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.
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.
