This is a genuinely clean alignment case: both the D2 and D4 coil variants land at Qtc 0.71-0.73 in this cabinet, essentially Butterworth for either impedance choice.\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). The motor uses a double-stacked strontium ferrite magnet assembly (123 oz) driving a 65.5mm 4-layer DVC winding on an aluminum former, with Alpine's compound radius curve extended pole geometry (US Pat 6,639,993) and airflow-optimized dual flare pole vent for thermal management under sustained output. 8AWG push terminals with voice-coil configuration jumpers.\u003c\/p\u003e\u003cp\u003eThe 0.50 cubic foot net volume produces a Qtc of 0.71 with the D2 coil and 0.73 with the D4 coil based on Alpine's published T\/S parameters. Both are essentially maximally-flat Butterworth alignments, delivering tight musical output with excellent transient control. Predicted F3 lands at 47 Hz across both coils, with strong cabin gain typical of trunk installations extending that meaningfully lower in-vehicle. Fc lands at 47-48 Hz.\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 cavity for volume tuning and voice-coil cooling, perimeter cross-bracing, and a double-layer 1.5\" front baffle (two 3\/4\" MDF sheets bonded) for maximum baffle rigidity and driver isolation. Wedge geometry angles the cone rear-firing into the trunk at ~20° from vertical for optimum cabin loading. Terminal cup is our Proline X ABS\/carbon-fiber composite pre-wired with 12 gauge OFC.\u003c\/p\u003e\u003cp\u003eBring your own Alpine R2-W10 — mount cutout is direct-fit for either the R2-W10D2 or R2-W10D4. The 8AWG push terminals with VC configuration jumpers on the driver itself let you wire the dual voice coils in series or parallel at the driver, with the terminal cup providing the final connection to your 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":44536221040729,"sku":"PO 10-S W R2","price":239.99,"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_1becc632-b787-4c7b-af36-24e666c27bf4.jpg?v=1787013377","url":"https:\/\/audiointensity.com\/products\/performance-optimized-wedge-sealed-10-enclosure-alpine-r2-w10","provider":"Audio Intensity","version":"1.0","type":"link"}
