The Sundown Audio SA-12 D4 Classic set includes two 12 inch car subwoofers, model SW-SACL12D4, built on the SA Classic platform. Each subwoofer is rated at 1000 watts RMS and 2000 watts peak. Each has a dual 4-ohm voice coil for flexible wiring.
Each driver has a custom 2.5 inch voice coil with high-temperature voice coil wire and a low distortion motor. A large aluminum Faraday ring helps smooth the acoustic response. The 19 mm Xmax gives the cone room to move.
The frame is high strength cast aluminum. The cone is competition-grade paper with a foam surround and a double-layer Nomex spider. Stitched-on XL tinsel lead wires and spring-loaded terminals connect the driver to the system.
