Prodigy Audio 8 inch Subwoofer | NB2 Series

Versatile High-Excursion Performance

The Prodigy Audio NB2-8d4 is a precision-engineered 8-inch subwoofer designed to bridge the gap between space-saving integration and high-output performance. 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.

Thermal Management and Motor Integrity

Reliability 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.

Integration-Focused Footprint

Designed 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.
