About the JL Audio M3-770X-S-GM-I

JL Audio Built In USAGet the LED out

Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These M3-770X-S-Gm-i 7.7" marine speakers combine durable, marine-ready design, outstanding audio performance, and the cool look of subtle blue lighting. Supplied with plenty of power, these oversized speakers can overcome that wicked combination of wind, water, and engine noise. Plus, the built-in LED lighting brightens up any nighttime cruise.

Tough enough for life on a boat

The weatherproof cone is suspended in a durable synthetic rubber surround for great sound and long life, and the UV-resistant polymer basket surrounds and protects the entire structure. The 3/4" treated silk dome tweeter renders brilliant highs, and it's mounted directly to the gunmetal "Sport" grille for optimal sound radiation. The high-quality 2-way crossover mounted to the woofer basket ensures the woofer and tweeter work in perfect concert.

Ideal for free-air mounting

You can mount these sharp-looking 7.7" speakers in your boat's cockpit or bulkhead walls, either as stand-alones or in conjunction with a subwoofer.

Product Research

Features

Marine Tested: JL Audio's marine speakers are tested in ultraviolet chambers to simulate years of sun exposure, and salt fog chambers to simulate years of exposure to salt-water environments.

LEDs: There are six multi-color LEDs in the back of the tweeter casing, to create a glow on the woofer cone. Depending on what combination of LED wires is connected, they can light red, green, blue, yellow, pink, aqua, or white. A 12 volt power supply is needed to turn the LEDs on. JL Audio recommends a 150 mA fuse on the LED power lead of each speaker. The LEDs can also be controlled using JL Audio's MLC-RC controller (item number 13699816, sold separately).

Woofers: The woofer cones are injection-molded, mica-filled polypropylene with UV inhibitors, synthetic rubber surrounds, and marine-grade synthetic fiber spiders.

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: Each speaker features a grille mounted ¾" treated silk dome tweeter with a specially formulated treatment to withstand the marine environment. The tweeters use neodymium magnets for higher efficiency levels and are Ferrofluid-cooled and damped for improved response and power handling capabilities.

Crossover: The woofers use a natural roll-off and the tweeter crossovers are 12 dB/octave. The crossover also features a polyswitch solid-state tweeter protection circuit.

Polymer Basket And Grille: The baskets and grilles are UV-resistant polymer. The baskets encapsulate the woofers' motor systems to prevent corrosion.

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.

Power Handling: JL Audio recommends two RMS power figures for this model; 70 watts RMS continuous power handling and 20-140 recommended amplifier power. We've listed the more conservative 70 watts RMS in the specs table.
