About the JL Audio M7-12IB-S-GwGw-4

Awesome bass and classic style
Awesome bass and classic style
This M7 Series 12" marine subwoofer reflects JL Audio's commitment to awesome sound, cutting-edge styling, and quality engineering. JL Audio designed this high-performance subwoofer for free-air use or for large sealed enclosures, so you can choose the option that best suits your boat.
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.
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.

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.
Materials: The woofer cone is mica-filled injection-molded polypropylene (IMPP) with UV inhibitors. The surround is synthetic rubber and the woofer uses a marine-grade synthetic fiber spider with a progressive roll design. The basket and grille are UV-resistant polymer; the basket encapsulates the woofer's motor system to prevent corrosion.
Infinite-Baffle Operation: The M7-12IB is optimized for infinite baffle operation so that it can be installed in a variety of locations, without the need for a dedicated enclosure. If an enclosure is used, 3 ft³ is the minimum recommended volume.
Enclosure: If mounting in an enclosure, JL Audio recommends a 3 ft³ sealed or 5 ft³ ported enclosure.
