About the JL Audio M3-770X-S-Gm
Cool, big marine sound
Cool, big marine sound
Having toured JL Audio myself, I can tell you these guys take two things very seriously — great sound and life on the water. These oversized M3-770X-S-Gw 7.7" marine speakers make both possible, thanks to excellent design and the most durable materials.
Supplied with plenty of power, these speakers can overcome that wicked combination of wind, water, and engine noise. The weatherproof mica-filled polypropylene cone is suspended in a durable synthetic rubber surround for long excursion and impactful sound. The UV-resistant polymer basket surrounds and protects the entire structure.
The 3/4" treated silk dome tweeters deliver brilliant highs, and they're mounted directly to the sport-style grilles for optimal sound radiation. Even in the roughest waters, you'll be able to enjoy the fine detail of your favorite tunes.
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. For optimal performance, each speaker will need at least 2 cubic feet of airspace.

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.
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.
