Overview
The GLADEN SIGMA SSW065 was specially developed for compact vehicle installations requiring controlled bass and high precision. Despite its small size, this 6.5-inch subwoofer delivers powerful performance thanks to its long-stroke suspension unit. These features ensure clean bass impulses and high control.
The FEM-optimized motor structure provides efficient power transmission with low distortion. Combined with the lightweight yet stable paper cone and precisely tuned suspension, the SSW065 delivers an accurate, dry low-frequency response, making it ideal for closed and compact bass reflex enclosures.
Thanks to its dual 2-ohm voice coil, the SIGMA SSW065 offers maximum flexibility in system integration and is ideal for modern, space-saving vehicle concepts that require high sound quality.
- Compact 6.5″ subwoofer for precise bass.
