Bring outstanding sound to your boat
Get more out of your maritime music experience with high-performance JL Audio marine speakers. These M770-CCX-SG-TB 7.7" marine speakers combine durable, marine-ready design with outstanding sound reproduction. You can mount them in your boat's cockpit or bulkhead walls, either as stand-alones or with a subwoofer.
Built for life on the water
These rugged speakers deliver powerful output that'll really 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.

Product Research
Features
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-CCXs feature 7.7-inch diameter woofers that provide 20% more sound radiating area than typical 6.5-inch designs. Each woofer has an injection-molded, mica-filled polypropylene cone 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 of improving dynamic motor behavior. The DMA-optimized long-excursion design enhances the output, bass extension, and power handling of the speaker.
Tweeters: The 1" silk dome tweeters are treated to withstand UV and salt-spray exposure. They use oversized neodymium magnets for higher efficiency levels and are Ferrofluid-cooled and damped for improved response and power handling capabilities.
Crossover: The 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 to help prevent tweeter failures due to abuse. The crossover is mounted directly to the polymer woofer basket, requiring no additional mounting provision.
Polymer Basket And Grille: The Centrex, UV-resistant polymer basket and grille protect the speaker's woofer, tweeter, crossover, and motor structure from the marine environment.
Infinite-Baffle Operation: The speakers are optimized for infinite-baffle operation, so they can be installed in a variety of locations, without the need for a dedicated enclosure.
