JL Audio M7 12" Marine Subwoofer Driver - 010-03285-00

JL Audio 93669 M7 12-inch Marine Subwoofer Driver in Gloss White

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.

Features

• Dynamic Motor Analysis - DMA Optimized Motor
  JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
• Marine Materials / Testing
  Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.
  • Materials Used:
    • injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
    • Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
    • Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
    • Gold-plated, marine-grade brass connection terminals
    • Marine-grade stainless steel mounting hardware is included.
• Built in U.S.A. with Global Components
  At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.
  Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. The following JL Audio products are built in our Miramar, Florida factory, with global components:
  • Subwoofers: W7, W6v3, TW5v2, TW3, TW1, W3v3
  • Enclosed Car Subwoofers: Stealthbox®, PowerWedge™, ProWedge™, H.O. Wedge™ & MicroSub™ Enclosed Subwoofers
  • Marine Loudspeakers, Marine Subwoofers and Marine Enclosed Loudspeakers
  • Home Subwoofers: Dominion™, E-Sub, Fathom® and Gotham®

Footnotes:

• *Frontal grille protrusion measured from mounting surface
• **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”.
