The NB5 Series represents Prodigy's top-tier SQL platform, engineered for extreme output with musical intent, and this wedge gives it the trunk-loading geometry to perform at both.\u003c\/p\u003e\u003cp\u003eThe Prodigy NB5-15 (NB5-15D2 dual 2Ω or NB5-15D4 dual 4Ω) is a 1200-watt RMS subwoofer with 27mm of one-way Xmax at 70% BL, 40mm X-mech forward, and 50mm downward X-mech clearance before soft parts contact hard parts. Motor design features 280 ounces of ferrite, upper and lower aluminum Faraday shorting rings, vented pole with coil-gap radial vents, and a 2.75\" flat-aluminum voice coil. Heavy cast aluminum frame doubles as a heat exchanger. Nomex spiders with double stitched-in tinsel leads, competition-grade treated paper cone, carbon fiber dust cap, and heavy-duty foam surround complete the package.\u003c\/p\u003e\u003cp\u003eThe 1.76 cubic foot net volume was selected to work across both coil options: D2 lands at Qtc 0.66 (musical, extended) and D4 lands at Qtc 0.75 (punchy-musical) based on published T\/S parameters. Both are usable, musical alignments that give the NB5-15 room to breathe while keeping the wedge footprint practical for trunk installations. Predicted F3 lands in the 46-52 Hz range depending on coil choice, with strong cabin gain typical of trunk installations extending that meaningfully lower in-vehicle.\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 ~17° 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 Prodigy NB5-15 — mount cutout is direct-fit for either the NB5-15D2 or NB5-15D4.\u003c\/p\u003e\u003cp\u003eManufactured in Tullahoma, Tennessee. 1-year enclosure warranty.\u003c\/p\u003e","brand":"Proline X","offers":[{"title":"Default Title","offer_id":44532937261145,"sku":"PO 15-S W NB5","price":369.99,"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_0dc95cd9-2b69-41aa-b7fe-360a9f294126.jpg?v=1786932652","url":"https:\/\/audiointensity.com\/products\/performance-optimized-wedge-sealed-15-enclosure-prodigy-nb5-15","provider":"Audio Intensity","version":"1.0","type":"link"}
