Built with a focus on efficiency and linear control, the NB2-8d4 features an optimized motor assembly that provides a balanced Qts of 0.448, making it highly effective in both compact ported and sealed applications. With an FS of 37.33Hz, this driver is tuned to deliver authoritative low-end extension that belies its 8-inch diameter.\u003c\/p\u003e\n\n\u003ch2\u003eThermal Management and Motor Integrity\u003c\/h2\u003e\n\u003cp\u003eReliability is driven by a robust motor structure featuring a BL of 17.879, ensuring the Dual 4-ohm voice coil maintains absolute control over the 117.4g moving mass. The NB2 series utilizes a vented backplate to facilitate direct cooling of the coil assembly, mitigating thermal compression during extended high-output sessions. This thermal stability, combined with a 14mm Xmax, allows the NB2-8d4 to maintain its sonic character and \"slam\" even when pushed toward its mechanical limits in demanding daily-driver environments.\u003c\/p\u003e\n\n\u003ch2\u003eIntegration-Focused Footprint\u003c\/h2\u003e\n\u003cp\u003eDesigned for the modern installer, the NB2-8d4 features a mounting depth of exactly 5.000 inches, making it a viable solution for custom enclosures where traditional high-excursion woofers are too deep. The 7.250-inch cutout and 8.500-inch overall diameter allow for seamless fitment into standard 8-inch baffles. Equipped with heavy-duty terminals and a displacement of only 0.07 ft³, the NB2-8d4 maximizes internal enclosure volume, ensuring that every cubic inch of your air space is working toward maximum acoustic output.\u003c\/p\u003e","brand":"Prodigy","offers":[{"title":"Default Title","offer_id":43048529035353,"sku":"NB2-8D4","price":108.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0689\/1389\/files\/prodigy-audio-8-inch-subwoofer-nb2-seriessubwooferprodigy-8812280.webp?v=1770559874"},{"product_id":"prodigy-audio-10-inch-subwoofer-nb2-series","title":"Prodigy Audio 10 inch Subwoofer | NB2 Series","description":"\u003cstyle\u003e\n  .pd-wrap { max-width: 100%; font-family: inherit; color: #cbd5e1 !important; }\n  .pd-hero { background: #0f172a !important; border: 1px solid #1e293b !important; padding: 36px 28px; border-radius: 12px; margin-bottom: 28px; border-bottom: 4px solid #06b6d4 !important; }\n  .pd-eyebrow { color: #94a3b8 !important; font-size: 13px; font-weight: 700; letter-spacing: 2px; text-transform: uppercase; margin: 0 0 10px 0; }\n  .pd-hero h2 { color: #ffffff !important; font-size: 28px; margin: 0 0 8px 0; line-height: 1.2; }\n  .pd-hero p { color: #cbd5e1 !important; font-size: 16px; margin: 0 0 18px 0; }\n  .pd-badges { display: flex; flex-wrap: wrap; gap: 8px; }\n  .pd-badge { background: #06b6d4 !important; color: #ffffff !important; font-size: 13px; font-weight: 600; padding: 6px 12px; border-radius: 4px; }\n  .pd-badge-alt { background: #1e293b !important; color: #cbd5e1 !important; border: 1px solid #334155 !important; }\n  .pd-wrap h3 { color: #ffffff !important; font-size: 22px; margin: 28px 0 12px 0; border-left: 4px solid #06b6d4 !important; padding-left: 12px; }\n  .pd-wrap p { color: #cbd5e1 !important; font-size: 16px; line-height: 1.65; margin: 0 0 14px 0; }\n  .pd-callout { background: #1e293b !important; border: 1px solid #334155 !important; border-radius: 8px; padding: 18px 20px; margin: 22px 0; }\n  .pd-callout p { color: #cbd5e1 !important; margin: 0; }\n  .pd-statgrid { display: grid; grid-template-columns: repeat(auto-fit, minmax(150px, 1fr)); gap: 12px; margin: 22px 0; }\n  .pd-stat { background: #0f172a !important; border: 1px solid #1e293b !important; border-radius: 8px; padding: 16px; text-align: center; }\n  .pd-stat .pd-statnum { color: #06b6d4 !important; font-size: 22px; font-weight: 700; display: block; }\n  .pd-stat .pd-statlabel { color: #94a3b8 !important; font-size: 12px; font-weight: 600; letter-spacing: 1px; text-transform: uppercase; display: block; margin-top: 4px; }\n  .pd-cta { background: #0f172a !important; border: 1px solid #1e293b !important; padding: 28px; border-radius: 12px; margin-top: 30px; text-align: center; border-top: 4px solid #06b6d4 !important; }\n  .pd-cta h3 { color: #ffffff !important; border-left: none !important; padding-left: 0; margin-top: 0; }\n  .pd-cta p { color: #cbd5e1 !important; }\n\u003c\/style\u003e\n\n\u003cdiv class=\"pd-wrap\"\u003e\n\n  \u003cdiv class=\"pd-hero\"\u003e\n    \u003cp class=\"pd-eyebrow\"\u003eProdigy Audio NB2 Series Subwoofers\u003c\/p\u003e\n    \u003ch2\u003eProdigy Audio NB2-10D4 10 Inch Subwoofer\u003c\/h2\u003e\n    \u003cp\u003e350 watts RMS, 14mm Xmax, double-stacked magnet, 4-layer copper voice coil on a 2-inch aluminum former, cotton-blend spider with stitched tinsel leads.

The 4-layer copper voice coil winds on a 2-inch black aluminum former. Aluminum dissipates heat faster than Nomex at the same wall thickness, which is what allows the NB2 to sustain 350 watts RMS continuously rather than in brief bursts before thermal limiting.\u003c\/p\u003e\n  \u003cp\u003eThermal management goes further with a center pole vent and radial backplate holes. The center pole vent moves heated air from behind the voice coil out through the motor while the radial backplate holes create a secondary exhaust path.

Cotton-blend spiders retain compliance more consistently over temperature cycles and have lower creep under sustained displacement, which shows up as tighter bass over time rather than progressively looser suspension as the driver accumulates hours. The tinsel leads are stitched to the spider rather than left floating. This eliminates lead slap, the audible slapping noise that loose tinsel leads produce against the cone or spider at high excursion, which is one of the most common failure points on budget drivers at volume.\u003c\/p\u003e\n\n  \u003ch3\u003ePaper Cone with Foam Surround\u003c\/h3\u003e\n  \u003cp\u003eThe NB2-10D4 uses a reinforced paper cone mated to a foam surround. Paper cones have natural internal damping that polypropylene composites lack, which gives bass a slightly warmer character. The foam surround provides higher initial compliance than rubber at the same stiffness, which contributes to the driver's ability to play low in a reasonably sized ported enclosure. Prodigy uses high-temperature adhesive and glue joints rated at 500 degrees Fahrenheit throughout the assembly to ensure the cone system stays together under sustained power.\u003c\/p\u003e\n\n  \u003ch3\u003eSealed or Ported\u003c\/h3\u003e\n  \u003cp\u003eWith a Qts of 0.514 and Fs of 34 Hz, the NB2-10D4 sits close to the boundary where either sealed or ported alignments work well. In a 0.65 cubic foot sealed enclosure the alignment approaches Butterworth, tight and accurate with F3 in the upper 40s. In a 1.0 cubic foot ported enclosure tuned to 33 Hz, output and extension both increase substantially, which is where the double-stacked motor and 14mm Xmax deliver the most impact. The enclosure performance section below shows the sealed alignment data. For the ported alignment, Prodigy Audio's published enclosure design is the starting point.\u003c\/p\u003e\n\n  \u003cdiv class=\"pd-callout\"\u003e\n    \u003cp\u003e\u003cstrong\u003eFitment at a glance:\u003c\/strong\u003e mounting depth 5.625 inches, cutout 9.25 inches, overall diameter 10.375 inches, displacement 0.11 cubic feet.
