Hertz MG 250.3 10-Inch Grille for ML 2500.3 & MP 250 Subwoofers

The Hertz MG 250.3 is a 10-inch (250 mm) protective subwoofer grille designed by Hertz specifically for its Mille Legend ML 2500.3 and Mille Pro MP 250 D2.3 / MP 250 D4.3 subwoofers. The full-metal structure pairs a solid cast-aluminium outer ring with a black steel mesh screen carrying a diamond-cut Hertz logo, shielding the cone from cargo, boots, and paws without audibly restricting output. Because compatibility is by subwoofer model rather than vehicle, it fits any install running one of those Hertz subs.

The mounting screws sit completely hidden behind the ring for a clean, factory-finished look in a trunk, console, or custom enclosure, and the mesh stands off the cone far enough to preserve full excursion clearance on these specific drivers - the reason Hertz builds a dedicated grille per subwoofer family instead of a generic cover.

Sold as a single grille; order one per subwoofer. Includes M5 self-tapping hexagon-socket mounting screws and a bit driver.

Compatibility

The MG 250.3 fits the Hertz ML 2500.3 (Mille Legend 10-inch) and the Hertz MP 250 D2.3 and MP 250 D4.3 (Mille Pro 10-inch, dual 2-ohm and dual 4-ohm voice-coil versions). It is not a universal grille: Hertz does not list it for other 10-inch subwoofers, and the 8-inch Mille subs (ML 2000.3, MP 200 series) take the smaller Hertz MG 200.3 grille instead.

FAQ

Which subwoofers does the Hertz MG 250.3 grille fit?

The Hertz Mille Legend ML 2500.3 and the Hertz Mille Pro MP 250 D2.3 and MP 250 D4.3 - all 10-inch (250 mm) Hertz subwoofers. Hertz does not list it for any other drivers.

Is mounting hardware included?

Yes. The grille ships with M5 self-tapping hexagon-socket screws and a matching bit driver, and the fasteners are hidden once installed.

Is this sold as one grille or a pair?

One single grille per package - order one for each subwoofer you want to protect.

Will the grille reduce the subwoofer's output?

It is an open steel-mesh design engineered by Hertz for these drivers, sized to preserve cone excursion clearance while protecting the sub from impact.
