Sundown Audio 12" 750 Watts RMS DVC Dual 4-Ohm Car Subwoofer — Black

Powerful 12-inch car subwoofer from Sundown Audio engineered for deep, controlled bass with a 750 Watts RMS rating. The dual 4-ohm voice coil (DVC) design provides multiple wiring options for system flexibility. Built components and cooling features deliver reliable performance and reduced distortion under heavy use. Key features include a 19mm one-way Xmax at 70% BL, a vented magnetic gap for better cooling, and an optimized high-velocity pole vent to minimize distortion and improve clarity. Airflow is further enhanced by a high-velocity vented frame spacer ring. Thermal and mechanical durability are addressed with a black aluminum 2.5" voice coil former, high-temperature copper voice coil wire, and a large aluminum Faraday ring to improve magnetic performance. The speaker uses stitched-on "XL" tinsel leads to prevent fatigue, spring-loaded terminals for secure connections, and a high-strength cast aluminum frame for structural rigidity. These design choices combine into an optimized coil ventilation system. This woofer is tuned for use in small ported, sealed, or bandpass enclosures to achieve the best results.
