{"product_id":"rockford-fosgate-r2sd212","title":"Rockford Fosgate R2SD2-12 12\" Shallow DVC Subwoofer","description":"\u003cp\u003eThe Rockford Fosgate R2SD2-12 is a 12-inch shallow-mount subwoofer designed for vehicle installations where conventional deep subwoofers will not fit. Its low-profile design helps add bass to trucks, compact vehicles, and custom enclosures with limited mounting depth. The dual 2-ohm voice coils provide flexible wiring options when matching an amplifier.\u003c\/p\u003e\u003cp\u003eRated for 250 watts RMS and 500 watts peak, this Prime R2 subwoofer is intended for systems seeking controlled low-frequency output without requiring a large enclosure. Its 43-250 Hz frequency-response specification supports sub-bass and mid-bass reinforcement in a properly configured system. The 85 dB sensitivity rating reflects a design focused on shallow-installation practicality rather than maximum efficiency.\u003c\/p\u003e\u003cp\u003eThe R2SD2-12 uses a monolithic injection-molded polypropylene cone and a high-density compressed poly-foam surround. These materials are paired with a poly-cotton spider intended to support cone movement while resisting fatigue. A high-temperature copper voice coil on an aluminum former helps the driver manage sustained power within its rated range.\u003c\/p\u003e\u003cp\u003eIts motor structure incorporates an extended pole and bumped, vented backplate, while the stamped-steel frame supports the shallow basket format. Spider venting helps move air around the motor assembly during operation. All-metal compression terminals provide a secure connection point for speaker wire.\u003c\/p\u003e\u003cp\u003eThis subwoofer is suited primarily to sealed-box applications, with a manufacturer-recommended sealed enclosure volume of 0.90 cubic feet. It can also be used in a properly designed vented enclosure when more enclosure space is available. Pair it with an amplifier whose stable impedance capability and RMS output match the final voice-coil wiring configuration.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShallow-Mount 12-Inch Design:\u003c\/strong\u003e Fits installations with limited mounting-depth clearance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e250 Watts RMS Handling:\u003c\/strong\u003e Supports amplifier matching for sustained bass output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual 2-Ohm Voice Coils:\u003c\/strong\u003e Provides wiring flexibility for compatible amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePolypropylene Cone:\u003c\/strong\u003e Offers a rigid, moisture-resistant cone material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVented Motor Structure:\u003c\/strong\u003e Helps manage heat around the motor assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSealed-Box Optimization:\u003c\/strong\u003e Supports compact sealed enclosures for controlled bass.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe R2SD2-12 combines a heavy-gauge stamped-steel frame with a polypropylene cone, poly-foam surround, attached poly-cotton spider, and aluminum voice-coil former. It also includes a semi-flexible PVC integrated trim ring. The design uses flexible stitched lead wires and high-temperature bonding at the neck joint to support repeated cone movement.\u003c\/p\u003e\u003cp\u003eConfirm that the enclosure provides at least the required 11.25-inch cutout clearance and 3.60-inch mounting depth before installation. For a sealed system, use the recommended 0.90-cubic-foot enclosure target; a vented design requires 1.79 cubic feet, a 4-inch port, and the specified port length. Wire the two 2-ohm voice coils only in a configuration supported by the amplifier, and use an active low-pass crossover around 80-100 Hz at 12 dB per octave as recommended in the owner documentation.\u003c\/p\u003e","brand":"ROCKFORD FOSGATE","offers":[{"title":"Default Title","offer_id":45768042283199,"sku":"R2SD212","price":82.94,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0533\/6252\/4351\/files\/71mqLlMecUL.jpg?v=1782270384","url":"https:\/\/nsidistributor.com\/products\/rockford-fosgate-r2sd212","provider":"NSI Audio Distributing","version":"1.0","type":"link"}
