Notice On Packaging For Subwoofers
Sundown Audio has led the industry in quality and performance for over a decade. To improve accuracy and transparency, we have updated our subwoofer power ratings to reflect true real-world performance.
During this transition, some packaging may show previous ratings. Performance fully aligns with our current published specifications. If you have any questions about authenticity or ratings, please contact directly for confirmation.
The X-6.5SW is Sundown Audio's first true sub-woofer smaller than 8 inches in diameter. It features a voice coil identical in winding dimensions to their SA-8 v.3 subwoofer (a massive 2” diameter coil with a 1.4” winding height) so thermal power handling is absolutely massive.
Specifications:
  • Xmax: 16mm one-way by 70% BL
  • Large noise-free pole vent design
  • Specially designed spiral-cut basket venting technique (unique to this model in our line)
  • 2” diameter 4-Layer CCAW wire voice coil wound on thick Kapton former
  • Copper Pole-Cap For Reduced Inductive Distortion
  • Integrated Tinsel Leads to prevent lead slapping
  • Proprietary flat aluminum diaphragm
  • Note on Power Handling: This woofer is mechanically limited. It requires a SMALL ported enclosure. Placing it in a large or sealed enclosure will reduce mechanical power handling substantially.
    • Ported: 0.25-0.33 ft^3 volume
