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
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.
