Get more out of your maritime music experience with high-performance JL Audio marine speakers.

Built for marine conditions

These rugged speakers deliver powerful output that'll cut through the combination of wind, water, and engine noise. The weatherproof cone is suspended in a durable synthetic rubber surround for great sound and long life, and the UV-resistant polymer basket  protects the entire structure.

No compromises on sound quality

The 1" treated silk dome tweeters render brilliant highs, and they're mounted directly to the grilles for optimal sound radiation. You'll hear all the details of your music, even when the throttle is forward and you're skimming over the waves. High-quality 2-way crossovers make the woofer and tweeter work in perfect concert. You don't have to worry about mounting the crossovers — they're attached directly to the woofer basket.

Marine Tested: JL Audio's marine speakers go through ultraviolet testing chambers (to simulate years of sun exposure) and salt fog chambers (to simulate years of exposure to salt-water environments.

Woofers: The JL Audio M770-CCX-CG-WH features 7.7-inch diameter woofers that provides 20% more sound radiating area than  typical 6.5-inch designs. The JL Audio Marine Cockpit woofers features an injection-molded, mica-filled polypropylene cone woofer with UV inhibitors, a rubber surround and a precisely engineered dust cap profile for smooth upper-end response. The woofer uses a marine-grade synthetic fiber spider with a progressive roll design and a vented motor structure with a marine grade stainless steel rear diffuser plate.

DMA (Dynamic Motor Analysis): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. The DMA-optimized long-excursion design enhances output, bass extension and power handling of the speaker.

Tweeters: The Marine Cockpit Coaxial speaker features a 1" treated silk dome tweeter with a specially formulated treatment to withstand UV and salt-spray exposure. The dome tweeter uses an oversized neodymium magnet for higher efficiency levels and is Ferrofluid-cooled and damped for improved response and power handling capabilities.

Crossover: The JL audio marine speakers utilize a true 2-way crossover network with 1st order low-pass and 2nd order high-pass circuits. The crossover network also features a polyswitch solid-state tweeter protection which prevents tweeter failures due to abuse and resets automatically. The crossover mounts directly to the polymer woofer basket, requiring no additional mounting provision.

Polymer Basket And Grille: The Centrex, UV-resistant polymer basket and grille protects the speaker's woofer, tweeter, crossover and motor structure from the marine environment.

Infinite-Baffle Operation: The JL Audio M770-CCX-CG-WH  is optimized for infinite-baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure.

Crutchfield Customer Review (What's this?)
This is a nice speaker well built. The sound is comparable to mb quart. These are marine speakers so I expected the sound the to be high and it is, but the clarity should be a little clearer for the price. But even with that said I still think there a good deal, and if they can take the beating they will get in the boat I will recommend them. Only time will tell.
seem to be built well nice one piece design with the built in crossovers
The screws need to be longer ,boat speakers are mounted with backing plates.

Nobody makes a product like JL, pricey but you get what you pay for, these love power especially driven by the mhd900/5 by JL. Many speakers can yell really well, the M770's sing really well.

Hand's down these will finally be the last speakers I install in my boat. After trying about 5 pairs over the years, these have the power capacity and quality to provide lasting high levels of output for extended periods of time. On a boat it's loud at speed and these are the only speakers that can do the job without distortion (the enemy).
I have no complaints or improvements... these are flawless... really!! :)
