JL Audio M6-10IB-C-GwGw-4 Subwoofer Classic M6 10-inch Marine Subwoofer Driver for Infinite-Baffle Use (250 W, 4 Ω) - Gloss White Trim Ring, Gloss White Classic 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 M6 infinite-baffle woofers are designed to operate without a dedicated enclosure. Long excursion capability and rugged suspension systems help produce deep, powerful bass response that will transform your boat's audio system.
The M6-10IB is best used with amplifier power in the 75W - 250W range and is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 56.6 l). If you need a subwoofer driver that operates in a small sealed enclosure, select our M6-10W, instead.
Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
