Because the WATT Puppy is the best selling over-$10,000 loudspeaker in history, one might expect Wilson Audio to leave well enough alone. But that would overlook Wilson's commitment to define for the industry the bounds of the possible in speaker design.

Wilson's unique materials research has led to the first new WATT cabinet in its 17-year history. For the first time, the Puppy has a new driver.

And to better integrate the two, countless hours were spent refining the crossover. The changes appear subtle; the difference they make is not. In terms of resolution, coherence, bass speed and impact, an already great loudspeaker has been raised to an astonishing new level. Finally, new styling cues join the WATT and Puppy more beautifully than ever.

It was a painstaking process, but at the end of the day we had to be able to say one thing with confidence: This is the best WATT/Puppy the world has ever known.
