JL Audio M12IB6-SG-TB: 12-inch (300 mm) Marine Subwoofer Driver, Titanium Sport Grille, 4


M-Series 12-inch Marine Subwoofer Driver for Infinite-Baffle Use (600 W, 4 ) - Titanium Sport Grille

Engineered as the reference standard for marine subwoofer performance, the M12IB6 is capable of producing staggering amounts of jaw-dropping bass in infinite-baffle applications.

Built to withstand real-world marine duty, this M12IB6 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.

The M12IB6 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.
