Speaker grille BLOW 5142# for 30 cm (12") speakers — protective metal cover

Protective speaker grille BLOW 5142# is designed for 30 cm (12") speakers and functions as a durable metal front cover that shields the speaker cone and internal components while allowing sound to pass through. The grille fits into speaker enclosures where a 30 cm diameter opening is required and can be used as a replacement part or as an upgrade for car audio, public address systems and home speaker cabinets. Its metal construction provides impact resistance and helps prevent dust and foreign objects from reaching the driver.

Advantages

The metal grille offers robust mechanical protection without significantly affecting acoustic output. Its perforated design maintains sound transmission and minimizes resonance while providing a hard barrier against accidental contact and debris. The grille is easy to install in standard mounting arrangements for 30 cm speakers and is corrosion-resistant when used in typical indoor and automotive environments.

Suitable for

• Replacement of front protection on 30 cm (12") speaker enclosures
• Car audio systems requiring a metal protective cover for mid-bass or subwoofer drivers
• PA and DJ speaker cabinets exposed to transport and physical impact
• Home speaker cabinets where dust and pet protection is needed

Key specifications

• Compatible speaker diameter: 30 cm (12")
• Material: protective metal grille (perforated)

How to use

Measure the speaker opening to confirm compatibility with a 30 cm (12") grille. Remove the existing grille or any fabric cover, align the metal grille with the enclosure's mounting holes, and secure it using appropriate fasteners or clips provided by the enclosure manufacturer. Ensure the grille is centered and does not contact the speaker cone or surround to avoid rattling. For installations in vehicles, check that the grille does not interfere with trim or door panels.

Usage recommendations

Regularly inspect the grille for dents or loose fasteners after transport or heavy use. Clean the metal surface with a soft cloth and mild detergent if needed; avoid abrasive tools that could damage the finish. When used in outdoor or high-humidity environments, verify the grille's corrosion resistance and consider additional protective coatings if required.
