JL AUDIO marine loudspeakers are specifically designed and engineered for the marine environment ensuring the exceptional sound quality retains its clarity season after season. Using the highest quality materials and state-of-the-art design engineering ensures a JL AUDIO speaker exposed to the harsh marine environment will retain its performance and appearance far longer than other speakers.

Usually located in highly exposed locations onboard, effective audio speakers require exceptional resistance to saltwater spray, UV attack and even direct hose spray during wash down. Speakers from JL Audio are therefore constructed differently from other marine speakers. Having already developed some of the world’s most highly acclaimed audio systems for the automobile industry, the design engineers at JL Audio were set the task of creating an effective system for marine applications that would produce the highest quality sound reproduction and unrivalled protection from the environment.

The resulting JL Audio speaker is exceptional; the tweeter is built into the baffle which creates a barrier to protect the main section of the speaker from water ingress. The performance is equivalent to a high quality home hi fi, while longevity far exceeds that of any competitive system. JL Audio speakers provide the boat owner with an outstanding experience which will endure season after season.



The JL Audio team knows what is demanded of a speaker out on the water and through its experienced engineers and designers has created a speaker that sounds simply phenomenal. Knowing there will be severe high frequency cancellation due to the abundance of environmental noises such as wind, waves, engines or sails, JL Audio voice all of its marine speakers more aggressively than they do a car speaker. This allows the speaker to perform as if there were no noise obstacles to deal with, providing complete clarity and depth.


It is not just the output potential that is important when designing a speaker, the projection and dispersion paths can be equally important. As well as speakers designed for listening on board, JL Audio also manufactures sports boat speakers which can be enjoyed behind the boat when swimming, wake boarding or water skiing. They therefore need to be able to project far enough and wide enough for someone riding the wake to be able to hear and enjoy. When developing the M880 coaxial speakers the goal was to find a combination of distance and width without compromising the sound quality. The resultant speaker has been described as “in a class of its own”.


JL Audio does not test its products on a soundboard like many of its competitors; all speakers at the prototype stage are tested out on the water. Products go through stringent moisture, salt, fog, thermal and UV testing as well as humidity testing with a range of 10% to 98%. Each component is individually tested and then tested again in various pairings until the best combination of materials is selected to ensure longevity onboard without compromising sonic performance.

Thermal testing ensures plastic based materials and adhesives will not crack or weaken during sudden temperature changes, such as a speaker sitting in the hot sun then getting splashed with cold water.

UV testing means plastic parts don’t fade or weaken after prolonged sun exposure, while moisture testing checks the impact of salt water, or salt air, on corrosion as well as the overall reliability after getting wet.


Because you expect great performance and top quality when you choose JL Audio for your marine audio system, our speakers use marine grade materials to ensure outstanding longevity in real-world boating use. Most importantly, our fanatical approach to sound quality is in full effect, optimized for moderate power systems.

M3 speaker systems are available in a wide range of colour and grille style combinations. Select models are available with multi-colour cone illumination, so you can add some visual highlights to your boat to go along with the great audio performance.

M6 speakers are designed to deliver a powerful and smooth sound in open-air boat environments. The M6 speaker systems are available in a wide range of beautiful looks. Choose from classic or sport grille systems, white or titanium colour schemes, and speaker sizes.

M6-650X Coaxial Speakers

The M650-CCX is our maximum performance speaker for traditional marine 6.5-inch mounting locations, allowing you to easily upgrade standard speakers on a wide range of boats.

M6-770X Coaxial Speakers

For an extra sonic edge, consider our oversized, 7.7-inch diameter coaxial M6. It delivers more bass, higher output and better clarity at high volume levels than 6.5-inch speakers, thanks to 20% more sound radiating area and a larger tweeter.

M6-880X Coaxial Speakers

For those who believe that there is no such thing as “too much of a good thing,” our massive 8.8-inch coaxials deliver a giant performance leap, even surpassing the output and low-frequency capabilities of our very capable 7.7-inch models.

The addition of a subwoofer on board your boat will make your whole system sound complete, with greater depth of sound, clarity and bass. JL AUDIO’s maximum performance marine subwoofers deliver exceptional bass that will impress not only with its sheer level, but even more with its smoothness, balance and precision.

But it’s not just about the bass; a properly implemented subwoofer system relieves the main speakers from the stress of having to reproduce the lowest frequencies in your music. Free from this burden, they can play louder and cleaner, giving you far better overall audio performance.


The M3 Subwoofers are the affordable alternative for those who value great bass performance in their boat. Designed by the same team and built on the same U.S. production line as the more expensive M6 Subwoofer Drivers, they deliver outstanding sub-bass performance in moderate power applications.

The M3-10IB is designed for infinite-baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure.

JL Audio M6 marine subwoofer drivers benefit from the same technological base that has produced the world's finest home and automotive subwoofers. They have been designed with the aid of our most advanced modelling technologies and are built with fanatical attention to detail in our Miramar, Florida factory to withstand years of duty in a true marine environment.

To achieve the best low-frequency performance in real-world, open-air marine environments, you need a specialized subwoofer driver. This is why we offer the M6 subwoofers in two distinct versions: Infinite Baffle Subwoofers and Subwoofers for Enclosures. Infinite Baffle Subwoofers can be installed in a variety of locations, without the need for dedicated enclosure. The Subwoofers for Enclosures feature extremely long linear excursion capability for outstanding output and low-distortion performance. They are available as raw drivers or pre-loaded in a 100% fiberglass enclosures, precisely tuned to extract optimum performance.

Mounting template


Armed with Bluetooth® v4.0 and the aptX® codec for outstanding audio fidelity, MBT units can receive audio wirelessly from a compatible streaming device, located up to 11 metres away. A stereo pair of 2 volt RCA outputs connects to any amplifier or source unit with line-level/auxiliary inputs.

The very compact MBT-RX Bluetooth® Audio Receiver can be hidden out of sight in almost any installation location, allowing full control of the tunes from a mobile device wirelessly. It is an ideal solution for many types of vessels from sports powerboats to sailing yachts, where space is at a premium.

The MBT-CRX Bluetooth® Controller/Receiver adds the convenience of backlit, push-button audio controls, so that the streaming device can remain safely tucked away, acting as the hard drive while the MBT-CRX controls the sound output.

A small footprint and a clever, one-hole design makes installation a simple affair, requiring only a single hole for panel mounting. A square, front-mount adaptor plate is also included.
