SA-Series v.3 8-Inch Subwoofer

The Sundown Audio SA-Series v.3 8-inch subwoofer is engineered to deliver exceptional bass performance in ported enclosures, emphasizing low distortion. It features a robust build with a patented high-strength cast aluminum frame and a vented magnetic gap equipped with 16 chamfered vents designed to maintain high-velocity airflow over the voice coil for improved thermal performance. This model boasts 600 Watts RMS and 1200 Watts Peak power handling capabilities, with dual 2 or 4 ohm voice coils available. It incorporates a large aluminum Faraday ring to ensure a smooth acoustic response and utilizes high-temperature voice coil wire along with stitched-on “XL” tinsel lead wires for enhanced durability. The subwoofer is built for longevity, featuring a full 16mm of one-way linear excursion and mechanical capacity that more than doubles its linear limits, contributing to both its robustness and low distortion characteristics. The v.3 update introduces a new surround with optimized linear geometry. The product specifications include an impedance of D2 (Dual 2-Ohm), an RMS Power of 600W, and a Peak Power of 1200W.
