Sundown Audio ZV6-12 D1 12 in 3250W RMS DVC 1-Ohm Car Subwoofer, 35mm Xmax, Vented Frame, for Ported Boxes, Pair

Product Overview: The Sundown Audio ZV6-12 D1 pair includes two 12 inch car audio subwoofers built for high output bass systems that need serious power handling and extended cone travel. Each subwoofer is rated at 3250 watts RMS and 6500 watts peak, with a dual 1-ohm voice coil design for flexible system wiring. This 2-piece multipack is suited for custom car audio builds where matching drivers are needed for balanced output.
Performance Focus: Each ZV6-12 D1 uses a quad stacked 240mm motor structure with a 100mm magnet stack height, a hyper extended pole, and added mechanical clearance for high excursion playback. With 35mm one way Xmax, a BL rating of 20.792, and sensitivity of 83.7396 dB at 1 watt and 1 meter, the subwoofer is designed to deliver low frequency output with control when paired with the proper enclosure and amplifier setup.
System Use: This pair is intended for experienced car audio installers building a powerful ported subwoofer system. The recommended ported enclosure size is 2.5 cubic feet per subwoofer with 38 square inches of port area and tuning around 32 Hz. Sealed enclosures are not recommended for this model. A 4th order design can also be used with a 1.0 cubic foot sealed side and 3.0 cubic foot ported side.
Design Details: The ZV6-12 D1 features a black aluminum 3 inch 8-layer flat wire voice coil, spring loaded terminals, stitched-on XL tinsel leads, a large aluminum Faraday ring, and a custom tooled basket. Venting is built into multiple areas of the assembly, including the pole vent, magnetic gap, cast aluminum spacer ring, and machined channels around the pole piece for airflow support.
Reliability Built In: Sundown designed the Z v.6 platform for demanding low frequency use in small ported box applications while maintaining stable suspension behavior. The Mega-Roll v.2 surround, ultra-linear spider packs, heavy motor structure, and aluminum voice coil former work together to support durability, thermal control, and consistent performance when installed within the recommended specifications.
