density and truthfulness, and dynamic clarity to appreciate the resulting vast improvement
in the midrange over other designs.
The original version of Wilson Audio's Convergent Synergy tweeter was developed in
conjunction with the Alexandria XLF. It now makes its debut in a new custom form, spe-
cifically designed to meet the needs of the Mezzo Convergent Synergy's mission. During
the development of the Convergent Synergy tweeter, Dave and the engineers tested a wide
spectrum of tweeters fabricated with exotic materials such as diamond and beryllium. Each
have their own unique qualities and virtues. Many exhibit flat frequency response, or are
extended several octaves above the audible bandwidth. But none matched the dynamic
contrast and harmonic expression of Wilson's existing titanium design. But most impor-
tantly, none of them were an ideal match to our midrange driver. The Convergent Synergy
tweeter rejects exotic materials in favor of a uniquely constructed silk dome design. With
the Convergent Synergy driver, the design requirement of ultra-low distortion and very
robust power handling down in the lower part of its range are beautifully met. These quali-
ties converge with a much higher resonant frequency and flat ter frequency response when
compared to the original inverted titanium design. Wilson's Convergent Synergy tweeter
is extremely linear. It crosses over synergistically to Wilson's midrange driver. The noise
floor is much lower than the titanium driver it replaces. The Mezzo Convergent Synergy
crossover features technology that accounts for the formidable performance envelope of-
fered by the Convergent Synergy tweeter.
The Convergent Synergy tweeter's acoustic and mechanical demands are somewhat
dif ferent from the titanium tweeter it replaces. Using the latest version of Wilson's propri-
etary composite, X-material, Wilson's engineers designed an all new tweeter module. The
module is extremely inert and non-resonant. It also accounts for the Convergent Synergy
tweeter's dispersion characteristics. Great care was taken to address dif fraction—a type of
time-domain distortion that results from reflections of f the speaker cabinet. The shape of

the module is emblematic of this effort, as is the shape and material of the energy-absorbing pad
that surrounds the tweeter.
Sasha W/P Series 2 woofer. The Mezzo Convergent Synergy sources its woofer di-
rectly from the Sasha W/P Series 2. The speed, dynamic alacrity, and tunefulness that are
all distinctive features of the latest Sasha are in evidence here in similar proportions.
In the main module, Mezzo Convergent Synergy's two woofers are mounted horizon-
tally, flanking the midrange driver. Achieving near perfect driver-alignment at the listening
position requires the adjustability of the tweeter by changing its relative position in rela-
tion to the midrange and woofer drivers, such that all drivers' acoustic centers are equidis-
tant from the listener. The tweeter module is adjustable via a provided chart according to
ear height and listening distance —and for a variety of Mezzo Convergent Synergy instal-
lation strategies. Whether the Mezzo Convergent Synergy is installed directly on the floor,
on one-of-two custom designed stands, or in custom cabinets, the Mezzo Convergent Syn-
ergy's drivers can be properly aligned to accommodate these scenarios.
Just as in the Sasha, the Mezzo Convergent Synergy uses an "S" Material midrange
baf fle. S -material is a relatively new enclosure composite designed in conjunction with the
Sasha W/P. The S -material baf fle reduces measurable and audible noise and coloration in
the critical midrange. Wilson's proprietary X-material is used in the balance of the enclo-
sure walls, continuing Wilson's practice of building ultra-low resonance cabinets.
Two stands: The Hourglass Stand features a solid front plinth, which allows for 2π Ste-
radian support of the midrange and woofer drivers, resulting in more linear and impact ful
performance in the upper bass and lower midrange. The second optional stand features an
pedestal, which can be customized for overall height; the Mezzo can be optimized for the
specifics of center channel placement in relationship to large cinema screens.
