JL Audio M7-12IB-S-GwGw-i-4 is a 12" marine infinite-baffle subwoofer engineered for enclosure-free bass reinforcement in open-air marine systems. Its long-excursion motor, oversized cone, and robust suspension are optimized for mounting in bulkheads or large cavities where the rear wave vents to free air rather than a sealed or ported enclosure.
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 Gloss White Sport grille with white trim ring integrates Transflective™ RGB LED lighting behind the cone, providing uniform illumination compatible with JL MLC-RW controllers (sold separately). Marine-grade materials resist UV, salt, and spray for long-term reliability.
