M6 Loudspeakers fulfill
JL Audio’s commitment to raise the bar with each product generation. The JL
Audio engineering team has completely reinvented the premium marine
loudspeaker, with major improvements in performance, precision and durability.
Offered in multiple sizes and cosmetic options, most models are also available
with a brilliant, new lighting technology.
Advanced Subwoofer Technologies
Offered in 8-inch and 10-inch diameters, M6 subwoofers continue JL Audio’s tradition of building low-frequency drivers that impress, not only with their output capability, but also with the quality and balance of their sound. FEA-optimized motor and suspension designs are optimized for infinite-baffle installation (IB models), or for installation into small sealed enclosures (W models). Choose the right one for your application and it will reward you with powerful, low-distortion sub-bass that takes your marine audio experience to a higher level.
