Prodigy Audio NB5 12" D4 Subwoofer | 1200W RMS

Prodigy Audio NB5 12" Subwoofer | 1200W RMS – High-Power Bass for Daily & SPL Builds

Engineered to Deliver. Built to Dominate.
The Prodigy Audio NB5 12" Subwoofer is a heavy-duty bass machine built to push limits. With a beefy 1200 watts RMS power rating, 27mm of one-way Xmax at 70% BL, and a high-temp 2.75" flat aluminum voice coil, this sub is built for deep, distortion-free lows that hit hard and stay clean—whether you're cruising daily or competing in SPL.

Its vented 280oz ferrite motor is optimized with upper and lower Faraday rings, drastically reducing distortion from inductance across the entire excursion range. The black aluminum voice coil is mated to a high-mass cast aluminum frame that not only supports the structure but acts as a built-in heat sink for thermal regulation during extended use.

A treated paper cone, double-stitched tinsel leads, extreme-duty Nomex spider, and heavy foam surround round out this competition-grade woofer, making it a perfect balance of performance, durability, and output.
