JL Audio M770-CCS
7.7" marine component speaker system
Our take on the JL Audio M770-CCS by Crutchfield's Ken Nail
Go for the best possible sound on your boat with the high-performance JL Audio M770-CCS 7.7" marine component speaker system. The system combines durable, marine-ready design with the outstanding sound reproduction you can only get with separate components. You can mount the woofers in your boat's cockpit or bulkhead walls, while the tweeters include all hardware for flush- or surface-mounting.
The oversized 7.7" woofers punch out powerful low-frequency response, for a full sound in your listening area even without a subwoofer. Super-light neodymium magnets drive the woofer motor, moving a weatherproof cone suspended in a durable synthetic rubber surround. The UV-resistant polymer basket encases and protects the entire structure.
The 1" treated silk dome tweeters disperse smooth-sounding highs in a wide pattern, for outstanding imaging and strong stereo separation. High-quality 2-way crossovers allow the woofer and tweeter to work in perfect concert, and here's a smart idea the crossovers are mounted directly to the woofer's basket, so you don't have to spend time and energy figuring out where to put them.

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-CCS-W Marine Component System features 7.7-inch diameter woofers that provides 20% more sound radiating area than typical 6.5-inch designs and also benefit from an oversized 1.25-inch diameter voice coil for additional power handling. 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 Component System features separately mounted 1" treated silk dome tweeters with a specially formulated treatment to withstand UV and salt-spray exposure. The dome tweeters use an oversized neodymium magnet for higher efficiency levels and are Ferrofluid-cooled and damped for improved response and power handling capabilities. The tweeters come supplied with surface and flush mount fixtures.
Flush Mount: Mounting Height = 0.5625", Mounting Depth = 0.835", Frame Diameter = 2.382", Cutout Diameter = 1.855"
Surface Mount: Mounting Height = 1.005", Frame Diameter = 2.445", Screw Depth = 0.5625"
Crossover: The JL Audio Marine Component System utilizes 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 crossovers are mounted directly to the woofer's polymer basket, requiring no additional mounting provisions.
Polymer Baskets And Grilles: The Centrex, UV-resistant polymer basket and grilles protect the component system's woofers, crossovers, motor structure and tweeters from the marine environment.
