JL Audio M7-12IB-S-GmTi-4 12" Marine Infinite-Baffle Subwoofer, 600W RMS, 4Ω, Single 010-03288-00 (93673)

JL Audio M7-12IB-S-GmTi-4 is a 12" marine infinite-baffle subwoofer engineered for enclosure-free bass reinforcement in open-air boats. Its long-excursion motor, large-diameter cone, and robust suspension are optimized for mounting in bulkheads or large cavities where the back wave is vented to free air instead of a dedicated enclosure.

Rated at 600 watts RMS (1200 watts peak) at 4 Ω with 86.7 dB sensitivity, this driver is designed to work with high-power marine mono amplifiers in the 200–600 W RMS range. The titanium Sport grille with gunmetal trim ring provides a darker, technical cosmetic that pairs with JL’s matching Sport grille speakers and tower systems while maintaining marine-grade durability against UV, salt, and spray.
