JL Audio M7-12IB-S-GmTi-4 12" Marine Infinite-Baffle Subwoofer, 600W RMS, 4Ω, Single 010-03285-00 (93670)

JL Audio M7-12IB-S-GmTi-4 is a 12" marine infinite-baffle subwoofer engineered for enclosure-free bass reinforcement in open-air marine systems. The long-excursion motor assembly, oversized cone, and heavy-duty suspension are tuned for bulkhead or cabinetry mounting where the rear wave vents to free air rather than a sealed or ported box.

Rated at 600 W RMS (1200 W peak) at 4 Ω with ~86.7 dB sensitivity, this driver pairs best with high-power marine mono amplifiers in the 200–600 W RMS range. The gunmetal trim ring combined with the titanium Sport grille provides a darker, performance-oriented cosmetic. Marine-grade materials resist UV, salt, spray, and vibration for long-term reliability in demanding offshore environments.
