B&W 800 Series Diamond
The home of the world's most advanced and innovative hi-fi and home cinema loudspeakers.
One material sums up the quest for perfection in sound reproduction more than any other. Diamond. It’s the ultimate tweeter material – and the magic ingredient in the flagship 800 Series Diamond. It’s part of the reason why 800 Series speakers have become legendary among professional recording studios and serious sound enthusiasts alike. And now, for the first time, you can hear the incredible precision and clarity of diamond in every speaker in the range. The very best just got even better. And perfection just got even closer.
The 800 Series Diamond gives you the best possible sound quality in every application, from professional recording to domestic hi-fi and home theatre.
Diamond for every occasion
You don’t have to be an Abbey Road studio engineer to appreciate the stunning realism of the 800 Series Diamond. The range encompasses speakers of all sizes and applications, from mighty studio monitors to bookshelf speakers that will fit snugly into domestic spaces of any size. But while every speaker is different, they have a several key features in common: a tweeter made from pure diamond, and sound quality that will leave you speechless.

805 Diamond
You asked for it. And now you’ve got it. The 805 Diamond is an industry world-first – the only speaker of its size and type to incorporate true studio-grade technology in the form of a diamond dome tweeter. Experience remarkable, lifelike sound from a discreet speaker that fits almost anywhere.
Welcome to the revolution
Diamond dome tweeters have long been considered an exclusive luxury in the world of audio – a refinement to be reserved only for the most expensive, studio-sized loudspeakers. No longer. The 805 Diamond is nothing less than a revolution in speaker design: the first speaker of its size and at this price point to come with a diamond tweeter. Because studio-quality sound shouldn’t just be for studios.
Fits anywhere
Small but perfectly formed, the 805 Diamond will fit almost everywhere. Tucked away on a bookshelf or positioned on its specially designed stand, it’s perfect for smaller listening spaces. And it will serve equally well as the rear channels of a home theatre system. With 805 Diamond, you can now bring superb, breath-takingly realistic sound to places you never thought possible.

804 Diamond
As wonderfully versatile as its smaller brother the 805 Diamond, the elegant, floorstanding 804 Diamond has an even more commanding acoustic presence, thanks to a true three-way design incorporating two Rohacell® bass units, an FST™ midrange and a diamond dome tweeter delivering pin-sharp clarity all the way up the frequency range. A brilliant all-round performer for any occasion.
Diamonds as standard
The hypothetical perfect tweeter is one that balances infinite stiffness with near-zero density. Only one material on earth comes close to matching those properties: diamond. Thanks to modern scientific techniques, we can grow diamond, like a crystal, to form the optimum tweeter dome shape. The result is truly exceptional sound at high frequencies. And it comes as standard with every speaker in the range, including the 804 Diamond.
Shock absorber
For a long time, B&W thought their Kevlar® midrange cones couldn’t get any better – but then they came up with the fixed suspension transducer (FST for short). FST enhances the properties of Kevlar by acting like a circular shock absorber around the cone, absorbing the sound-smudging bending waves that travel outwards to the perimeter. A midrange driver never sounded cleaner, or more responsive.

803 Diamond
The 803 Diamond might look almost as imposing as the 802 Diamond, but thanks to its smaller footprint and more traditional cabinet design, it will fit more comfortably into a home environment. With three massive 7” Rohacell® bass drivers, it delivers almost as much bass as the 802 Diamond, filling even the largest of domestic rooms with rich, stunningly lifelike sound.
The home-sized studio speakerThe design and proportions of the top two speakers in the range are derived at for sound acoustic reasons – but understandably, not everyone wants the visual disruption that such a radical piece of furniture can create in a home environment. The 803 Diamond takes up less space and is arguably easier on the eye – but thanks to its three bass drivers, it generates a sound that’s almost a match for its bigger brothers.
Force of attraction
For the 800 Series Diamond range, the science of magnet motor design has been refined to a fine art. Each of the 803 Diamond’s three bass drivers are powered by a dual magnet motor system, creating a more symmetrical magnetic field and reducing harmonic distortion. Meanwhile a unique quad magnet design keeps the tweeter running cool and smooth, even at the highest frequencies.

ASW DB1
The cleanest, fastest subwoofer ever
When it comes to getting maximum enjoyment from movies and music, bass is where the action is. And for serious bass, you’re going to need a seriously powerful subwoofer.
But power is only half of the story. To fully convey the visceral impact of an explosion, or the thrilling sweep of an orchestral score, you also need control. The kind of control that stops sonic distortion dead in its tracks, no matter how hard you push the speaker. And the fast response required to bring nuance and pin-sharp definition even to the biggest, most powerful bass effects.
Control
It’s the rare quality that puts the DB1 head and shoulders above the rest. Combine it with the awesome power derived from its dedicated amplifier, and you have a subwoofer that puts you right at the heart of the action.
Music & Movies
Big movie effects demand big bass. It’s the reason why most subwoofers are built simply to provide prodigious levels of sound – often at the expense of subtlety and musicality. Here at Bowers & Wilkins, a passion for music has driven what we do from the beginning. So it should come as no surprise that the DB1 sounds superb whatever you’re listening to, be it Die Hard or Debussy.
Perfect Partner
The DB1’s incredible precision and accuracy raises subwoofer performance to a whole new level. It’s so good, in fact, that we’d recommend it as the perfect partner for the top-of-the range 800 Series Diamond – the same speakers used by studios like Abbey Road and Skywalker Sound, and regarded by many audiophiles as the best in the world. Praise indeed.
Laws of adaption
The size and shape of a room can affect the sound of a subwoofer in all sorts of unpredictable ways, exaggerating some frequencies and suppressing others. With DB1 we’ve found a way around this problem, building in adjustable digital settings that allow you to adapt the speaker to its environment. So every DB1 is a perfect match for the room it’s in.
Stirred. not shaken
Even the sturdiest subwoofers tend to wobble in the face of the biggest, bass-heavy movie sound effects, transmitting unwanted sound through the cabinet walls. DB1 stands firm under pressure, thanks not only to its rock-solid construction, but also to the ingenious design of its twin drivers, facing away from each other in perfect mechanical balance. It’ll shake the earth, not the cabinet.
