JL Audio M6-8IB-L-GwSw-4 is an 8" marine subwoofer built for free-air, infinite-baffle, sealed, or ported installs where deep, controlled bass is required. Designed with rugged marine-grade materials, this M6 series driver handles up to 200 watts RMS and is optimally voiced for real-world marine environments with UV-resistant grilles and corrosion-resistant hardware.
The injection-molded mica-filled polypropylene cone and synthetic rubber surround provide bass articulation with low distortion across a wide range of levels, while the polymer basket and marine-grade spider ensure long-term durability. With a nominal 4Ω impedance and sensitivity around 86.8 dB, this sub complements full-range JL marine systems and pairs with dedicated amplifiers for impactful low-frequency extension.
