Towering Performance with Balanced Audio

M3 speakers deliver powerful, projected sound for wakeboard towers, tubular structures, or flat-mounted decks, cutting through engine noise and outdoor elements. DMA-optimized woofers reduce distortion, improve transient response, and produce deep, clean bass for an immersive listening experience on water or trails. Lightweight silk dome tweeters provide smooth high-frequency response and crystal-clear detail for full, balanced audio.

Protected, Versatile Highs

Built-in second-order high-pass tweeter filters with solid-state protection safeguard your tweeters while maintaining consistent, clear sound. Optimized for high-quality marine amplifiers and compatible with standard marine head-unit power—including systems like MediaMaster® 55 or Fusion® MS-RA210—for flexible installation.
 


 

 


Durable Marine Audio with Crisp Sound

Built with marine-grade stainless steel, UV-resistant polymer baskets, and synthetic fibers, these speakers resist saltwater, humidity, and sun exposure for long-lasting performance. Mica-filled polypropylene woofers with durable rubber surrounds, paired with 3/4" silk dome tweeters mounted to grilles, deliver clear, powerful sound even at high volumes.

Clamp-Ready, Rugged Marine Speakers

Injection-molded enclosures with decorative aluminum logo caps are compatible with JL Audio clamp systems (sold separately), keeping wiring secure, elevated, and dry. Rugged yet stylish design ensures your speakers look great while withstanding harsh marine conditions for years of reliable outdoor enjoyment.
