JL Audio M7-12IB-C-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, large cone area, and heavy-duty suspension are optimized for bulkhead and cabinetry mounting where the rear wave is vented to free air rather than contained in a sealed or ported enclosure.
Rated at 600 W RMS (1200 W peak) at 4 Ω with ~86.7 dB sensitivity, this driver is intended for high-power marine mono amplifiers in the 200–600 W RMS range. The Gloss White Classic grille with white trim ring incorporates Transflective™ RGB LED lighting behind the cone, providing uniform illumination compatible with JL’s MLC-RW LED controller (sold separately). Marine-grade materials resist salt, spray, vibration, and UV exposure for long-term reliability.
