GA-SSWX12

Subwoofer 12" / 30 cm

The GLADEN SIGMA SSWX12 is designed with one goal in mind: maximum low bass, extreme level stability, and absolute control. As the largest and most powerful model in the SIGMA series, it is ideal for installations where physical bass pressure and continuous power handling are essential. This subwoofer is built to dominate the interior, not to be restrained.

Its massive, high-performance drive with a large voice coil confidently and accurately controls the cone, even at maximum excursion. Combined with the extremely rigid and highly resilient cone, the SSWX12 delivers deep bass with enormous authority, even under sustained high-power demands. This is where it really shows its strength: uncompromising output without loss of control.

Thanks to its dual 2-ohm design, the SSWX12 can be flexibly adapted to powerful mono and multi-channel amplifiers. It is optimized for closed and bass reflex enclosures, forming the perfect basis for high-power, uncompromising car audio systems.
