Product Specifications and Features

The JL Audio M7-12IB-S-GMTI-4 is a genuine M7-Series 12-inch marine subwoofer driver engineered for infinite-baffle (free-air) installations where maximum output and durability are required. Featuring a gunmetal trim ring with a titanium Sport grille, it’s built for harsh marine environments and delivers powerful, controlled bass without the need for a dedicated enclosure when mounted to a large air volume behind the driver.

  • Preferred use: Infinite-baffle / free-air with at least 3.0 cu. ft. (84.95 L) air volume behind the driver
  • Sealed enclosure (optional): minimum 2.0 cu. ft. (56.6 L); optimum 3.0 cu. ft. (70.8 L)
  • Key dimensions: overall Ø 356 mm (14"); cutout Ø 306 mm (12.0625"); mounting depth ~202–204 mm (7.94–8.03")
