It helps systems that sound thin or lack bass by handling the lowest musical frequencies separately from full-range speakers. Its dual 2-ohm voice-coil design gives installers wiring flexibility when matching it to a compatible amplifier.\u003c\/p\u003e\u003cp\u003eThis subwoofer is intended for listeners building or upgrading an Element Ready marine or powersports system. With 200 watts RMS power handling and a 25-250 Hz frequency response, it is suited to controlled bass reinforcement rather than replacing the rest of the audio system. A protective black grille and color-matched trim give it a coordinated appearance in exposed installations.\u003c\/p\u003e\u003cp\u003eThe RM110D2B uses an injection-molded polypropylene cone, Santoprene rubber surround, high-temperature aluminum voice coils, and a double-stacked magnet structure. Its marine-focused construction also includes UV-stable plastic components, corrosion-resistant terminals, insulated silicone lead wires, and stainless mounting hardware. These details support use in environments exposed to sun, moisture, dust, and vibration.\u003c\/p\u003e\u003cp\u003eInstallation options include sealed, vented, and infinite-baffle applications, allowing the enclosure style to be selected for available space and output goals. A sealed enclosure is a practical choice for a compact, controlled installation, while a vented enclosure is designed for greater output around its tuning frequency. Infinite-baffle mounting can work when a properly isolated cavity is available, but it requires a subsonic filter for reliable operation.\u003c\/p\u003e\u003cp\u003eThe RM110D2B is a passive subwoofer and requires an external amplifier, enclosure or suitable infinite-baffle mounting location, speaker wiring, and source signal integration. One 2-ohm dual-voice-coil subwoofer can be wired in series for a 4-ohm load. Pair it with an amplifier that is stable at the final wired impedance and set an active low-pass crossover to suit the rest of the system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e10-Inch Marine Subwoofer:\u003c\/strong\u003e Adds dedicated bass output to compatible marine and powersports systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Supports flexible amplifier-load wiring options.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e200 Watts RMS Handling:\u003c\/strong\u003e Matches appropriately powered external subwoofer amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement-Ready Construction:\u003c\/strong\u003e Uses materials selected for outdoor marine and motorsports exposure.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Installation Types:\u003c\/strong\u003e Works in sealed, vented, or infinite-baffle system designs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Black Grille:\u003c\/strong\u003e Protects the woofer while complementing black installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe RM110D2B combines an injection-molded polypropylene cone with a Santoprene surround, Aramid fiber spider, 2-inch four-layer aluminum voice coils, and a double-stacked magnet motor. UV-stable ASA plastic parts, corrosion-resistant spring-loaded terminals, flexible insulated lead wires, a removable grille assembly, and supplied stainless screws are intended for exposed-use installations. The black finish is designed to coordinate with black marine and powersports speaker systems.\u003c\/p\u003e\u003cp\u003eAllow for a 9.0-inch mounting cutout and 4.4 inches of mounting depth, plus clearance for wiring and the rear of the motor structure. For the manufacturer’s optimum sealed recommendation, use 1.10 cubic feet total internal volume before woofer displacement; the vented recommendation uses 1.45 cubic feet total internal volume before woofer and port displacement. Use an active 80-100 Hz low-pass crossover at 12 dB per octave as recommended, and use a subsonic filter for vented or infinite-baffle configurations.\u003c\/p\u003e","brand":"Rockford Fosgate","offers":[{"title":"Default Title","offer_id":45647663136838,"sku":"RM110D2B","price":209.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61KUxJ0dx-L.jpg?v=1784439050","url":"https:\/\/audiowatt.store\/products\/rockford-fosgate-rm110d2b-10-marine-subwoofer-black","provider":"Audio Watt Store","version":"1.0","type":"link"}
