The Laws of Physics at 10Hz

The Thor’s Hammer is the lineal descendant of all these subwoofers. But most significantly, it’s the first subwoofer that utilizes the new driver and crossover technology developed for the WATCH Dog® to equal and surpass the performance of the XS in a cabinet that won’t overwhelm most rooms. The result is flat bass extension below the limit of human hearing—into the frequency range where the word “visceral” becomes literally descriptive.

Long-throw woofers allow Thor’s Hammer to achieve its 10hz response in a relatively compact enclosure. 


Thor’s Hammer uses two custom-designed 15” dual-spider drivers in a dual-ported cabinet. The resulting distortion measurements are of the order one associates more with the finest quality amplifiers rather than with loudspeakers!

Enclosure Materials

The cabinet itself is constructed primarily from Wilson Audio’s proprietary X-Material, an extremely dense and hard composite that achieves the seemingly contradictory attributes of high rigidity and high damping. Reducing cabinet resonance to irrelevancy is the sine qua non of accurate and grain-free music reproduction.

Home Theater/Music System Integration

The benchmark in designing Thor’s Hammer was simple: create a subwoofer that would be, in every measure, a worthy addition to a music system built around Wilson’s flagship loudspeakers.
