User manual B&W CUSTOMER INSTALLATION SERIES BROCHURE

[. . . ] We refined and adapted those technologies for the 800 Series ­ our flagship range and the reference speaker of choice for demanding recording studios all over the world, from Abbey Road in London to Skywalker Sound in California. For Bowers, the pursuit of perfect sound was an all-consuming passion. We'll stop at nothing to get you closer to music as it was intended to be heard. The quest continues. The extraordinary clarity of Bowers & Wilkins' flagship 800 Series has seen the speaker adopted by many of the world's best recording studios. With its distortion-baffling tapering tubes and spiraling cabinet enclosure, the NautilusTM rewrote the rulebook on speaker design. The art of concealment It's one thing to design and make speakers that sound fantastic ­ but how do you maintain the same sound quality when those speakers are boxed into walls and ceilings? [. . . ] Of course, that still leaves you with the challenge of the colouration associated with mounting speakers in walls and ceiling. Back boxes help a lot, and we do offer advice on ways to improve the acoustic properties of stud walls. My advice would be to work with installers who understand the principles at work here ­ knowing the pitfalls can really help to improve the situation acoustically. Dr John Dibb, senior developement engineer at B&W Wall-to-wall innovation NautilusTM tapering-tube tweeters, a standard feature of top-range B&W models such as the 800 Series, can also be found in our Custom Installation speakers. Appearances can be deceptive. There might not be so much as a cable in sight, but this room is bursting with advanced speaker technology. Ingeniously concealed in the walls of any Custom Installation set-up you'll find B&W innovations that are the product of more than 40 years of intensive research and development. B&W remains at the forefront of speaker innovation thanks to our ongoing investment in science and technology. At our R&D facility in Steyning, Sussex, UK ­ otherwise known as the `University of Sound' ­ the brightest minds in acoustics develop and test every single component of our speakers until they're the best in their class, relentlessly pursuing any sound impurities until they have nowhere left to go. Thanks to this tradition of continual innovation, you'll find B&W-inspired technology everywhere that sound quality matters: in recording studios, in concert halls, and now tucked discreetly into the walls of your house as part of your own Custom Installation system. Kevlar® cone At the heart of the Custom Installation Series are cones of woven fabric. Whether the material is glass fibre or the familiar yellow of Kevlar®, the blend of fibre, resins and cone geometry produces an incredibly well controlled cone that reduces standing waves, minimises coloration and leaves transient `attack' unblurred. The result: remarkably clean, clear and dynamic sound. TM FST midrange driver The FSTTM (Fixed Suspension Transducer) midrange driver in our award-winning 800 Series adopted a `surroundless' design mounted in a more open chassis structure to reduce internal reflections of sound. The result: further reductions in coloration and enhanced clarity. Anodised aluminium dome tweeter Anodised aluminium domes are used on most models in the Custom Installation Series, and extend the high frequency response well above the limits of human hearing. The result: sweet and precise treble sounds that bring out the life in any performance. Cast drive unit chassis Most of the bass/midrange drive units used in this speaker series use die-cast chassis rather than the more common pressed steel chassis. The extra rigidity this brings to the speaker structure means that sound reproduction is more tightly controlled. The result: improved bass `speed' and `impact'. Tapered tube tweeter A monumental advance in loudspeaker technology, the tapered, tube-loaded tweeter absorbs unwanted sonic radiation from the rear of the diaphragm. The result: a more focused, natural high frequency sound, and the ability to deliver the ultrasonic frequencies of new digital formats with unparalleled precision. Living sound Our custom-installed speakers are equally at home bringing super audio to the interiors of superyachts and other oceangoing craft. With speakers from Bowers & Wilkins, a custominstalled audio system can be as simple or as ambitious as you choose. Then again, you might be after a system that pipes music to other rooms in your house, creating zones of sound that suit the moods of different areas and the tastes of different people. Or how about a full surround-sound home theatre system that's all but invisible when not in use?With our Custom Installation Series, music and movies can enrich your life, but needn't intrude into it. Study Kitchen and dining area Start small An entry-level system might comprise two pairs of Bowers & Wilkins in-wall speakers driven by a two-channel hi-fi system. Two pairs of near-invisible speakers are installed in the main living area and in the kitchen /dining area. The clutter of speakers, speaker stands and trailing cables that never did quite go with your décor is now gone forever. Living room Hall Cloakroom Bedroom Master bedroom Bedroom En-suite Shower room Hall Move on up This mid-range installation matches our custom installation speakers to a multi-room audio system. Discreet ceiling speakers in the master bedroom and En-suite add high quality sound that fits in easily with your lifestyle. Further in-wall speakers installed in the kids' bedrooms mean they can enjoy their own music, and their very own volume levels. Guest bedroom Bathroom Bedroom Utility room Home theatre Entertain the possibilities This whole-house system for the serious sound enthusiast embraces the full repertoire of audio expertise from Bowers & Wilkins.

Pre-mount kit Used in new drywall construction, the PMK identifies the position of the speaker during construction and provides a guide for cutting the plasterboard. Back box In drywall construction, the back box increases sound insulation to adjoining rooms and provides the fire safety barrier sometimes required by building regulations to prevent any fire present in the wall cavity from spreading into the room. Use it in solid construction to define a suitable working volume for the speaker, which may need to extend beyond the boundaries of the wall frame. Swing out dog fixings Swing out dogs provide a quick and effective method of securing the speaker to plasterboard. Initially stowed inboard of the wall frame, the dogs, or cantilever clamps, swing out behind the plasterboard on first turning the fixing screws. Further turning draws the dogs forward so the plasterboard is securely clamped between them and the flange of the wall frame. Pivoting/tilting tweeter It is not always possible to position the speakers for best coverage of the listening area. [. . . ]
