The original Puppy high speed woofer was introduced in 1988, two years after
the first WATT, series I. Prior to the Puppy, users of the WATT who desired more low
frequency extension, would add various subwoofers from other manufacturers. The
results were unpredictable and often compromised overall musical performance. It be-
came clear to Mr. Wilson that none of these subwoofers provided the speed necessary to
blend seamlessly with the lightning-quick WATT.
Thus, in the initial design phase of the Puppy, Wilson concluded that what was
needed was a highly articulate, low distortion, non-resonant, compact high-speed woofer
with robust power handling, high sensitivity and excellent reliability. In every 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.
The crossover network in the base of the Puppy is always composed of the finest audio
grade components, held to tolerances better than 0.1%.

The System 7 Puppy employs a new woofer driver. Bass performance,
especially in the areas of transient speed and frequency linearity, is notably im-
proved over any previous generation Puppy. Bass extension into the bottom
octave is also slightly enhanced. The Puppy 7’s bass performance is more con-
sistent in a wider variety of rooms and environments.
