JL Audio Marine M770-CCS-SG-WH #91750 – 7.7″ Component System with White Sports Grilles – Pair
JL Audio designed these JL Audio Marine M770-CCS-SG-WH component speakers to deliver powerful sound that’ll cut through the noise when you’re tearing along your favorite stretch of water. Designed to be mounted in your boat’s bulkheads, these rugged speakers use marine-grade stainless steel, synthetic fibers, and UV-resistant polymer baskets to surround and protect their inner workings against humidity and salt. As an added bonus, the UV protection ensures the “Sport” grilles will stay white, looking factory-fresh even after years of sun exposure.
Covering the highs and lows
The system’s two 7.7″ woofers deliver strong bass with stiff mica-injected polypropylene cones suspended in durable synthetic-rubber surrounds, while powerful neodymium magnets cut down on weight without affecting performance. The smooth-sounding treated silk dome tweeters disperse the high frequencies in a wide pattern for excellent stereo imaging. Surface- and flush-mount tweeter housings provide flexible mounting options.
High-quality crossover networks
High-quality 2-way crossover networks route the highs and lows to the appropriate drivers for a winning combination of clean sound quality and speaker efficiency. JL Audio attaches the crossovers to the woofer baskets, so you don’t have to worry about where to mount 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) to assure you years of durability and high performance.
Woofers: The JL Audio Marine M770-CCS-SG-WH 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 synthetic 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 = 0.492″, Mounting Depth = 0.697″, Frame Diameter = 2.382″, Cutout Diameter = 1.855″
Surface Mount: Mounting Height = 1.002″, Frame Diameter = 2.434″, Screw Depth = 0.542″
Crossover: The JL Audio Marine M770-CCS-SG-WH 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.
