JL Audio M10W5-SG-TB 10" Marine Sub 250W Subwoofer

With appropriate system setup, the addition of a subwoofer allows your smaller main speakers to be free of the burden of reproducing low frequencies. This allows your whole system to play louder and to sound cleaner at all listening levels.
Purpose-engineered and built for real marine duty, the M10W5 subwoofers are designed to operate in a compact sealed enclosure. Long excursion capability and rugged suspension systems help produce deep, powerful bass response that will transform your boat's audio system.
The M10W5 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a compact 0.875 cu. ft. (24.8 l) sealed enclosure, or a 1.25 cu. ft. (35.4 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab. If you need a subwoofer driver that operates without a dedicated enclosure, select our M10IB4, instead.
Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
