Built for life on the water

Built from the ground up for the marine environment, the M10W5-CG-WH sports a corrosion-resistant Centrex® polymer basket that surrounds the sub's internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide top performance, while shrugging off the corrosive effects of sun, salt, and moisture.

The UV-resistant polymer basket encases and protects the entire structure, and as an added bonus the UV protection ensures the grilles will stay white, looking factory-fresh even after years of sun exposure.

Designed for sealed or ported enclosures

The subwoofer's motor structure allows extended cone movement, so you'll hear bass that's loud and low, yet precise and smooth. JL Audio designed the M10W5-CG-WH for sealed or ported enclosures, so you can mount it in the type of box that matches your taste in music.

Product Research


Marine Tested: JL Audio's marine subwoofers go through ultraviolet testing chambers (to simulate years of sun exposure) and salt fog chambers (to simulate years of exposure to salt-water environments and are built to withstand the rigors of marine use.

Woofer: The JL Audio Marine 10" subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a synthetic rubber surround specifically formulated for marine duty. The woofer uses a vented motor design with a marine-grade stainless steel rear diffuser plate and a marine-grade synthetic fiber spider with a progressive roll design.

DMA (Dynamic Motor Analysis): JL Audio's proprietary Dynamic Motor Analysis (DMA) technology results in ultra-linear motor force over a long range of excursion and a wide range of power inputs to reduce distortion and improve sound quality.

Polymer Basket And Grille: The Centrex, UV-resistant polymer basket and grille are corrosion and UV-resistant which help protect the woofer and encapsulates the motor assembly to prevent corrosion.

Connections: The 10" marine woofer is equipped with gold-plated, marine-grade brass connection terminals.

Mounting Hardware: The woofer comes supplied with marine-grade, stainless-steel mounting screws and washers.

Box Type: The M10W5-CG-WH marine 10" woofer can be mounted in a 0.875 cubic foot sealed enclosure or a 1.25 cubic foot ported enclosure with a single 3" diameter x 13" long port. The box should be constructed out of 5/8" to 3/4" thick material.
