Two Channel Loudspeaker Positioning; Cinema Systems; Spikes - Wilson Benesch Arc Owner's Manual

Two channel loudspeaker
positioning
There are no objective criteria that can be
used to state precisely where loudspeakers
should be positioned. Should any individual or
company suggest that there is, they should be
regarded as special people and treated with a
great deal of caution. In the global scenario,
our loudspeakers are driven by unique systems
that are selected by the owner because of
particular virtues. Every listening room is as
individual and unique in character as the
owner. Compound this complex picture with
the combination of different equipment.
Consider the changeability of rooms, if the
room is dressed with heavy curtains simply
changing the curtains position can alter the
whole balance 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 subtle balancing act.
The goal of high performance audio systems
is accurate reproduction. The information, be
it in groove or pit format should be
transcribed, amplified and converted back into
sound energy without the additional views of
the audio equipment designer being combined
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
valuable 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 be 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 your needs based
upon the tests above.

Cinema Systems

There is no industry standard for the
•
positioning of speakers for home
cinema, but there are some facts that
should be considered when creating
such a dedicated environment.
Tactic® drive units are not shielded
•
and should not be placed within
750mm of a television (cathode ray
tubes). All Wilson Benesch speakers
should be over one metre from any
television. The angle from the screen
should ideally be between 110 and
130 degrees.
The loudspeakers should be identical.
•
However
loudspeakers use identical drive units
and tweeters, so it is possible for the
system to be comprised of more
powerful channels at the front of the
room and smaller systems being
exploited for the surrounding field.
The Centre channel is a critical
•
component in any quality cinema
system.
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
•
be classified as full range systems.
Configure the subwoofer just for
•
LFE.

Spikes

The spikes are supplied installed with some
systems and so great care should be taken
when handling these systems. By careful tests
you can adjust the speaker both 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 been
designed to function best for listeners seated
in conventional relaxed seating positions. If
required, for other situations such as listeners
on higher seating or standing, the speakers
can be tilted back so as to incline the tweeter.
