Gladen Sigma SSWX065-Dual

The Gladen Sigma SSWX065-Dual combines two powerful 16.5 cm (6.5-inch) subwoofers from the SIGMA Extreme series in a precisely tuned bass-reflex enclosure. With a power handling capacity of 400 watts RMS and 800 watts peak, this compact dual-subwoofer system delivers powerful, dynamic bass reproduction while maintaining high precision and control.

The two long-throw SSWX drivers feature a powerful, FEM-optimized drive system, sturdy aluminum baskets, and exceptionally rigid fiberglass cones. This design allows for a large excursion and ensures controlled reproduction with powerful, precise transients, even during demanding bass passages.

The dual-driver configuration provides a larger cone area, enabling the subwoofer to produce an impressive low-frequency foundation. The specially tuned bass-reflex enclosure supports a powerful bass performance and allows for integration into high-performance car audio systems without taking up too much space in the vehicle.
