Unpacking and set up
instruction
Important Points before Setting
up
During installation two or more people will e
required, as the speakers are quite heavy.
Never attempt to unpack or install the
speakers without assistance as this could
result in damage to the speaker or
personal injury. Please o serve normal
procedures for lifting and correct posture
when handling the speakers. Soft fa ric
gloves are recommended to prevent damage
to the high quality finish. Also, it is strongly
recommended that all watches and jewellery
e removed prior to unpacking.
Patient and careful setting is essential to
o taining the maximum performance from
this system.
• Move the speaker, within its packaging, to
the intended listening position. For
further information on positioning, see
the Loudspeaker Positioning section
elow.
• Making sure the top of the ox has een
fully opened and the hardware pack has
een removed.
• The speaker is now ready to e removed
from the ox. Have an assistant help you
lift the speaker clear of all the packaging.
Stand the speaker on the floor, taking care
not to damage the foot. The protective
polythene ag can e slippery, so great
care must e taken at this stage.
• Once oth speakers have een stood up,
the ags can e removed and the
packaging stored for future use, as it is
essential for shipping the system safely.

The subject of room
acoustics
Acoustics is a complex su ject and this text
should e treated for what it is, a simple ut
for some, informative guide. For a more in-
depth understanding you would need to refer
to a whole range of texts on the su ject. The
most important outcome of this should e the
greater appreciation of the role, played y the
room on the overall sound of the audio
system.

3
The air contained within the room is the link
etween the output of the loudspeaker and
your ear. How air ehaves is dependent upon
the attri utes or character of the room. It
follows that a etter understanding of asic
acoustics and what facets cause the most
influence in the room will assist in making
decisions a out the way in which the room
and su sequently the system can e improved.
Room types fall etween two extremes. A
room can e “dead” on the one hand (full of
highly energy a sor ent materials and
complex diffusing structures) or very “livel ”
on the other (few reflective surfaces and a
high proportion of very reflective, hard, non
a sor ent surfaces). As so often is the case, a
alance of materials is commonly prefera le
to one extreme or the other. The correct
alance is the goal for the end user.
Room attributes which can be
easil changed
The contents of the room impact greatly upon
its overall acoustic character. As you would
expect, hard surfaces like glass and concrete
tend to reflect a road and of acoustic
energy. Complimentary materials that are soft
and thick in section such as heavy natural
fi re curtains will tend to a sor a road and
of frequencies.
What are Standing waves?
Sound waves reflecting etween two parallel
walls set up resonance modes when one half,
or a whole multiple of one-half, the
wavelength of the sound wave is equal to
the distance between the walls.
These resonance modes are referred to as
“standing waves”. In loudspeakers with
parallel walls these waves will cause
distortions. The standing waves in your room
will distort the frequency response of your
system sympathetically oosting certain
frequencies.
If a certain standing wave frequency is
acoustically isolated from its modal
neigh ours, its effect is more likely to e
audi le and pro lematic. This can
compromise the accuracy of any loudspeaker.
Middle and High Frequenc
Room Characteristics
The middle and high frequencies are affected
more y room contents rather than room
shape. The surfaces and how they reflect,
a sor or diffuse the acoustic energy will tend
to descri e the “sound” of a room. Like all
energy, acoustic energy cannot e destroyed; it
can only e converted into something else or
reflected. The shape of the surface will
determine how it is reflected and the material
will determine whether it is a sor ed. All
rooms have a particular sound, and to
appreciate what influences are present in your
room you should e aware of how the o jects
in your room will respond to sound.
Sound waves ehave in the same way as light
waves or "rays" and so imagine the driver to
e a floodlight.
Reflection: acoustic energy is not converted
ut reflected in an orderly, predicta le
fashion.
Diffusion: acoustic energy is dispersed in a
random and or disordered fashion.
Absorption: acoustic energy is converted
into kinetic energy or heat. All or a majority of
the sound energy is "soaked up" or disposed
of y the o ject surface or room oundary.
Bi / Tri Amping
The power that is delivered to your
loudspeakers will have a direct effect upon the
sound of your loudspeakers. You should
select the est that you can afford. Separating
the systems will deliver enefits that can easily
e detected. We would not recommend using
different amplifiers on different drivers.
Bi / Tri Wiring
Improvements can e heard through
separating the energy from each filter in the
crossover. Ca les vary in construction ut a
good quality ca le should e low in
impedance, inductance and capacitance. Do
not use ca les, which act as additional
crossover components. Experimentation is
crucial in this situation and a ca le that works
well in one situation / room / with a given
amplifier, may not always perform as well
when one of these varia les are changed.

