M6 8-inch Marine Subwoofer for Infinite-Baffle Use (200 W, 4 ) - White Trim Ring, White Luxe Grille

With appropriate system setup, the addition of a subwoofer frees your smaller main speakers from the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.

M6 Luxe subwoofers are outfitted with a low-profile mounting bezel and a fine mesh grille for minimal protrusion into cabin space. The result is a clean, visual appearance complementary of the finest marine vessel surroundings.

Engineered to operate without a dedicated enclosure, M6 infinite-baffle woofers feature a DMA-optimized, long excursion design and rugged suspension systems to generate smooth, powerful bass that will transform your boat s audio system.

The M6-8IB is best used with amplifier power in the 50W - 200W range and is optimized to operate with a large volume of air behind it (at least 1.5 cu. ft. / 42.5 l). If you prefer to use a dedicated enclosure, refer to one of the suggested designs located in the Specifications section for optimum performance.

Like all JL Audio marine speakers, this driver 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.

Sold individually.


Dynamic Motor Analysis - 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.

Marine Materials / Testing

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

Built in U.S.A. with Global Components

JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
