This product has been designed and manufactured to the highest quality standards. However, if something does go wrong with this product, B&W Loudspeakers and its national distributors warrant free of charge labour (exclusion may apply) and replacement parts in any country served by an official B&W distributor. This limited warranty is valid for a period of five years from the date of purchase or two years for electronics including amplified loudspeakers. where the equipment can be serviced. You can call B&W in the UK or visit our web site to get the contact details of your local distributor. To validate your warranty, you will need to produce this warranty booklet completed and stamped by your dealer on the date of purchase. Alternatively, you will need the original sales invoice or other proof of ownership and date of purchase. so make sure the volume is not too restricted by cross studs. 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. 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). Owner's manual Introduction Thank you for purchasing Bowers and Wilkins CWM 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 CWM speakers are primarily intended for in-wall applications, but may equally well be used in-ceiling. They feature adjustment for tweeter output level so that their performance may be tailored to a wide variety of practical conditions. 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.

Front speakers for audio or home theatre Best imaging for 2-channel is obtained when the speakers are mounted in the wall 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) to the left and right 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, choose between above or below the screen depending on which is nearer ear height. (figure 2) 2 3 a. b. c. d. Surround speakers The speakers should be positioned 60cm (2 ft) or more above head height. 5.1 channel Check the contents This pack should contain: 2x wall frame/baffle with drive units and crossover 2x grille with backing scrim fabric 2x paint mask 2x mounting template e. 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) f. 4 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 10 litres (0.4 cu ft), How to claim repairs under warranty Should service be required, please follow the following procedure: 1 If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased. If the equipment is being used outside the country of purchase, you should contact B&W national distributor in the country of residence who will advise 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 figure 11 to calculate the minimum gauge of cable required. 2 2 Existing drywall construction (retrofit) Position the template at the desired location of the speaker. The template is marked with both vertical and horizontal centre lines to aid alignment. Trace round the outer edge of the template and cut neatly just inside the line. To improve the mechanical integrity of the wall and reduce the likelihood of rattles, we recommend you apply a bead of wood glue or mastic along the joints between the back of the plasterboard and the studs in the vicinity if the speaker. Run the cable to the aperture, allowing enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure. plastering to avoid rattles as a result of the plaster shrinking away from the back box as it dries. If using plasterboard, stick the sheets to the surfaces of the back box using flexible mastic. Rout out the aperture using the flange as a guide. Depending on the diameter of the router, you may need to square off the corners with a saw. In all cases, we recommend not using cement or mortar to fix the back box into the brick or blockwork. rattles are best avoided by using flexible mastic and wedges. (figure 7) Français Garantie limitée Cher Client, Bienvenue à B&W. Ce produit a été conçu et fabriqué en vertu des normes de qualité les plus rigoureuses. Toutefois, en cas de problème, B&W Loudspeakers et ses distributeurs nationaux garantissent une main d'oeuvre (exclusions possibles) et des pièces de rechange gratuites dans tout pays desservi par un distributeur agréé de B&W. Cette garantie limitée est valide pour une période de cinq ans à compter de la date d'achat ou une période de deux ans pour les composants électroniques, y compris les haut-parleurs amplifiés. Damping the cavity Fill the wall cavity or back box, but not the space immediately behind the speaker, with unlined fibreglass or mineral wool matting. The packing density should be just enough to comfortably prevent the material from dropping or sagging over time. In an open wall cavity, fill to a distance of at least 30cm (1 ft) above and below the speaker. (figure 8) IMPORTANT: Ensure that the materials you use meet local fire and safety regulations. New drywall construction The speaker can be installed once the wall is completed in the same manner as retrofitting, but it is easier to position and cut the hole if the optional pre-mount kit is used before the plasterboard (sheetrock) is fitted. Staple or nail the PMK to the studs as described in the instructions with the kit. Run the cable and secure it to the fixing point on the PMK. Allow enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure. Results are affected by how well the plasterboard is attached to the studs and we recommend gluing as well as screwing or nailing the panels to the studs in the vicinity of the speaker. Once the board is fitted, the inner flange of the PMK serves as a guide for a hole router or saw. If extra acoustic isolation to adjoining rooms is required or some protection against the spread of fire, use the optional back box in place of the PMK. Follow the instructions with the back box for fitting and running the cable. When fitting the plasterboard, use mastic between the sheets and the back box to avoid rattles. Rout or saw out the speaker aperture using the backbox flange as a guide. Depending on the diameter of the router, you may need to square off the corners with a saw.
