Two fully separate chambers, one wedge, +6 dB of headroom over a single-driver setup - and per-chamber alignment lands right at Butterworth for both the D2 and D4 coil variants.\u003c\/p\u003e\u003cp\u003eThe Alpine R2-W10 (R2-W10D2 dual 2Ω or R2-W10D4 dual 4Ω) is a 750-watt RMS subwoofer with 20mm of one-way Xmax, a reinforced parabolic pulp\/Kevlar cone with PP\/ceramic dust cap, high-amplitude multi-roll Santoprene surround (US Pat 8,208,677), progressive spider with reinforced-layer tinsel leads (US Pat 6,810,988), and custom cast aluminum frame with perimeter venting and airflow management (US Pat 7,684,585). Double-stacked strontium ferrite motor (123 oz) driving a 65.5mm 4-layer DVC winding on an aluminum former.\u003c\/p\u003e\u003cp\u003eThis dual enclosure follows the Proline X standing design rule for dual sealed enclosures: two fully separate chambers divided by a bonded full-height, full-depth 3\/4\" MDF panel, giving each driver its own dedicated air volume and its own terminal cup. This eliminates cross-chamber acoustic coupling and cabin-pressure interference between drivers, delivering the tight, controlled sealed alignment character that individual chambers preserve.\u003c\/p\u003e\u003cp\u003eTotal internal gross volume is 1.16 cubic feet, split into two 0.58 cubic foot chambers. Each chamber lands at 0.50 cubic feet net after 0.08 cubic feet of driver displacement, producing Qtc 0.71 with the D2 coil and Qtc 0.73 with the D4 coil - essentially textbook Butterworth for either impedance choice. Predicted F3 lands at 47 Hz per driver, with dual drivers producing +6 dB of maximum output over a single driver in the same alignment.\u003c\/p\u003e\u003cp\u003eConstruction is the full Proline X Performance Optimized platform: ShopSabre CNC-cut Langboard Elite MDF stack-fab layers, all four corners radiused 3\" viewed top-down, precision-milled magnet cavities for volume tuning and voice-coil cooling on each driver, perimeter cross-bracing, and double-layer 1.5\" front baffles (two 3\/4\" MDF sheets bonded) on both driver positions. Wedge geometry angles both cones rear-firing into the trunk at ~20° from vertical for optimum cabin loading. Two independent Proline X ABS\/carbon-fiber composite terminal cups, one per chamber, pre-wired with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own pair of Alpine R2-W10 subwoofers - mount cutouts are direct-fit for either the R2-W10D2 or R2-W10D4. Run both drivers at matched impedance. The R2's 8AWG push terminals with VC configuration jumpers let you wire each driver's dual voice coils in series or parallel at the driver, then wire the two drivers together externally at the amplifier.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44536357159001,"sku":"PO 10D-S W R2","price":309.99,"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_e8a0402f-e938-4993-ab13-9d5ecc0563c7.jpg?v=1787014889","url":"https:\/\/audiointensity.com\/products\/performance-optimized-wedge-sealed-dual-10-enclosure-alpine-r2-w10","provider":"Audio Intensity","version":"1.0","type":"link"}
