Wilson’s Mk.2 Sasha
The revision of the Sasha to Mark II status involves a number of improvements, the cumulative effect of which, according to Peter McGrath, is quite significant. The Sasha II has the same midrange and woofer as the original Sasha, but the tweeter is all newa convex rather than a concave dome as used previously. The tweeter and midrange baffle materials are different from those in the original Sasha, and the effect is a 34% reduction in resonant modes. The mechanism allowing the mid/tweeter module to be tilted, to "focus" the sound, has been revised so that the focusing can be more precise.
