JL Audio 12" M-Series Titanium Marine Subwoofer Driver - 91839
- M-Series 12-inch Marine Subwoofer Driver for Infinite-Baffle Use (600 W, 4 Ω) - Titanium Classic 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.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
