M7: Our flagship subwoofer is a reference standard for marine subwoofers. Optimized for higher-powered, infinite-baffle operation, the M7-12IB subwoofers are designed to provide intense bass output, while withstanding the harsh marine environment.

M6: Our M6 subwoofers are maximum-performance designs in 10-inch or 8-inch sizes. They are offered in versions for infinite-baffle or small enclosure operation.

M3: Highly affordable, yet still offering the full JL Audio bass experience for moderate power systems. Offered only in infinite-baffle version.

Light it up! Illuminated versions of our M7 and M6 subwoofers are available, featuring our patented Transflective RGB technology (U.S. Patent #10,462,546). M3 subwoofers are available with optional standard RGB lighting. 

Built in USA: While we source marine-grade materials and component parts from suppliers around the world, we build every JL Audio marine subwoofer in our Miramar, Florida factory. This allows our engineering team to monitor production, ensuring that your subwoofers are precisely assembled to the highest quality standards.

Why you need subwoofers: A running powerboat produces a huge amount of low frequency noise from the motor(s) and the wind. As the boat gathers speed, it becomes impossible for small full-range speakers to overcome the noise without running into distortion or risking damage. Properly adding a subwoofer to your system adds the necessary low frequency output to overcome that noise. It also makes your main speakers sound cleaner and louder by not forcing them to do extra work in the low-frequency department. Everything sounds cleaner and louder and the bass now packs a serious punch.

We know bass: JL Audio’s marine subwoofers deliver the kind of bass that has made JL Audio famous in the automotive and home theater sound arenas. This is bass that will impress you, not only with its sheer level, but even more with its smoothness, balance and precision.