Two channel loudspeaker
positioning
There are no o jective criteria that can e
used to state precisely where loudspeakers
should e positioned. Should any individual or
company suggest that there is, they should e
regarded as special people and treated with a
great deal of caution. In the glo al scenario,
our loudspeakers are driven y unique systems
that are selected y the owner ecause of
particular virtues. Every listening room is as
individual and unique in character as the
owner. Compound this complex picture with
the com ination of different equipment.
Consider the changea ility of rooms, if the
room is dressed with heavy curtains simply
changing the curtains position can alter the
whole alance of the system. The only rule is
that there are no rules. Like producing good
wine, it is the goal that is the only guide. The
owner is the pivot in this su tle alancing act.
The goal of high performance audio systems
is accurate reproduction. The information, e
it in groove or pit format should e
transcri ed, amplified and converted ack into
sound energy without the additional views of
the audio equipment designer eing com ined
with that translation process.
In order to make the task of positioning the
loudspeakers less complex we would like to
make the following suggestions. That most
valua le commodity, time, is the most
important ingredient in this process. Be
prepared to make small changes over longer
periods of time.
Select four musical passages that you are
familiar with, that can fulfil the following
tests.
• They should all e stereo recordings.
• Select one with a distinctive and easily
heard human voice. Spoken voice is
ideal.
• Select one passage with a full
orchestra like The Pines of Rome.
• Select one that is very emotional for
you.
• Select one that has a strong rhythm as
in the case of dance music.
You should appraise the performance of the
loudspeakers according to our needs ased
upon the tests a ove.
Cinema S stems
• There is no industry standard for the
positioning of speakers for home
cinema, ut there are some facts that
should e considered when creating
such a dedicated environment.
• Tactic® drive units are not shielded
and should not e placed within
750mm of a television (cathode ray
tu es). All Wilson Benesch speakers
should e over one metre from any
television. The angle from the screen
should ideally e etween 110 and
130 degrees.
• The loudspeakers should e identical.
However Wilson Benesch
loudspeakers use identical drive units
and tweeters, so it is possi le for the
system to e comprised of more
powerful channels at the front of the
room and smaller systems eing
exploited for the surrounding field.
• The Centre channel is a critical
component in any quality cinema
system. It handles more than
dialogue, which the ear is very
sensitive to, as we are all very familiar
with what the human voice should
sound like.
• All Wilson Benesch loudspeakers can
e classified as full range systems.
• Configure the su woofer just for
LFE.
Spikes
The spikes are supplied installed with some
systems and so great care should e taken
when handling these systems. By careful tests
you can adjust the speaker oth in terms of
toe in, and in terms of angle of position,
should you wish to align the speaker you
should arrange for an assistant to assist in this
task. The position of the tweeter has een
designed to function est for listeners seated
in conventional relaxed seating positions. If
required, for other situations such as listeners
on higher seating or standing, the speakers
can e tilted ack so as to incline the tweeter.

