Owner’s manual

Introduction

Thank you for purchasing Bowers and Wilkins CWM LCR8 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.

The CWM LCR8 is an audiophile quality in- wall speaker that may be used in vertical or horizontal orientation, the latter aesthetically better for centre channel 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

The outer carton should contain:

In pack 1:

Wall frame,

Grille with fabric scrim backing,

Mounting template,

Paint mask.

In pack 2:

Baffle with drive units and crossover, Fixing screws.

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. Refer to the section drawing of the speaker and 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

20 litres (0.7 cu ft), so make sure the

volume is not too restricted by cross studs. This is particularly important when the speaker is installed in horizontal orientation for centre channel applications. In order to fit the speaker horizontally, part of one vertical stud will have to be removed and this will necessitate the use of two cross studs to maintain the strength and integrity of the wall.

In solid wall construction, be prepared to provide a cavity in the wall that extends outside the boundaries of the speaker's frame, otherwise bass performance will be compromised. 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. As such 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 wall in vertical orientation, with the tweeters approximately at ear height and 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) from the edges of the screen and they and the centre speaker should be as near the centre height of the screen as possible. For a centre speaker, horizontal orientation is normally preferred for aesthetic reasons and you should choose between above or below screen mounting depending on which is nearer ear height. (figure 2)

Surround speakers

The speakers should be positioned with the tweeters 60cm (2 ft) or more above head height.

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)
