Description


Powerful Bass for Enclosed Powersports Applications

Dropping heavy, authoritative bass into a boat or off-road vehicle requires a dedicated low-frequency driver built specifically for the chaos of the outdoors. The Diamond Audio MS104SL is a rugged 10" marine subwoofer engineered to produce massive output whether installed in a tight sealed box or a larger vented enclosure. Handling a continuous 200 watts RMS and peaking at 400 watts, this dynamic powerhouse easily absorbs high current to deliver deep, thumping bottom-end that cuts right through roaring engines, crashing waves, and howling winds.

Generating huge volume is only half the acoustic equation; maintaining precise control over those low frequencies is what separates premium equipment from the rest. To maximize efficiency, this MOTORSPORT series unit utilizes a super high-energy neodymium motor structure combined with an impressive 12.3mm Xmax. This allows the fully waterproof polypropylene cone to achieve massive physical excursion, pushing out tight, distortion-free bass transients. To completely elevate the visual atmosphere of your nighttime rides or dockside parties, it features a crisp white grill with fully integrated RGB LED lighting that instantly sets a vibrant, customizable mood.

Exposing your top-tier audio investment to salt spray, thick mud, and intense summer sun demands absolute structural resilience. Manufactured to strict IP65 marine-grade standards, this subwoofer boasts a UV-treated ASA high-impact thermoplastic construction that aggressively repels water and prevents the frame from fading, warping, or cracking over time. Requiring a standard mounting diameter of 9.22" and a highly manageable mounting depth of just 4.74", this heavy-hitting driver securely locks into your favorite recreational vehicle, guaranteeing a competition-ready soundstage engineered entirely to survive extreme outdoor abuse.
