Section 1—Introduction

Section 1.1—Mezzo Introduction

From all of us at Wilson Audio Specialties—thank you for purchasing the Mezzo loud-

speaker. The information contained within the pages of this manual will inform and instruct

on the proper assembly, set up, and long term care of your Mezzo.

The Mezzo was formulated and engineered with a specific function in mind: a loud-

speaker endowed with similar authority and dynamic range as Wilson’s Sasha W/P, MAXX®,

and even the Alexandria® X-2. When used as a center channel, Mezzo seamlessly matches

the acoustic signature of Wilson’s larger loudspeakers – whether the main left/right speak-

ers are Sashas, MAXXs, or two more Mezzos. The Mezzo also provides an unprecedented

level of musical accuracy in music systems and home theaters where its low-profile form

solves architectural challenges, such as in those installations where a tall loudspeaker

would block the view afforded by large windows, or would obstruct wall-hanging artwork.

Whether it is used as a center channel or as a main loudspeaker, Mezzo matches the tonal

beauty, dynamic speed, tonal sophistication, resolution, and sense of “thereness” of its

taller Wilson brethren.

but in a low-profile package. When used as a center channel, Mezzo seamlessly matches

the acoustic signature of Wilson’s vaunted Sasha. Indeed, the Mezzo features a driver

complement identical to the Sasha, with the exception of the midrange driver, which is

borrowed from the legendary Alexandria X-2

dented level of musical accuracy in music systems and home theaters where its low-profile

form solves architectural challenges, such as in those installations where a tall loudspeaker

would block wall-too-wall cinema screens, the view afforded by large windows, or would

obstruct wall-hanging artwork. Whether it is used as a center channel in conjunction with

Sasha, MAXX, or Alexandria, or as a main loudspeaker, Mezzo matches the tonal beauty,

dynamic speed, tonal sophistication, resolution, and sense of “thereness” that are hall-

marks of Sasha W/P.

Among the technical innovations of the Mezzo:

• The Mezzo sources its midrange driver directly from the ground-breaking

Wilson Alexandria Series-2. With this midrange driver, Dave and the Wil-

son engineers set out to redefine what was possible in cone midrange

technology—and to capture certain qualities of live music heretofore not

achieved in any other design. Their efforts were rewarded. The result was

the Wilson midrange driver. One has to hear the clarity, tonal density and

truthfulness, and dynamic clarity to appreciate the resulting vast improve-

ment in midrange over other designs.

• The tweeter, sourced directly from the Sasha W/P, uses advanced technol-

ogy and material in the area behind the diaphragm. All tweeter diaphragms

are partially acoustically transparent. Any out phase or time-delayed re-

flections that make their way out of the front of the diaphragm is heard and

measured as noise and distortion. The Mezzo tweeter employs proprietary

materials in combination with proven mechanical configurations that ef-

fectively reduce these time-delayed reflections behind the inverted dome,

preventing them from subsequently corrupting the primary wave. As with

Sasha, the Mezzo tweeter excels in all areas of high-frequency perfor-

mance: clarity, dynamic expression, sweetness of tone, and resolution. It

is an excellent companion for the proprietary Wilson midrange driver. The

resulting fabric of tonal beauty woven by these two drivers is both seam-

less and complete—richly portraying instruments as they are heard in life.

• Sasha W/P woofer. The Mezzo sources its woofer directly from the Sasha

W/P. The speed, dynamic alacrity, and tunefulness that are all distinctive

features of the Sasha are in evidence here in similar proportions.

• Adjustable tweeter module design and array geometry designed to address

the challenges of a low-profile loudspeaker. In the main module, Mez-

zo’s two woofers are mounted horizontally, 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 relation

to the midrange and woofer drivers, such that all drivers’ acoustic centers

are equidistant 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 installation strategies. Whether the Mezzo is installed

directly on the floor, on one-of-two custom designed stands, or in custom

cabinets, the Mezzo’s drivers can be properly aligned to accommodate

these scenarios.

