The Performance Optimized Wedge Sealed 10" Enclosure for the Prodigy NB5-10 is a musical sealed cabinet built around Prodigy Audio's flagship 10" subwoofer. 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.The Prodigy NB5-10 (NB5-10D2 dual 2Ω or NB5-10D4 dual 4Ω) is a 1000-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.The 0.51 cubic foot net volume was selected to give the NB5-10 an extended musical alignment: the D2 coil lands at Qtc 0.58 (extended, approaching Bessel) and the D4 coil lands at Qtc 0.64 (extended musical, between Bessel and Butterworth) based on Prodigy's published T/S parameters. Both are loose, extended alignments that give the driver plenty of air to work with. Predicted F3 lands in the 49-56 Hz range depending on coil choice, with strong cabin gain typical of trunk installations extending that meaningfully lower in-vehicle.Construction 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.Bring your own Prodigy NB5-10 — mount cutout is direct-fit for either the NB5-10D2 or NB5-10D4.Manufactured in Tullahoma, Tennessee. 1-year enclosure warranty.
