manufactured to exact specifications, guaranteeing a perfect fit that aligns with the original mounting points and seals correctly with the speaker's gasket, maintaining the unit's weatherproof integrity. This is critical for preserving the IP rating and overall durability of the Control 28-1 loudspeaker in permanent installations.

Installation is a straightforward process, typically involving the removal of a few screws from the old grille and securing the new one in its place, making it a practical solution for maintenance crews or installers. This replacement part extends the service life and aesthetic appeal of the loudspeaker system, offering a cost-effective alternative to replacing an entire speaker unit when only the grille has sustained damage or wear. It exemplifies the support for long-term system upkeep, ensuring that professional audio installations can maintain both their performance and their appearance for years with genuine, purpose-built components.
