M2D4/D2-10IB

The Rockford Fosgate M2D4-10IB and M2D2-10IB are high-quality 25 cm (10-inch) marine subwoofers from the M2 Series, designed specifically for powerful bass reproduction under demanding conditions. Thanks to their Element Ready™ construction with IP67 certification, these subwoofers are ideal for boats and other marine applications.

The subwoofers are optimized for infinite-baffle or free-air installations and do not require a sealed enclosure. A stable mounting surface with acoustic isolation between the front and back is required.

The built-in Color Optix™ RGB LED lighting allows for custom color configurations and can be controlled using an optional Rockford Fosgate Color Optix™ controller and the RF Connect™ app.

With VersaSwitch™ technology, the total impedance can be easily adjusted using an integrated switch, without having to manually rewire the voice coils. The rugged polypropylene diaphragm, UV-resistant materials, and corrosion-protected terminals ensure high durability and long-lasting performance.