• Crossovers. The Mezzo crossover features technology adapted from the

Sasha W/P as well as the Series 2 Alexandria, and the MAXX Series 3. The

goal was to reduce propagation-delay jitter and to lower the noise floor.

Mezzo’s overall resolution, intertransient silence, dynamic speed and nu-

ance are nearly identical to the Sasha W/P.

• “S” Material midrange baffle. S-material is a relatively new enclosure com-

posite designed in conjunction with the Sasha W/P project. The S-material

baffle reduces measurable and audible noise and coloration in the critical

midrange. Wilson’s proprietary X-material is used in the balance of the en-

closure 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 Steradian support of the midrange and woofer drivers, resulting in

more linear and impactors performance in the upper bass and lower mid-

range. The second optional stand features an adjustable pedestal ideal

for customizing center channel placement in relationship to large cinema

screens.

More on Propagation delay

A musical waveform is a complex overlay of frequencies, amplitudes, and phase

relationships. With current technology, no single transducer can reproduce the full range

solution is the multiple driver array, with specific drivers dedicated to various portions

of the frequency range. Multiple drivers introduce their own set of problems. A challenge

typically ignored by speaker designers is preserving the precise time relationships of the

leading edge of the musical waveform.

The key to solving this problem lies in Wilson’s innovative and patented Adjustable

Propagation Delay technology, which employs movable modules that allow the individual

adjustment of the drivers in the time domain. Using this technology, each driver’s wave-

form propagation “matches up” with the other drivers in the system in such a way as to

create the sonic equivalent of a single point source. There are certain loudspeaker makers

other than Wilson that recognize the need to correctly align their drivers, but they do so

for only one theoretical listening position.

The fact is, misalignment of the drivers by fractions of an inch will audibly degrade

transient accuracy, soundstage height, depth, and width. Misalignment of the drivers will

also introduce tonal anomalies that destroy the otherwise convincing “presence” of an in-

strument or a singer’s voice. Wilson’s solution for propagation delay correction has long

set the standard for precise driver positioning in order to insure correct time-alignment for

a wide range of real room listening distances and ear heights.

The Mezzo cabinet is a further evolution of Wilson’s philosophy that truly great

forms follow a corresponding function. It is a visual metaphor for the solution Wilson Au-

dio pioneered to address issues of phase coherence exacerbated by large speaker systems.

Typical of the creative process, the solution itself is an analogy to the field of optics and

the design of wide-angle lenses. The means of maintaining edge-to-edge sharpness at both

close and far focusing distances for a high quality wide-angle lens suggested a solution to

the similar problem of time domain accuracy for large speaker systems at both near and far

listening positions.

With Mezzo, Wilson Audio takes this concept a logical step further, addressing the

issue of optimal driver dispersion in the large cabinet system. Ideal driver dispersion for

both near and far listening positions requires the drivers be adjustable not only forward

and back, but also able to rotate on their vertical polar axes.

Section 2—Uncrating your Mezzo

Section 2.1—Uncrating the Mezzo

Initial Check

The Mezzo is shipped in a wooden crate. Upon receiving your Mezzo, please check

the crate’s condition. If the crate is damaged, please report it to the shipping company im-

mediately for insurance verification.

The following items are recommended for this procedure:

• Electric Screwdriver

• Phillips head drive bit

• Masking tape (for use in speaker setup)

Uncrating the Mezzo

A minimum of two strong adults is required to set up the Mezzo.

1. With the crate lid facing up, unscrew the wood screws securing the lid. Re-

move the lid.

2. One crate will contain the tool kit.

3. The Mezzo is shipped with casters installed. Carefully lift the crate upright

so that the Mezzo is now vertical. With the Mezzo’s bottom toward the floor

and one person holding the crate, the second person should reach in and

gently roll the Mezzo out of the crate, carefully, so as not to hit the Mezzo

on the crate and scratch the paint.

Section 2.2—Crate Content Checklist

Now that you have unpacked your Mezzo, you can inventory all the additional items

in the crate.
