Get 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-Gw-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 white "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. For optimal performance, each speaker will need at least 2 cubic feet of airspace.

Product highlights:

7.7" 2-way marine speakers with blue LED lighting (pair)
injection-molded, mica-filled polypropylene woofer with synthetic rubber surround
3/4" silk dome tweeter
2-way crossover attached to the woofer basket

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.

3 questions already asked

Can I set the low pass to 16Hz with these speakers?

scott Sep 03, 2023

1 answer

Perhaps we mean 16kHz, in which case the answer is yes, you could set a low pass crossover to block out frequencies over 16kHz. Our advisors are happy to help with your project via online chat or phone at 1-800-324-9695.

zachary Sep 03, 2023 (Staff)

To set the lighting to blue, is the lighting controller needed?

jeff Feb 06, 2023

1 answer

Greetings Jeff, and thank you for your question. A controller is only needed if you need or wanted to change the colors. If all you need is the one color, all you need is a power lead to a 12v switched source, and a ground.

thomas Feb 06, 2023 (Staff)

On the blue light setting are these the same color as the previous MX series? I have a pair of 6.5 & a 10"MX already.

We'd love to know what you think

Audition speakers before you buy

SpeakerCompare simulates the sound of home and car speakers through your headphones. It lets you compare sonic characteristics between speakers so that you can make a more informed shopping decision.

Why selecting your headphones is important

SpeakerCompare tailors your listening experience to the exact headphones you have, so that what you hear is comparable to auditioning speakers side-by-side in person. Knowing which model headphones you’re using lets us remove any sonic coloring from your experience.

Two different listening modes

In an actual listening room, you'd find that some speakers play louder than others when fed the same amount of power. In equal power mode, you'll hear these differences in loudness as they naturally occur between speakers.

In equal volume mode, we've made the loudness of each speaker about the same. This gives you a more direct comparison of subtle voicing differences between speakers.

Nothing beats listening to speakers in your space

SpeakerCompare gives you a sense of the sonic differences. But performance in the real world is affected by the acoustics of your car or home, your choice of amplification, and your source material. We still believe that the gold standard for auditioning speakers is hearing them in your own environment — that’s why we offer a 60-day money-back guarantee.

Our Listening Kit

To help you choose the right speakers, we recommend using Crutchfield’s SpeakerCompare Listening Kit. It includes a pair of studio-quality headphones, and a guide to getting the most out of your session, and a few other necessary items. We’ve carefully chosen the components of this kit to ensure a crystal-clear listening experience. It’s available for a nominal rental fee, and includes a $25 Crutchfield merchandise credit.
