Owner’s manual
Thank you for choosing Bowers & Wilkins.
Please read this manual fully before unpacking and
installing the product. It will help you to optimise its
performance.
B&W maintains a network of dedicated distributors in
over 60 countries who will be able to help you should
you have any problems your dealer cannot resolve.
Environmental Information
All B&W products are designed to
comply with international directives on
the Restriction of Hazardous Substances
(RoHS) in electrical and electronic equipment and the
disposal of Waste Electrical and Electronic Equipment
(WEEE). These symbols indicate compliance and that
the products must be appropriately recycled or
processed in accordance with these directives.
Consult your local waste disposal authority for
guidance.
Unpacking
Check in the carton for:
2 Foam plugs
Rubber support pad
Support/wall bracket assembly
M6 cap head screw
Profiled washer
5mm Allen key
2 Mounting templates
Positioning
Home theatre front centre
(figure 1)
Position the speaker in horizontal orientation either
immediately above or immediately below the screen,
depending on which is nearer ear height.
Mounting
The speaker may be mounted on a shelf or bookcase,
or on the wall.
Stray magnetic fields
The speaker drive units create stray magnetic fields
that extend beyond the boundaries of the cabinet,
and, if placed close to the display, the display should
be a non-CRT (eg plasma or LCD) type. We
recommend you keep magnetically sensitive articles
(CRT television and computer screens, computer
discs, audio and video tapes, swipe cards and the
like) at least 0.5m from the speaker. LCD and plasma
screens are not affected by magnetic fields.
Mounting on a shelf or bookcase
To mount the speaker on a shelf or bookcase place
the rubber support pad in the desired location and
place the speaker centrally on the pad. The speaker
will adopt an appropriate vertical orientation thanks to
the profile of the support pad. (figure 2)

Mounting on the wall
We strongly recommend two people for the final part
of this job, one to hold the speaker and the other to
feed and connect the cable.
If you are running cable in the wall, the bracket can
also disguise the cable between its exit from the wall
and the speaker terminals, but only if the cable is
flexible enough. It is difficult to recommend a definite
maximum gauge, because cables vary significantly in
flexibility, depending on the insulation material. Solid
core cable is not recommended because of its lack of
flexibility and tendency to fracture when bent sharply.
4mm2 or 10AWG is probably a practical maximum
and, if the two insulated cores have an additional,
common outer sheath, it should be removed from the
point at which the cable exits the wall.
You should determine and mark the position of the
wall plate, and therefore the correct exit point of the
cable from the wall, before routing the cable.
The wall bracket assembly consists of a wall plate to
which is attached a 'wave' shape cover. Disassemble
the two parts by sliding one against the other before
pulling them apart. Note that in use, the two parts may
be required to mate in a different orientation from that
supplied.
There are two mounting templates (up tilt and down
tilt), because the wall plate is offset from the centre
line of the speaker. Furthermore, the wall bracket
supplied allows the speaker to swivel through
30 degrees, but only towards the opposite side to the
thicker part of the wall plate. (figure 3)
The templates show the position of the wall plate in
relation to the outline of the speaker when facing at
right angles to the wall (i.e. not tilted).
Using a spirit level, offer the appropriate template to
the wall with the outline in the desired position of the
speaker and mark 4 screw positions through the
marked slots. Drill and plug the wall for 4mm (No.8)
screws. If running cable in the wall, the exit clearance
hole should be positioned as shown by the shaded
area on the template.
Run the cable in the wall if desired. If the wall is
drywall construction, leave approximately 30cm (1 ft)
of cable protruding from the wall. Excess cable may
be pushed back into the wall void as the speaker is
mounted. If the cable is chased into solid wall
construction, the excess has to be accommodated
behind the 'wave' cover, so it is better to trim the
cable to no more than 15cm (6 in).
Screw the wall plate to the wall in the orientation
shown in figure 4.
Attach the 4 self-adhesive clear rubber strips from the
bracket kit to the underside of the wave shape cover as
shown in figure 5.
Attach the wave cover to the back of the speaker
using an M6 screw and profiled washer. (figure 6) The
thicker side of the 'wave' cover should be positioned
on the opposite side to the direction of tilt (ie to the
bottom for upward tilt and to the top for downward tilt.
(figure 3)
7211 XTC manual Inside

Feed the cable through the clearance holes in the
wave plate and connect to the terminals (figure 7),
following the instructions in the section “Connections”.
Taking care with the positioning of excess cable,
attach the wave cover to the wall plate.
Connections (figure 8)
All connections should be made with the equipment
switched off.
Connect the positive terminal on the speaker (marked
+ and coloured red) to the positive output terminal of
the amplifier and negative (marked – and coloured
black) to negative. Incorrect connection can result in
poor imaging and loss of bass.
Ask your dealer for advice when choosing cable. Keep
the total impedance below the maximum
recommended in the specification and use a low
inductance cable to avoid attenuation of the highest
frequencies.
Fine tuning
Before fine tuning, double check that all the
connections in the installation are correct and secure.
To reduce the bass level, fit a foam plug into one or
both the port tubes (figure 9). To access the ports,
remove the grille by gently pulling it away from the
cabinet.
If the sound is too harsh, increase the amount of soft
furnishing in the room (for example use heavier
curtains), or reduce it if the sound is dull and lifeless.
Test for flutter echoes by clapping your hands and
listening for rapid repetitions. They can be reduced by
the use of irregular shaped surfaces such as
bookshelves and large pieces of furniture.
Running-in Period
The performance of the speaker will change subtly
during the initial listening period. If the speaker has
been stored in a cold environment, the damping
compounds and suspension materials of the drive
units will take some time to recover their correct
mechanical properties. The drive unit suspensions will
also loosen up during the first hours of use. The time
taken for the speaker to achieve its intended
performance will vary depending on previous storage
conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and
15 hours of average use for the mechanical parts to
attain their intended design characteristics.
However, longer run-in periods (as long as a month)
have been reported and there is evidence to suggest
that this has little to do with the speaker changing and
more to do with the listener getting used to the new
sound. This is especially so with highly revealing
speakers such as these where there may be a
significant increase in the amount of detail compared
with what the listener has previously been used to; the
sound may at first appear too “up front” and perhaps
a little hard. After an extended period of time the
sound will seem to mellow, but without losing clarity
and detail.

Aftercare
The cabinet surfaces usually only require dusting. If
you wish to use an aerosol or other cleaner, remove
the grille first by gently pulling it away from the
cabinet. Spray aerosols onto the cleaning cloth, not
directly onto the product. Test a small area first, as
some cleaning products may damage some of the
surfaces. Avoid products that are abrasive, or contain
acid, alkali or anti-bacterial agents. Do not use
cleaning agents on the drive units. The grille fabric
may be cleaned with a normal clothes brush whilst the
grille is detached from the cabinet. Avoid touching the
drive units, especially the tweeter, as damage may
result.
