Important Safety Instructions
- Read these instructions.
- Keep these instructions.
- Heed all warnings.
- Follow all instructions.
- Do not use this apparatus near water.
- Clean only with a dry cloth.
- Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
- Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
- Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for the replacement of the obsolete outlet.
- Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
- Only use attachments/accessories specified by the manufacturer.
- Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
- Unplug this apparatus during lightning storms or when unused for long periods of time.
- Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
WARNING:
To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.
- When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
- Check that there are no cables under the carpet that may be damaged by the spike feet. Do not walk the product on the spike feet as this may cause them to become detached from the cabinet and cause damage. Take care not to impale yourself with the spike feet.
- For continued protection against fire hazards, use fuses only of the correct type and rating. Mains fuses are located inside the appliance as well as on its back panel. Replacement of the internal fuse should be entrusted to an authorized operative. User-replaceable fuse types are shown in the specification.
- Isolation of the appliance from the power supply is by means of removal of the power cord from the rear of the appliance or removal of the power cord from the wall power outlet. Either the wall outlet or the rear of the appliance must remain freely accessible at all times while the apparatus is in use.
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.

An example of such a feature would be a 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 an acoustically transparent cloth that matches the décor, 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 optimize 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.
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. This manual covers the CT SW10, CT SW12, and CT SW15 subwoofers and their matching SA1000 automated rack mount power amplifier.
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. 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.
The nearer the ratio is to 2:1 the better, as it indicates a good current capability. 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.
Aftercare
The cabinet surfaces usually only require dusting. 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.
