Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

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) to assure you years of durability and high performance.

Woofers: The JL Audio M770-CCS-CG-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 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.