5
Magnet Precautions
The motors used in all Wilson Benesch
speakers are uilt from the most powerful
magnetic material in the world, Nd.Fe.B. Do
not ring any metallic o jects or sensitive
electronic, electro magnetic or mechanical
systems into close proximity of these devices,
this includes pace makers or other critical
devices. The compan cannot accept
responsibilit for an damage or injur
caused to an such s stems as a result of
accidental exposure. Extreme care must
be taken with all Wilson Benesch Isobaric
speakers as the Tactic® motor is exposed
in these s stems.
Terminals
Wilson Benesch recommends the use of 8mm
Ring or Spade Connector ca le terminations.
A spanner is provided to nip up the gold
plated nuts, ut e careful. Please do not over
tighten the terminals. The terminals also
allow the use of anana plugs.
Running In (70 hrs)
Like anything of good quality a period of
running in tends to see improvements in
performance. The speaker ca inet requires
time to settle in to its surroundings. Climatic
and humidity variations will take time to
adjust to, and until such adjustments have
een made the speaker will not perform at its
est. The drivers require time to ed in
physically, and relax materially. The car on
panels actually improve in structural integrity
as they age. The quality of the sound that you
hear when you first use your Wilson Benesch
speakers, will improve quite significantly over
time, though the change will not e instantly
percepti le. Allow at least seventy hours of
running in efore making any su ject
judgements of the speakers performance.
Surface Finish
Car on fi re is a unique material with unusual
physical and visual characteristics. We like to
remain truthful a out the fi rous nature of
the material as opposed to concealing or
o scuring it.
The natural wood components are
manufactured using real-wood veneers. They
will darken over time and, depending on the
climatic and heating conditions will stress
relieve. This is a natural phenomenon that
may cause slight changes in the dimensions of
the wood. These are typically impercepti le.
The surface finishes applied to all Wilson
Benesch loudspeakers require no further
attention other than the occasional dusting.
Treat the driver cones with respect and they
will last a decade with relative ease.
Due to the angle of the ca inet top on the
Chimera, A.C.T. and Discovery, the
appearance of stains as a result of the
inconsiderate placing of a glass is of course
impossi le. Care should e taken with the
acrylic tops on the Arc, Discovery and Curve.
A very soft lint free clot should e used to
gently wipe this surface.
With a little care the speakers will look as
good in ten years as they do today and will
pro a ly sound even etter!
Other Adjustments
Under no circumstance should you make any
adjustments to the systems parts. Any
adjustments not descri ed a ove as required
y the setting up procedure will nullify all
guarantees.
Upgrades
Wilson Benesch upgrades made availa le
as a result of technical advances in drive
units will e made availa le through
Wilson Benesch dealers. Qualified persons
should only install these systems. Wilson
Benesch cannot e held responsi le for
any damage to the loudspeaker or any
other related equipment such as amplifiers
if any other person undertakes this
upgrade.
Should there e any question regarding
the performance of this system you
should refer to your dealer immediately
for advice and or assistance. If in the
unlikely event that the pro lem cannot e
dealt with y your dealer do not under any
circumstances return the goods to Wilson
Benesch without prior agreement with the
company

The Odyssey
Series
Arc
Centre
Curve
Discovery
Chimera
Act
The Odyssey series was conceived from the Bishop Project and incorporates the same
technology throughout the range. All the designs within the range are completely original in
thought and execution and represent the State of the Art in loudspeaker design and
manufacturing.
Alloy structures and complete monocoque car on fi re composite systems ensure that the energy
within the ox remains where it should. This enclosure is quite simply eyond the limitations of
all currently used materials used y other loudspeaker manufacturers and is years ahead of its
time.
The a ility to com ine the systems is axiomatic, as all the drivers including the tweeter are
identical. Su sequently the system can e expanded or adapted to any conceiva le situation
whether it is a reference two channel system or cinema surround field system.
The phase response characteristics are identical also due to the use of simple two and a half way
crossover techniques.
Systems can e single or i wired or to provide even greater control i-amping techniques can e
used.
A large range of finishes are availa le as standard and espoke finishes in a vast array are availa le
in oth veneers and polymer finishes.

