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).
Woofers: The JL Audio M770-CCXs feature 7.7-inch diameter
woofers that provide 20% more sound radiating area than typical 6.5-inch designs.
Each woofer has an injection-molded, mica-filled polypropylene cone with UV
inhibitors, a 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 of improving dynamic motor behavior. The DMA-optimized long-excursion design
enhances the output, bass extension, and power handling of the speaker.
Tweeters: The 1" silk dome tweeters are treated to
withstand UV and salt-spray exposure. They use oversized neodymium magnets
for higher efficiency levels and are Ferrofluid-cooled and damped for improved
response and power handling capabilities.
Crossover: The speakers utilize 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 to help prevent tweeter failures
due to abuse. The crossover is mounted directly to the polymer woofer basket, requiring
no additional mounting provision.
Polymer Basket And Grille: The Centrex, UV-resistant polymer
basket and grille protect the speaker's woofer, tweeter, crossover, and motor
structure from the marine environment.
Infinite-Baffle Operation: The speakers are optimized for
infinite-baffle operation, so they can be installed in a variety of locations,
without the need for a dedicated enclosure.
