X-Series v.2 6.5" Subwoofer
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
-
RMS Power: 400-watts
- 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.

Box Recommendations:
- Sealed: .15 ft^3
- Ported: 0.3 ft^3
