Massive bass with cool LED lights

This M7 Series 12" marine subwoofer reflects JL Audio's commitment to awesome sound, cutting-edge styling, and quality engineering. The built-in LED lighting looks terrific and brightens any nighttime cruise. You can choose the color that's right for your boat's interior.

Handles up to 600 watts RMS

This rugged sub can really rock, with a massive magnet and heavy-duty componentry that can handle up to 600 watts RMS. It's tough, too, with a sealed waterproof front and the stylish, UV-resistant titanium-finish sport grille. Add it to your existing system, or use it in conjunction with JL Audio's marine speakers to create a powerful sound system that will really rock the waves.

The motor structure allows for extended cone movement, so your bass will be loud and low, yet precise and smooth. This versatile sub will work in sealed or ported enclosures, but it's optimized for free-air applications, so you can mount it directly into a bulkhead if there's no space for a box.

The coolest cones around

Any sub with built-in lighting is cool, but JL Audio M7 subs are next-level cool. The unique Transflective™ cone is designed to glow evenly when the LEDs shine through, but the cone looks silver when the lights aren't in use, so your sub will look awesome whether the lights are on or off.

The LEDs themselves are mounted to the speaker's frame and illuminate the cone from underneath. This very smart bit of engineering ensures smooth, vibrant light without the “hot spots” you'd notice on lesser LED speakers. It sounds like a subtle difference, but when you see them lit up, you'll understand what a huge improvement this is. You can choose from a variety of fixed lighting colors or control the color and intensity of the lighting with the MLC-RW RGB LED controller (sold separately).

Built for life on the water

Built from the ground up for the marine environment, this rugged subwoofer sports a corrosion-resistant polymer basket that surrounds the internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide outstanding performance, while shrugging off the corrosive effects of sun, salt, and moisture. The UV-resistant grille will stay factory-fresh even after years of outdoor exposure. As an added bonus, you're protected by JL Audio's 2-year warranty.
