Smooth, Powerful, Precision Bass

Experience bass that’s powerful, smooth, and perfectly balanced—ideal for boating, fishing, or dockside entertainment. Its infinite-baffle design requires only moderate air behind the woofer, while DMA-optimized motor, suspension, and cone systems reduce distortion. Optimized for quality amplification, it delivers professional-grade clarity and versatile power handling.

Rugged, Reliable, and Vibrantly Styled

Built for real marine duty, this subwoofer withstands harsh saltwater and UV exposure for years of dependable performance. Sport models feature built-in RGB LED lighting for a vibrant, customizable accent, while marine-grade construction—including mica-filled polypropylene cone, synthetic rubber surround, polymer basket, and stainless steel back plate—resists corrosion and UV damage.

 

Reliable Connections and Flexible Installation

Equipped with gold-plated marine-grade binding posts, this subwoofer ensures secure, long-lasting connectivity in wet, salty conditions. Optimized for infinite-baffle setups and compatible with sealed enclosures (2ft³ recommended), it’s tested in UV and salt fog chambers for durable, long-term marine performance.

  • Upgraded my old marine sub with this one from JL Audio. And when you buy from JL Audio, it means that its really a true upgrade from from before. Really sounds great and the build quality of the marine sub is off the charts. I love also how it looks and although the price can really be painful for the pocket, but its still worth every buck that I paid for it with its overall performance.
