Vibrant LED Style with Crystal-Clear Sound

Sport models feature built-in RGB LEDs for a stunning, multicolor accent glow that makes your boat or nighttime cruise look as impressive as it sounds. DMA-optimized woofers reduce distortion, enhance transient response, and deliver deep, clear bass that cuts through wind, water, and engine noise. Treated silk dome tweeters provide smooth, crystal-clear highs for pristine audio clarity.

Protected, Versatile Highs

Built-in second-order high-pass tweeter filters with solid-state protection safeguard your speakers while maintaining clean, distortion-free sound. Optimized for high-quality marine amplification, these speakers also work seamlessly with standard marine head-unit power for flexible installation options.
 


 

 


Durable Marine-Grade Audio

Built to withstand harsh saltwater, humidity, and sun exposure, these speakers deliver years of reliable, high-quality performance. Mica-filled IMPP woofers with synthetic rubber surrounds, UV-resistant polymer baskets, and 3/4" silk dome tweeters mounted directly to sport grilles ensure long-lasting durability and optimal sound projection.

Free-Air Ready Speakers with Balanced Sound

Perfect for boat cockpits or bulkhead walls, these 7.7" speakers can be used alone or paired with a subwoofer, requiring at least 2cu.ft. of airspace for optimal performance. Integrated two-way crossovers mounted on the woofer basket ensure seamless synergy between woofer and tweeter for balanced, full-range audio.
