The oversized 7.7-inch design of the M6-770X coaxial results in increased efficiency (more output for a given amount of power). Combine that advantage with long excursion and excellent power handling and you have a speaker system truly capable of playing loud and clear in a powerboat at speed.


A 1-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. You will appreciate the clean, articulate high-frequency response of the M6 dome tweeter, especially at higher volume levels.

A true 2-way passive crossover network is built into the terminal assembly to protect it from vibration and corrosion.

Although M6-770X Coaxial Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 40-200 W of continuous power per channel.

Powerful sound from durable speakers

JL Audio’s line of M6 marine speakers brings a whole new level of sound and style to your boat. These powerful 7.7” speakers combine innovative design with rugged, marine-ready componentry to give you outstanding audio performance that really cuts through the wind, water, and engine noise.

High-performance componentry

The 1″ treated-silk dome tweeter renders brilliant highs, and true 2-way crossover ensures that the woofer and tweeter work in perfect concert. You’ll hear all the details of your music, even when the throttle is forward and you’re skimming over the waves. You don’t have to worry about mounting the crossovers because they’re attached to the speaker frames.

Technology: 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

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, JL Audio’s 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 JL Audio’s commitment to state-of-the-art assembly technology, allows the skilled workforce to efficiently build JL Audio products to extremely high-quality standards, right here in the U.S.A.

Since most of JL Audio’s premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, JL Audio find it is vital that the people who designed them have close access to the people manufacturing them.
