Owner's manual

Introduction
Thank you for choosing B&W.
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.
Unpacking
(Figure 1)
• Fold the carton flaps right back and
invert the carton and contents.
• Lift the carton clear of the contents.
• Remove the inner packing from the
product.
We suggest you retain the packing for
future use.
Check in the carton for:
• 2 Foam bungs.
• 8 Self-adhesive rubber pads.
• 1 International warranty booklet.
Positioning
(Figure 2a)
Mount the speakers on firm dedicated
stands that place the tweeters
approximately at ear level. Bookshelf
mounting is possible but alows less
opportunity for optimising the sound. The
shelf or stand used will affect the sound
quality of the speaker. The B&W FS-CDM
stand is designed to fit the CM™2 and is
recommended.
As an initial guide:
• Position the speakers and the centre of
the listening area approximately at the
corners of an equilateral triangle.
• Keep the speakers at least 1.5m apart to
maintain left-right separation.
Stray magnetic fields
The speaker drive units create stray
magnetic fields that extend beyond the
boundaries of the cabinet. We recommend
you keep magnetically sensitive articles
(television and computer screens, computer
discs, audio and video tapes, swipe cards
and the like) at least 0.5m from the
speaker.
Connections
(Figure 3)
All connections should be made with the
equipment switched off.
There are 2 pairs of terminals at the back of
the speaker which permit bi-wiring if
desired. On delivery, the separate pairs are
connected together with high-quality links
for use with a single 2-core cable. For
single cable connection, leave the links in
place and use either pair of terminals on
the speaker.
Ensure the positive terminal on the speaker
(marked + and coloured red) is connected
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.
To bi-wire, remove the links by loosening
the terminal caps and use a separate
2-core cable from the amplifier to each pair
of terminals. This can improve the
resolution of low-frequency detail. Observe
the correct polarity as before. When
bi-wiring, incorrect connection can also
impair the frequency response.
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, make sure that all the
connections in the installation are correct
and secure.
Moving the speakers further from the walls
will reduce the general level of bass. Space
behind the speakers also helps to create an
impression of depth. Conversely, moving
the speakers closer to the walls will
increase the level of bass.
If you want to reduce the bass level without
moving the speakers further from the wall,
fit the foam bungs in the port tubes.
(Figure 4)
If the bass is uneven with frequency it is
usually due to the excitation of resonance
modes in the room. Even small changes in
the position of the speakers or the listeners
can have a profound effect on how these
resonances affect the sound. Try mounting
the speakers along a different wall. Even
large pieces of furniture can have an effect.
If the central image is poor, try moving the
speakers closer together or toeing them in
so they point just in front of the listeners.
(Figure 2b)
If the sound is too harsh, increase the
amount of soft furnishings 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.
Reduce them by the use of irregular
shaped surfaces such as bookshelves and
large pieces of furniture.
Ensure the speaker stands are firm on the
floor. If you have a carpet, use carpet-
piercing spikes and adjust them to take up
any unevenness in the floor.
