Wilson Audio has a long history of utilizing technology pioneered in previous projects. In many ways, each new Wilson product is but the latest receptacle for its cumulative scientific research. With Sasha Series-2, precise time alignment, so critical to harmonic expression, dynamic alacrity, and musicality, has reached an unprecedented degree of refinement for a two cabinet loudspeaker. And the Wilson Convergent Synergy Tweeter, which transformed the sound of the Alexandria XLF, has now been modified for Sasha’s two cabinet configuration.
Sasha, like the WATT/Puppy before it, remains Wilson’s best selling speaker. Its combination of high performance in a relatively compact form factor has always been its greatest strength, and now the performance side of that equation has risen to an entirely new plane.
All four drivers in the three-way Sasha W/P are proprietary Wilson designs; each has been either upgraded from its own predecessor or brought in from the next most expensive model in the Wilson line. Among the latter is the Sasha's 1" inverted titanium-dome tweeter, sourced from Focal and developed for the Maxx Series 3, and described as the fruit of Wilson's best efforts to prevent rear-firing energy from creating high-frequency distortion. The tweeter's second-order high-pass filter is tailored to approximately 1.8kHz, below which Wilson's 7" midrange driver, also developed for the MAXX 3, takes over. David Wilson says that the pulp-composite driver could actually extend as far as 11kHz without the crossover—"The way we're using it, it's kind of loafing"—and he stresses the need for a good midrange driver to accommodate very different demands: "In the bass, performance tends to cooperate more with the math and science. But there's a bit more art to the midrange, where you need both high excursion and great subtlety of detail."
The second-order high-pass filter for the midrange driver is set at about 150Hz, which is also the frequency for the woofers' first-order low-pass filter. The woofers, made for Wilson by ScanSpeak, are based on the 8" polymer-cone woofers from the WATT/Puppy 8. But for the Sasha W/P they've doubled up on the magnets, which reportedly yields better acceleration and electrodynamic damping.
