The Original Puppy high speed woofer was introduced as a solution to solve the unpredictable results of pairing the WATT with other commercial subwoofers for those who wanted lower frequency extension.

In the initial design phase of the Puppy, Wilson concluded that what was needed was a higly articulate, low distortion, non-resonant, compact high-speed subwoofer with robust power handling, high sensitivity and excellent reliability. In ever series of puppy, two very high quality low-frequency drivers are driven in parallel in a rigidly cross-braced, tuned enclosure to quickly dampen spurious resonances in the structure.
