The M3 Series 10" marine subwoofer reflects JL Audio's commitment to top-quality engineering and sound quality. With marine-grade componentry, durable grilles, and outstanding performance, this sub will be a welcome addition to your boat's audio system.

Built for life on the water

Built from the ground up for the marine environment, the M3-10IB sports a corrosion-resistant Centrex® polymer basket that surrounds the sub's internal structure for extra protection. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround provide top performance, while shrugging off the corrosive effects of sun, salt, and moisture. The UV-resistant polymer basket encases and protects the entire structure, plus UV protection ensures that the grilles will stand up to the sun, looking factory-fresh even after years of sun exposure.

Designed for a variety of enclosures

This subwoofer's motor structure allows extended cone movement, so you'll hear bass that's loud and low, yet precise and smooth. The versatile M3-10IB works in sealed enclosures, but it also works well in free-air applications, so you can mount it directly into a bulkhead if there's no space for a box.

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 surrounds are 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 M3-10IB 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 a sealed enclosure is used, 2 ft³ is the minimum recommended volume.
