JL Audio M3 10-inch Marine Subwoofer for Infinite Baffle – Gloss White Sports Grille (4 Ω)
Legendary Sub-Bass Performance. Sporty Styling. High-Value Infinite Baffle Architecture.
Add deep, impactful low-frequency extension to your boat without giving up valuable dry storage space or stretching your budget. The JL Audio M3-10IB-S-Gw-4 is a high-performance 10-inch marine subwoofer purpose-engineered by the undisputed leaders in open-water audio to deliver rich, tight sub-bass punch in a highly efficient design.
Featuring an athletic, multi-spoke Gloss White Sports Grille, this driver seamlessly matches modern sport boats, center consoles, and standard white fiberglass decks. As a dedicated Infinite Baffle (IB) driver, it is acoustically optimized to operate perfectly without a custom subwoofer box. Instead, it utilizes the open air inside your boat's bulkheads, seat bases, or side panels to act as a giant natural speaker cabinet, reducing installation weight, time, and custom fabrication expenses.

True Marine® Certified Durability: Fully armored against the open sea. Utilizing advanced UV-resistant polymer baskets and marine-grade synthetic fibers, the M3 line offers complete defense against saltwater corrosion, moisture ingress, and sun fading.
