This Listing Includes: (1) Sundown Audio X-Series v.3 8″ X-8 Subwoofer
The Sundown X-8 v.3 is one of the most popular 8″ subwoofers Sundown has ever produced, building on the v1 and v2 and improving on both. The key is its FEA-optimized spider and surround, paired with the custom-tooled 8″ frame that represents the maximum performance possible on that platform. The motor and coil deliver roughly 19mm of one-way linear Xmax — about 2.4″ peak-to-peak before the coil leaves the gap — and an aluminum magnet-ID shorting ring reduces inductive distortion. The 800-watt RMS rating is quite conservative. Available in D2 and D4, it’s right at home in small sealed or ported enclosures. Authorized Sundown Audio dealer at JS Ultimate Sounds. Free shipping on orders $99+.
