WILSON BENESCH

Loudspeakers

The Bishop

All invention is simply an extension of man.

In the case of so many Wilson Benesch products not only are
the organic forms a clear manifestation of this philosophy but of
course, being carbon based, the links between the materials
employed in the construction of both the invention and Man are
clear. Materials technology is one aspect of the innovation that
has been brought to the domestic audio market by Wilson
Benesch. In a brief time the company has established itself
throughout the world and can be proud of its achievements.

We would like to thank you for sharing our view on what
represents good design by choosing our product above all
others.

We are confident that you will enjoy them as much as we do.

SETTING UP INSTRUCTIONS.

Important Points before Setting up

Carefully remove all packaging to gain access to the enclosures. During installation it is
helpful to have some one to assist as the speakers are quite heavy. Remove the tools and
spikes which are packaged separately. Please take a little time to read the rest of this booklet
before you begin setting up the system. You are advised to retain all packaging as it is
essential for shipping the system safely.

Patient and careful setting is essential to obtaining the maximum performance from this
system.
Note well the PRECAUTIONS stated below.

The NdFeb Magnets.
These are powerful motors do not bring any metallic objects or sensitive electronic electro
magnetic or mechanical systems into close proximity of these devices. The company cannot
accept responsibility for any damage to any such systems as a result of accidental damage.

Location
Please refer to the section at the back of this manual in order to determine position.

Spikes
The Spikes that have been specifically designed for the Bishop Loudspeakers should be
treated with caution. Turned from stainless steel which is very hard they are very sharp and
can easily inflict a severe wound to the unsuspecting and careless. When setting up the
speakers it is a good idea to leave the spikes off the speakers until the correct position for
their operation has been found.

PRECAUTION : WHEN POSITIONING THE SPEAKER IN
THE ROOM ENSURE THE SURFACE HAS NO SHARP
PROTRUSIONS WHICH WILL SCRATCH THE HIGH
QUALITY SURFACES OF THE ENCLOSURE.

When the position has been identified through listening tests, tape can be used to mark the
location prior to moving to one side to install the spikes. The vertical attitude of the speaker
can be varied. 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 fire the tweeter
upwards.

The spikes are manufactured by Wilson Benesch and have been engineered to uncommonly
high standards. They must be nipped up with the spanner provided in order for them to
function properly. Do not under any circumstances apply a great deal of force as this may
relieve the front spike boss from the foot. Large torsional loads are simply not necessary, just
enough force to gently lock the spike in place.

Terminals
PRECAUTION : DO NOT OVER STRAIN THE TERMINAL WHEN CLAMPING
CABLES.

(Wilson Benesch recommend 8mm Ring Connector cable terminations)

The Terminals have a crucial role to play which must be executed reliably over long periods
of time. Wilson Benesch terminals are a piece of industrial design in themselves. Their
elegance is born of simplicity and they achieve their purpose without compromise. They
were designed by Wilson Benesch in order to achieve the level of performance required by
the advanced design, of which they form an important part. They provide the shortest
possible route for the signal and in this aspect they out perform all other terminals currently
available. They are turned from a single bar of high purity brass and exploit the common nut
to ensure a reliable, vibration free termination of the cable to a massive surface area. Exploit
good quality 8mm diameter ring connectors and you will achieve the best possible link. You
can be sure that this inexpensive nut will be just as tight today as it will tomorrow or the next
year and once locked you can forget about it, out of sight, peace of mind cable terminations.
A spanner is provided to nip up the gold plated brass nuts, but be careful - brass is a soft
material.
The terminals also allow the use of banana plugs, but push in connectors always represent a
compromise over the superior screw thread and ring terminal connection described above.

Running In

Like anything of good quality a period of running in tends to see improvements in
performance. The speaker cabinet requires time to settle in to its surroundings. Climatic
variations and humidity will take time to adjust to and until such adjustments have been
made the speaker will not perform at its best. The drivers require time to bed in physically
and relax materially. The carbon panels actually improve in structural integrity as they age.
The quality of the sound that you hear when you first use your Bishops will improve quite
significantly over time though the change will not be instantly perceptible.

Surface Finish

Carbon fibre is a unique material with unusual physical and visual characteristics. We like to
remain truthful about the fibrous nature of the material as opposed to concealing or
obscuring it. It should be appreciated that whilst we take every effort to produce absolutely
perfect panels the occurrence of slight distortions in the fabric is inevitable. This
phenomenon is virtually impossible to control and is a natural characteristic of the material.
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 imperceptible.

The surface finishes applied to the Bishop Loudspeakers do not require anything 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 cabinet top, the appearance of stains as a result of the inconsiderate
placing of a glass is of course impossible.
With a little care the speakers will look as good in ten years as they do to-day and will
probably sound even better!
