Fusion Marine FM Series 10-Inch Flush-Mount Subwoofer — IP65 Weatherproof

Deliver deep, punchy bass on the water with the Fusion FM Series 10-inch flush-mount marine subwoofer. Designed for a sleek, minimal profile, it threads into your vessel’s design with an ultra-low installation depth that keeps sightlines clean while still producing impactful low end. Built to endure harsh marine environments, the FM Series carries IP65 weatherproof protection for front ingress against dust and water when mounted correctly, so your music sounds consistent from dawn patrol to after-dock sunset.

Why the FM Series stands apart

Fusion engineers this subwoofer around a True-Marine ethos, concentrating on durability, reliability, and marine-specific performance. The result is a bass solution that survives salt spray, UV exposure, temperature swings, and the vibrations of life on the water, paired with a clean, minimal aesthetic that complements modern helm stations. A robust 3-year marine warranty backs this confidence, offering long-term peace of mind for weekend cruisers and year-round coastal mariners alike.

What you get in real-world performance

The FM Series 10-inch sub delivers a balanced, controlled bass footprint ideal for creating a dedicated 2.1 audio zone aboard your boat. With 400W peak power and 120W RMS handling, it hits tight lows without overpowering midrange clarity, making dialogue and music both intelligible and immersive. It’s specified for a 30 Hz to 2 kHz bandwidth, delivering deep sub-bass extension while staying responsive to the midbass punch that drives in-cabin and cockpit experiences. The 4-ohm nominal impedance pairs well with compact marine amplifiers, ensuring efficient power delivery in tight electrical environments.

Design and build that matter on the water

At the heart of the FM Series is a durable polypropylene cone with a rubber surround, engineered to withstand the marine climate and provide reliable cone motion under varying loads. The flush-mount design favors a sleek, unobtrusive exterior—perfect for boats where space is premium and aesthetics matter as much as sound. The enclosure-free, low-profile geometry reduces mounting depth requirements while maximizing audible impact from a 10-inch driver, allowing for flexible speaker layouts in cabins, cockpits, or helm consoles.

Ideal use scenarios

• Enhance a compact 2.1 marine audio setup in a cockpit or cabin without bulky enclosures.
• Pair with FM Series full-range speakers for a cohesive on-water audio system that stays distinct from engine noise and spray.
• Install in boats where a low visual profile and durable construction are priorities, such as day boats, center consoles, and tenders used in saltwater environments.

Whether you’re cruising the marina, anchoring offshore, or entertaining guests on deck, this subwoofer delivers reliable bass performance that translates into a more engaging, music-forward boating experience.
