JL Audio M7-12IB-C-GwGw-4
12-inch (300 mm) Marine Subwoofer Driver, Gloss White Trim Ring, Gloss White Classic Grille, 4 Ω
General Features:
M7 12-inch Marine Subwoofer for Infinite-Baffle Use (600 W, 4 Ω) - Gloss White Trim Ring, Gloss White Classic Grille
Engineered as the reference standard for marine subwoofer performance, the M7-12IB is capable of producing staggering amounts of jaw-dropping bass in infinite-baffle applications.
Built to withstand real-world marine duty, this M7-12IB is designed to operate without a dedicated enclosure. It boasts a monstrous 4-inch voice coil and rugged suspension system to deliver outstanding linear excursion for high output and power handling.
M7-12IB is best used with amplifier power in the 200W – 600W range and is optimized to operate with a large volume of air behind it (at least 3 cu. ft. / 84.95 l).
Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
