WATCH Center series 3 The WATCH Center Series 3 sources its tweeter from the Sasha W/P and Sophia Series 3. This proven design is slightly more efficient than the tweeter it replaces. It is also more expressive of both large and small scale dynamics. Most importantly, it is better suited and matched to the Wilson midrange driver. The acclaimed Wilson midrange was developed originally for the Alexandria Series 2 by Dave Wilson and his team of engineers. The Wilson mid was born of countless hours of listening to live, unamplified music in the great concert halls of the world, most notably the Musikverein in Vienna. Design goals were natural timbre, dynamic alacrity, and high-resolution. Dave was particularly concerned with resolving the very early reflections he heard when listening to live music, but which where missing in all previous loudspeaker designs in his experience. In order to resolve this subtle transient information, Dave knew the new driver must exhibit very fast and controlled settling time.the behavior of the driver's cone just after an initial transient. To capitalize on the performance advantages of the Wilson midrange driver, a complete redesign of the crossover was in order for WATCH Center 3. Along with the latest in Wilson's unique anti-jitter technology, which accounts for interactions between high- and low-pass filters, special attention was given to the crossover's signal path and component layout, with measurable reductions in component interaction. The new crossover allows the Wilson mid to "speak" articulately from a near-silent background. Like the new Surround speaker, the second generation WATCH Center channel benefits from a significant (30%) increase in enclosure volume without an increase in cabinet size. This naturally translates into deeper bass extension, but the real magic happens in the midrange, where a center channel speaker does most of its work. Utilizing two of the midrange/woofer drivers from Sophia, the Wilson Center channel now boasts the same midrange dynamic speed and punch as the MAXX Series 2. Tweeter The Center Channel's tweeter is the same driver used in WATT/Puppy System 8 and the MAXX Series 2. The adjustable tweeter module facilitates precise phase alignment between the Center channel and the front stereo speakers, creating a completely coherent and three-dimensional sound field. Crossover Once again, the anti-jitter crossover technology derived from the large Wilson loudspeakers brings the same grain-free transparency to the Center channel. Dialogue emerges from a truly black background with unprecedented clarity and dimensionality.
