JL Audio M-Series Titanium 12" Infinite-Baffle Marine Subwoofer Driver - M12IB6SGTB

M-Series 12-inch Marine Subwoofer Driver for Infinite-Baffle Use (600 W, 4 Ù) - 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.
