Vibrant Style with Immersive Sound

Sport models feature built-in RGB LEDs for a vibrant, customizable accent glow. DMA-optimized woofers reduce distortion and deliver rich, powerful bass, while treated 3/4" silk dome tweeters provide smooth, crystal-clear highs for a fully immersive marine audio experience.

Protected, Versatile Sound

Built-in second-order high-pass tweeter filters with solid-state protection keep your tweeters safe while preserving crystal-clear audio. Power versatility allows seamless operation with quality amplifiers or standard marine head-unit power for flexible installation.
 


 

 


Durable, High-Impact Marine Audio

Built with marine-grade materials, UV-resistant polymer baskets, and durable synthetic fibers, these 7.7" drivers deliver long-lasting performance in harsh saltwater environments. Their oversized design produces clean, detailed sound that cuts through wind, water, and engine noise for an outstanding outdoor listening experience.

Rugged, High-Performance Marine Speakers

Mica-filled polypropylene cones with synthetic rubber surrounds and UV-resistant polymer baskets protect against water, sun, and debris. Sport-style grilles mount tweeters directly for optimal sound dispersion while safeguarding components. Free-air mounting is ideal for cockpits or bulkhead walls, requiring at least 2?cu.?ft. of airspace for best performance.