White Paper
On The A.C.T. Loudspeaker System
From
Wilson Benesch
Cabinetr materials replaced b engineering materials
Car on composite is of course the principal structural component in the new A.C.T. A complete
U section not dissimilar to the monocoque in the Odyssey series is now used in the new A.C.T.
ut here we see the original and distinctive twill weave that has always een a part of the A.C.T.
One and A.C.T. Two systems.
Baffle construction
The alloy affle has decreased in size in an effort to ring the drivers closer than previously
possi le with the MDF structures. A formida le com ination of steel and aluminium is used as
the reference for the latest version of the Tactic® drive unit 18mm thick at the affle.
Latest version of the Tactic® Drive unit
This has also enefited from changes to its mass oth in the coil and the diaphragm the principal
players in the dynamics of any drive unit. An edge wound aluminium coil has seen the mass of
the coil halved this has provided the opportunity to stiffen the diaphragm further and reduce the
overall mass without any negative side effects. The net result is a etter controlled, more dynamic
loudspeaker drive unit that sets new standards of performance.
Crossover t pe and location
Although the crossover is fundamentally the same its location in the spine and at the ottom of
the ca inet in the case of the ass inductor sees these sensitive components installed away from
the air orne energy that can excite these systems in an undesira le way. Bi wiring has replaced
the tri wiring option and the terminal is now the same type and location as the Chimera.
Silent port arrangement
The porting arrangement has also een completely redeveloped, the mid range system is now
vented at the ase of the ca inet via the spine system at the ack of the enclosure. This virtually
eliminates the possi ility of hearing any noise from the port whilst at the same time reducing any
effects relating to rear wall reflections when placed close to the rear wall. The port arrangement
for the ass is quite similar to the A.C.T. Two ut improved through a further development of
the port that now passes through a complex arrangement that sees the foot eing rought in to
play in an effort to reduce the high velocity movement of air still further.

13
Beaut
Aesthetically the forms are svelte and precise in appearance. A more contemporary and attractive
design that is clearly in keeping with current expectations for interior design conscious consumers
who demand the very highest quality without sacrificing sonic performance. Build quality is
exceptional with all parts assem led to the finest tolerances. Finishes are extensive and availa le
in oth straight veneer, urrs and irds eye wood types. For the demanding consumer we can
offer espoke options that mean that if it can e extracted without harming the planets
ecosystems we can produce it. Architectural polymer finishes in Silver and lack are also availa le
and again colours can e specified that are capa le of eing matched to any interior colour
scheme as another espoke option.
Improving performance whilst reducing cost to the consumer
The A.C.T. One price has een very sta le with only one price rise in seven years. We can say
with some pride that contrary to the norm in the industry all these changes have een introduced
without incurring a price increase and in actual fact the price has een reduced! These
considera le changes will underline Wilson Benesch’s position at the forefront of technology at
this sector of the market. The A.C.T. One roke the mould and challenged the loudspeaker
industry of 1995. It was always going to e a hard act to follow ut in this solution we elieve
that we have excelled ourselves. The A.C.T. One was always held in high esteem y all who heard
it, and it is still used today as the Reference Loudspeaker system y the largest audio journal in
the UK. It won twelve awards from every corner of the glo e and sales have remained uoyant
throughout its seven year reign, a C.V. that few if any could compare.
The new sound
The new A.C.T. sounds even more like an electrostatic in the way that it conjures a three
dimensional sound field with even more dynamism than the A.C.T. Two. It is more accurate and
the increase in mass gives it an authority and presence that will em arrass other systems costing
many times more. It is possi le to say that the quality of reproduction from such a diminutive
and elegant enclosure has never een achieved efore and it is without dou t an appropriate and
fitting tri ute to the A.C.T. One and A.C.T. Two, designs which it replaces as of Novem er
2002.
