Owner’s manual

Introduction

Thank you for purchasing Bowers and

Wilkins CCM speakers.

Since its foundation in 1966, the continuing

philosophy of B&W has been the quest for

perfect sound reproduction. Inspired by the

company’s founder, the late John Bowers,

this quest has entailed not only high

investment in audio technology and

innovation but also an abiding appreciation

of music and movies to ensure that the

technology is put to maximum effect.

These CCM speakers are intended for in-

ceiling applications.

However, no matter how good the speakers

themselves, they will not deliver their full

potential unless properly installed. Please

read through this manual fully. It will help you

optimise the performance of the system.

B&W distributes to over 60 countries

worldwide and maintains a network of

dedicated distributors who will be able to

help should you have any problems your

dealer cannot resolve.

Check the contents

This pack should contain:

2x Frame/baffle with drivers and crossover

2x Grille

2x Paint mask

2x Mounting template

Choosing the position

Check that there is no conflict with other

installations (pipe work, air conditioning,

power cabling etc.). In existing drywall

construction, use a stud-finding tool to

map the construction accurately and a pipe

detector to scan the proposed installation

position.

Ensure that there is enough clearance

behind the plasterboard (sheetrock) for the

clamps to swing out fully.

Avoid installing the speakers in the same

cavity as flimsy ducting, which may be

induced to rattle.

The speakers are designed to operate

satisfactorily in a wide range of cavity

volumes, ideally above 10 litres (0.4 cu ft),

so make sure the volume is not too

restricted.

The speakers are balanced for half-space

mounting (ie flush in a ceiling or soffit).

Placement near a wall/ceiling junction or in

a corner may give rise to too much bass

and a boomy quality to the sound. Try to

keep the speakers at least 0.5m (20in) from

wall/ceiling edges.

The following sections give guidance on

optimum positioning, but this may be

modified in line with domestic constraints.

WARNING: The speakers produce a static

magnetic field. They should not be placed

within 0.5m (20in) of equipment that may

be affected by such a field (eg Cathode

Ray Tubes in TVs and Personal

Computers).

Front speakers for audio or home

theatre

Best imaging for 2-channel is obtained

when the speakers are mounted in the

ceiling, making an angle between 40º and

60º at the centre of the listening position.

(figure 1)

For multi-channel home theatre the left and

right speakers should be approximately

0.5m (20 in) to the left and right of the

screen and about 0.5m (20 in) from the

plane of the screen or from the front wall in

the case of an audio-only installation.

(figure 2)

Surround speakers

The speakers should be positioned in the

ceiling about 0.5m (20 in) away from the

wall.

5.1 channel

The horizontal angle to the centre of the

listening position should be approximately

120º round from the centre of the screen.

(figure 3)

6.1 channel 

Position two speakers to the sides in line

with the centre of the listening area and

one centrally behind the listeners (figure 4)

7.1 channel 

Position two speakers to the sides in line

with the centre of the listening area and

two behind the listeners, subtending an

angle of approximately 40º. (figure 5)

Distributed audio

To maintain clarity and speech intelligibility,

it's important that listeners are never too far

off axis of the nearest speaker. The speaker

spacing will depend on the height of the

ceiling and the level of sound required.

More speakers played at a lower level will

give better clarity. We recommend that the

distance between adjacent speakers is no

more then 3 times the distance between

average ear height and the ceiling. For any

given spacing, there will be fewer weak

spots with a triangular grid than a

rectangular one. (figure 6)

PREPARING THE LOCATION

Choosing cable

Excessive resistance in the speaker cable

wastes power and alters the frequency

response of the speaker. Always try to keep

the resistance as low as possible with the

loop resistance preferably below 0.5 ohms

for non-critical applications and below

0.2 ohms for best results. Use the table of
