Product Specifications and Features

The JL Audio M6-8IB-S-GmTi-4 is an 8-inch M6 Series marine subwoofer engineered for infinite-baffle (free-air) installations where a traditional subwoofer enclosure isn’t practical. Finished with a Gray Metallic trim ring and a Gunmetal Sport grille with Titanium insert, it delivers tight, controlled low-end while standing up to UV and saltwater exposure.
