Introduction

Dear customer,

Thank you for purchasing a Bowers and Wilkins Custom Theatre system.

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.

Custom Theatre speakers are specifically designed to be built into the fabric of the listening room or into custom furniture as part of a fully designed theatre concept. To that end, they incorporate several features that enable them to be adapted to a wide range of installation conditions and deliver superb sound quality. However, they specifically do not incorporate features found on some other B&W products that are not appropriate to this type of installation. An example of such a feature would be tweeter on top, which only operates well with a free-standing speaker. Furthermore, because of the normal custom install

practice of hiding built-in speakers with acoustically transparent cloth that matches the decor, all the models except one are supplied without grilles. The exception is the CT8 DS surround speaker, which needs to protrude into the room in order for the side-firing drivers to operate properly.

No matter how good the speakers themselves may be, 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.

Although the speakers are semi-active and require an active crossover, all power amplification must be separately sourced. Each CT8 LR, CT8 CC and CT8 DS requires two channels of power amplification, or three if used with a CT8 SW subwoofer. This allows the user maximum flexibility in choosing these components.

The CT8 SW subwoofer, unlike the majority of subwoofer currently available, does not contain its own power amplifier and is used in a different manner than is usual. The original concept of home theatre based on various Dolby Digital and DTS systems advocates five or more main channels plus a single Low Frequency Effects (LFE) channel. The main channels contain full range signals and the LFE channel contains special effects up to approximately 140Hz . Recognising that many people do not want five or more full-range speakers in one room, Dolby Digital and DTS systems allow for the main channels to operate with small speakers having a restricted bass extension. The lowest frequencies from these channels are filtered off and added to the LFE channel to be reproduced by a subwoofer. The filter cut-off frequency is normally set at around 80Hz , the rationale being that sound gets progressively less directional the lower the frequency and localisation becomes less important. This is true to some extent, but the ears can process directional information at very low frequencies and the more the bass of the main channels is extended, the more realistic the sound stage becomes. Many high-end processors offer lower filter cut-off frequencies for this very reason.

To preserve this directional information, a CT8 SW may be added to each of the main channels as desired, extending the frequency response well below 20Hz . The minimum recommended configuration is to assign one subwoofer to each of the front left and right channels, restoring some directional information to the action directly on the screen and full directional information to 2-channel audio programme. The sense of spatial acoustic improves as more subwoofer are added to the remaining channels. If higher sound levels are required for larger listening environments and greater realism, up to two subwoofer may be added to each main channel. (It should be noted here that the addition of more subwoofoers to any single channel requires an adjustment of the subwoofer

output level of that channel's CT8 XO in order to restore the correct tonal balance.) The LFE channel is then distributed to all the main channels that have a subwoofer assigned by the simple action of configuring the surround processor as if there were no subwoofer present and specifying where the LFE signal should be routed. Strictly speaking, the phrase "no subwoofer" here means "no subwoofer dedicated to the LFE channel".

Safety Warning!

A CT800 system is capable of producing very high sound pressure levels. Prolonged exposure to high sound levels can lead first to temporary and later

permanent hearing damage. Do not exceed recommended Leq (equivalent sound level) exposure levels, for example, those specified in ISO 1999:1990.

Running In and Ancillary Equipment Ancillary Equipment

Speakers of this ability deserve signals of the highest quality. Choose your electronic equipment and interconnecting cables with care. We can give guidance on what to look for when choosing ancillary equipment, but cannot recommend specific items. The standards of such products are improving all the time and your dealer will be able to demonstrate a variety of suitable up-to-date products.

In the specification we recommend a range of amplifier powers. The higher figure is defined by the power handling capability of the speaker. When calculating the power handling, it is assumed that the amplifier is not run into clipping, which distorts the frequency power spectrum of the signal, and that the signal is normal programme material. Test tones from oscillators and the like are not applicable. The lower figure is the minimum we consider necessary to achieve reasonable listening levels without audible distortion in the smaller room (less than 60m^3 or 2000 cu ft). The higher the power you use, the less likely you are to experience amplifier clipping.

You can often tell how good an amplifier is at driving complex speaker loads by looking at its power rating into both 4Ω and 8Ω loads. The nearer the ratio is to 2:1 the better, as it indicates a good current capability.

In order to reduce the effect the cable has on the frequency response of the speaker to inaudible levels, the impedance of the cable at all frequencies (measuring both positive and negative conductors in series) should be kept as low as possible and certainly below 0.1 . At low frequencies, the DC resistance of the cable is the dominant factor and you should choose a gauge of wire sufficient to achieve the impedance requirements over the length of cable you need to use. At mid and high frequencies the inductive component of the impedance can dominate the DC resistance. This and other properties influenced by the detailed construction of the cable become important.

Running In

The performance of the speakers will change subtly during the initial listening period. If they have been stored in a cold environment, the damping compounds and suspension materials 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 speakers to achieve their intended performance will vary depending on previous storage conditions and how they are 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 a new sound. It is especially so with highly revealing speakers such as these, where there may be a significant increase in the amount of detail portrayed compared to 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 speaker cabinet surfaces and the casing of the CT8 XO usually only require dusting. If you wish to use an aerosol cleaner, remove any speaker grilles first by gripping round the edges and gently pulling them away from the cabinet. Spray onto the cleaning cloth, not directly onto the cabinet. The grille fabric may be cleaned with a normal clothes brush whilst the grille is detached from the cabinet.

When replacing grilles, ensure that the pegs are correctly aligned with the receptacles in the cabinet before pushing into place.

Avoid touching the drive unit diaphragms, especially the tweeter, as damage may result.
