At \u003cstrong\u003e7.4375 inches tall\u003c\/strong\u003e on a 30 by 15 inch footprint, it is shorter than most single-driver dual-capable enclosures on the market and delivers roughly 6 dB more maximum output than one RS-W10 in the same alignment.\u003c\/p\u003e\u003cp\u003eEach Alpine RS-W10 is available as the \u003cstrong\u003eRS-W10D2\u003c\/strong\u003e (dual 2Ω) or \u003cstrong\u003eRS-W10D4\u003c\/strong\u003e (dual 4Ω), 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 uses 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, and motor cooling fins. Die-cast aluminum frame, black anodized threaded rear mounting frame, aluminum dust cap, and a trim ring compatible with Alpine's RS grille kit.\u003c\/p\u003e\u003cp\u003eThis enclosure follows the Proline X standing design rule for dual sealed builds: \u003cstrong\u003etwo fully separate chambers\u003c\/strong\u003e divided by a bonded full-height 3\/4 inch MDF panel, giving each driver its own dedicated airspace. Two drivers sharing one sealed volume interact acoustically, with each driver's compression phase becoming the other's pressure environment, which smears transient response and blurs the alignment each would have on its own. Separate chambers eliminate that entirely.\u003c\/p\u003e\u003cp\u003eTotal internal gross volume is 1.084 cubic feet split into two chambers, giving \u003cstrong\u003e0.50 cubic feet net per driver\u003c\/strong\u003e after Alpine's published 0.04 cubic foot displacement. That matches Alpine's own small-volume sealed recommendation exactly, where they publish an \u003cstrong\u003eF3 of 32 Hz\u003c\/strong\u003e. Each driver sees the same alignment as the single-driver Down Fire cabinet, so this is the same sound with twice the cone area behind it.\u003c\/p\u003e\u003cp\u003eNeodymium is what keeps this cabinet as short as it is. Two conventional ferrite 10s in separate chambers would need considerably more height for the same net volume per driver. At 0.04 cubic feet displaced each, these two drivers together take up less internal room than a single ferrite 10 typically does.\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 \u003cstrong\u003edouble-layer 1.5 inch front baffles\u003c\/strong\u003e (two 3\/4 inch sheets bonded) at both driver positions. Corners are square on Down Fire cabinets. Both drivers fire down into the floor, and \u003cstrong\u003eone side-mounted\u003c\/strong\u003e Proline X ABS\/carbon fiber composite terminal cup serves both chambers, fed in parallel to both driver positions with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own pair of RS-W10D2 or RS-W10D4 subwoofers. Both are dual voice coil, so you set your final impedance at the drivers. Wire both drivers identically.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44540239904857,"sku":"PO 10D-S DF RS","price":279.99,"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_2dd65716-ed15-44e3-89e1-b4249563d27c.jpg?v=1787106561","url":"https:\/\/audiointensity.com\/products\/performance-optimized-down-fire-sealed-dual-10-enclosure-alpine-rs-w-shallow","provider":"Audio Intensity","version":"1.0","type":"link"}
