7.7″ Speakers, White Classic Grilles

QAR 0.00


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 prevent corrosion.

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.
