JL Audio M6-8IB-S-GwGw-i-4 M6 Series 8" marine feree air subwoofer with RGB LED (Gloss White Sport Grille), 4 Ω
M6 8-inch Marine Subwoofer with Transflective™ LED Lighting for Infinite-Baffle Use (200 W, 4 Ω) - Gloss White Trim Ring, Gloss White 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 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. This model also features the added visual impact of JL Audio’s Transflective™ RGB LED lighting, a patent-pending technology that emits a smooth lighting effect through the woofer cone, with a choice of several lighting colors. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.
The M6-8IB is best used with amplifier power in the 50W - 200W range and is optimized to operate with a large volume of air behind it (at least 1.5 cu. ft. / 42.5 l). If you prefer to use a dedicated enclosure, refer to one of the suggested designs located in the Specifications section for optimum performance.
Like all JL Audio marine speakers, this driver is built to withstand a real saltwater marine environment and deliver years of listening enjoyment.
