Marine Tested: JL Audio's marine speakers are built to exceed
industry standards for Salt-Fog and UV exposure. They are exposed to ultraviolet
testing chambers to simulate years of sun exposure, and salt fog chambers to simulate
years of exposure to salt-water environments. Corrosion and UV-resistant materials
are used throughout.
Woofers: The MX770-CCX-CG-WH speakers feature injection-molded,
mica-filled polypropylene cone woofers with UV inhibitors, synthetic rubber surrounds,
and precisely engineered dust cap profiles for smooth upper-end response. The woofers
also use marine-grade synthetic fiber spiders with a progressive roll design to
withstand high humidity.
DMA (Dynamic Motor Analysis): DMA is JL Audio's proprietary
method of improving dynamic motor behavior. The DMA optimized, long-excursion
design enhances output, bass extension, and power handling of the speaker.
Tweeters: The speakers feature 3/4" silk dome tweeters
with a specially formulated treatment to withstand UV and salt-spray exposure.
The dome tweeter uses a neodymium magnet for higher efficiency levels and is
Ferrofluid-cooled and damped for improved response and power handling capabilities.
Crossover: The tweeters use 2nd order (12 dB/oct) crossovers
with solid-state tweeter protection to prevent tweeter failure.
Polymer Basket And Grille: The specifically engineered polymer
baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to
Infinite-Baffle Operation: The speakers are designed for
infinite-baffle operation and can be installed in a variety of locations, without
the need for a dedicated enclosure. The woofer is optimized to operate with a
large volume of air behind it (at least 2 cubic feet); operating in less space
will compromise low frequency performance.
