DS18 ZXI8.4D 8" High Excursion Subwoofer – 1200W Max, Dual 4-Ohm

The DS18 ZXI8.4D is a monster 8-inch high-excursion subwoofer engineered for bassheads who demand serious low-end authority but are working with tighter installation spaces. Designed to completely dominate the compact subwoofer category, the ZXI series bridges the gap between heavy-hitting SPL performance and premium sound quality. It is built around a highly efficient 2-inch high-temperature black aluminum voice coil that absorbs and dissipates heat flawlessly. This allows the subwoofer to handle a massive 600 Watts RMS (1200 Watts Peak) without breaking a sweat, guaranteeing crisp, distortion-free bass during extended, high-volume jam sessions.

To generate competition-level air movement from an 8-inch cone area, the ZXI8.4D is equipped with an oversized 104-ounce quad-stacked ferrite magnet motor structure. This immense magnetic force provides absolute control over the rugged non-pressed paper cone, which is tethered to a thick, high-excursion foam surround. This combination ensures maximal one-way linear travel (Xmax) to physically punch the air and deliver true, physical bass response down to 25Hz. Housed in a rock-solid, custom sandblasted black aluminum basket, the DS18 ZXI8.4D provides relentless, high-fidelity bass for custom trucks, under-seat enclosures, and daily drivers. With its Dual 4-Ohm configuration, it offers the perfect wiring flexibility for multi-sub builds, easily dropping a pair down to a 1-Ohm final load.
