'At their price, plus the cost of the crossover and a driving amplifier, the Thor’s Hammer can hardly be described as cost-effective—until you’ve lived with it. Then it starts to make a horribly compelling sort of sense, especially in the context of a system that already contains amplification and speakers that have breached the five-figure price barrier. I’m fortunate enough to breathe a heady and rarefied audio oxygen, one in which frighteningly expensive components come and go on an almost daily basis. But since living with first the WATCH Dogs and now the Hammers, there really is no going back. Bandwidth, real bandwidth, has an addictive quality, an ability to satisfy and convince that underpins the very promise and proposition of high-end audio.“

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.?

Drivers
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.
