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.

“That’s the new tweeter” one said in hushed tones. “Wow” said the other, suddenly unable to form even a sentence in the presence the gleaming black transducers.

“See” said Peter McGrath, Wilson Audio Specialties sales director, standing with me a few feet away. “Everybody notices the new tweeter. What they are not talking about is this.”

He rapped his knuckles on the side of the lower woofer module. There was barely a thud.

“Dave Wilson invested in a device called a vibrometer. It uses a laser to detect all the resonant modes in the cabinet. We used it in the development of the Sasha II.”

Considering that Wilson Audio has for years gone to extraordinary lengths to make its cabinets as acoustically dead as possible – even developing its own proprietary “X” and “S” materials rather than relying on plywood – this was something of a surprise. I’ll bet Dave hunts squirrels with an elephant gun, too.

The X and S materials are so hard already that they reportedly wear out cutting blades in no time. But Wilson engineers used the vibrometer to improve the cabinet design and bracing to reduce what little resonances there were by 34 percent, McGrath said.

“Here’s something else we did,” he continued, walking around to the back of the speaker and slightly lifting the rear edge of what used to be called the “Watt” portion, the physically separate enclosure that holds the midrange and tweeter. Read More
