    JL Audio 8" M-Series White Classic Grille Marine Subwoofer Driver - M8W5-CG-WH

    M-Series 8-inch Marine Subwoofer Driver for Enclosed Use (200 W, 4 Ω) - 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 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.

    Features:

    • Dynamic Motor Analysis - DMA Optimized Motor
      JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.
    • Marine Materials / Testing Summary
      The design of marine products requires extensive materials testing to achieve reliability and longevity.
    • Built in U.S.A. with Global Components
      JL Audio's Miramar, Florida loudspeaker production facility is one of the most advanced in the world.
    • Material Used
      • Injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
      • Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
      • Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
      • Gold-plated, marine-grade brass connection terminals
      • Marine-grade stainless steel mounting hardware is included.
