JL Audio M8W5-SG-TB
M-Series 8-inch Marine Subwoofer Driver for Enclosed Use (200 W, 4 Ω) - Titanium Black Sport Grille
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 M8W5 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 M8W5 is best used with amplifier power in the 75W - 200W range and is optimized to operate in a compact 1.0 cu. ft. (28.3 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 one of our Infinite Baffle Subwoofer Drivers instead.
Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
