That is shorter than every other 10 inch enclosure in the Proline X Down Fire line, which makes it the answer when you want 12 inch cone area and have almost no vertical clearance.\u003c\/p\u003e\u003cp\u003eThe Alpine RS-W12 is available as the \u003cstrong\u003eRS-W12D2\u003c\/strong\u003e (dual 2Ω) or \u003cstrong\u003eRS-W12D4\u003c\/strong\u003e (dual 4Ω), both rated 600 watts RMS and 1800 watts peak with 20mm of one-way linear excursion and 54mm of peak-to-peak mechanical travel. The motor is built around a \u003cstrong\u003ehigh-grade neodymium magnet\u003c\/strong\u003e driving a 4 inch high-temperature USA-wound voice coil, with Alpine's DD Linear dual magnetic gap for low distortion at high excursion, a vented coil former for airflow, and motor cooling fins that pull heat off the coil. Die-cast aluminum frame with a black anodized threaded rear mounting frame, aluminum dust cap, and a trim ring compatible with Alpine's RS grille kit. Cone area is 572 cm², the largest in the Down Fire series.\u003c\/p\u003e\u003cp\u003eNeodymium is what makes this cabinet possible. Without a ferrite slug behind the cone the driver occupies almost no internal volume, and Alpine's published displacement of \u003cstrong\u003e0.05 cubic feet\u003c\/strong\u003e for a 12 inch driver is remarkable. A conventional 12 displaces two to four times that.\u003c\/p\u003e\u003cp\u003eThe 0.70 cubic foot net volume sits between Alpine's small and medium sealed recommendations, placing the \u003cstrong\u003eF3 in the low 30 Hz range\u003c\/strong\u003e. For reference, Alpine publishes 35 Hz at 0.60 net, 30.5 Hz at 0.90 net, and 29 Hz at 1.20 net across a full sealed range of 0.6 to 1.5 cubic feet. We build to 0.70 because it is what holds the cabinet at 5.75 inches while still reaching into the low 30s.\u003c\/p\u003e\u003cp\u003eFiring down into the floor, the sealed rolloff meets rising cabin gain below 60 Hz, and in-car response extends well below the published figure.\u003c\/p\u003e\u003cp\u003eConstruction is the full Proline X Performance Optimized platform: ShopSabre CNC-cut Langboard Elite MDF with \u003cstrong\u003eV-groove and dado joinery\u003c\/strong\u003e, perimeter cross-bracing, and a \u003cstrong\u003edouble-layer 1.5 inch front baffle\u003c\/strong\u003e (two 3\/4 inch sheets bonded) for maximum baffle rigidity and driver isolation. Corners are square on Down Fire cabinets. The driver fires down into the floor with the terminal cup \u003cstrong\u003eside mounted\u003c\/strong\u003e, keeping the connection accessible with the cabinet in place. Terminal cup is our Proline X ABS\/carbon fiber composite pre-wired with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own RS-W12D2 or RS-W12D4. Both are dual voice coil, so you set your final impedance at the driver. Alpine's own application guide covers the wiring options for each.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540232106073,"sku":"PO 12-S DF RS","price":249.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1389\/files\/proline-x-micro-series-dual-15-sealed-enclosure-built-for-resonix-gus-15subwoofer-enclosuresproline-x-9360178_9fe93356-ccd0-45b0-b18b-0171fcfbc420.jpg?v=1787106227","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-12-enclosure-alpine-rs-w-shallow","provider":"Audio Intensity","version":"1.0","type":"link"}
