This subwoofer system is ready to install in your boat and features rock-solid, all-fiberglass enclosure construction with a beautiful, matte-white gel-coat finish.

The sealed enclosure is precisely tuned to deliver outstanding quality sub-bass response in an open-air boat installation. Loaded inside, is our maximum-performance M6-10W 10" Subwoofer.

This system is best used with amplifier power in the 75 - 250W range. The enclosure is not drilled for speaker cable. This allows the installer to select the best surface to exit the cable from, based on the specific installation.

Like all JL Audio marine speakers, this system is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.

Production of all M6 loudspeakers takes place in JL Audio’s Miramar, Florida factory, using global components and materials.

Marine Materials / Testing

The design of marine products requires extensive materials testing to achieve reliability and longevity.

Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.

Materials Used

  • Injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
  • Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
  • Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
  • Gold-plated, marine-grade brass connection terminals
  • Marine-grade stainless steel mounting hardware is included.

DMA Optimized Motor

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

Built-In USA with Global Components

At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.
