M3 Series 6-1/2" marine speakers 

Exceptional Sound and Stunning Looks from JL Audio

For those looking to upgrade their boat's sound system, JL Audio's M3 Series 6.5-inch marine speakers are a standout choice. These speakers deliver impressive audio quality, combining smart engineering with marine-grade materials to perform reliably even in challenging environments. Whether you're powering across the water or relaxing at the dock, they cut through wind, water, and engine noise with ease. 

Made to Perform on the Water

Each speaker includes a three-quarter-inch treated silk dome tweeter that produces clear, detailed highs. A true two-way crossover ensures that the tweeter and woofer work in perfect harmony, delivering balanced sound at any volume. There’s no need to mount separate crossovers since they’re already built into the speaker frames for easy installation.

Built for Marine Life

These speakers are engineered to handle the elements. JL Audio designs them to meet or exceed industry standards for salt, fog, and moisture resistance. The construction includes UV-resistant grilles and corrosion-resistant polymer baskets that protect the internal components. The marine-grade synthetic fiber spider, injection-molded polypropylene cone, and synthetic rubber surround all contribute to long-lasting performance under the sun and on the water. A two-year JL Audio warranty adds peace of mind to an already durable and powerful speaker system.
