Unmatched Performance and Durability

Its 2.75” aluminum voice coil former is designed for superior heat dissipation, outperforming most 3” coils without adding unnecessary mass. This subwoofer’s motor is equipped with a large aluminum Faraday ring, which reduces distortion and ensures smooth acoustic response across the entire frequency range. Paired with a competition-grade paper cone and a strong foam surround, this subwoofer is built to withstand the rigors of high-performance audio environments.

Advanced Cooling and Ventilation

Sundown Audio has incorporated innovative cooling technologies to keep the SAv2 18" D2 Subwoofer performing at its best, even during extended use. The vented magnetic gap and high-velocity vented frame spacer ring work together to maintain optimal operating temperatures, while the spring-loaded terminals and stitched-on double “XL” tinsel lead wires ensure reliable connections and long-lasting durability.

Superior Acoustic Design

The SAv2 18" D2 Subwoofer features a patented high-strength cast aluminum frame, providing a solid foundation for the powerful motor and coil setup. The motor’s large magnet shorting ring (Faraday ring) reduces inductive distortion, delivering a smoother and more natural sound. With over 35mm of mechanical excursion, this subwoofer can produce deep, resonant bass that adds depth and richness to any audio setup.
