About: JL Audio M7-12IB-C-GwGw-4 M7 Series 12" 600W RMS Marine Subwoofer with White Trim Ring and White Sport Grille 

KING OF BASS

With oversized, overbuilt components and very powerful motor systems, M7s are extreme subwoofers optimized for high-power operation in open-air applications.

• GENERATES STUNNING BASS IN OPEN-AIR APPLICATIONS
• ENGINEERED FOR USE WITHOUT A DEDICATED ENCLOSURE
• GRILLE AND TRIM RING ARE EASILY REMOVABLE FOR PAINTING
• MODELS AVAILABLE WITH PATENTED LED ILLUMINATION
• EXCEEDS INTERNATIONAL STANDARDS FOR SALT FOG AND UV EXPOSURE

INCREDIBLE DISPLACEMENT

Displacement is a direct measure of a subwoofer’s output capability. With more than twice the displacement of most 10-inch subwoofers, the M7-12IB is in a class of its own.

INFINITE BAFFLE DESIGN

M7 marine subwoofers are purpose-engineered to operate without dedicated enclosures, needing only large volumes of air behind them.

HIGH POWERED

The M7 marine subwoofer easily handles up to 600 watts RMS.

DMA-OPTIMIZED WOOFERS

Proprietary motor, suspension and cone modeling systems are employed, resulting in reduced distortion, improved transient performance and stellar bass sound quality.

REAL MARINE DUTY

For long-term use, all models are built to withstand saltwater marine environments and deliver years of listening enjoyment.
