600 Series
www.bowers-wilkins.com
It’s that time again. When B&W unveils the latest
edition of its 600 Series. It’s been going on since the
mid-1990s. Even on its debut the 600 Series swept up
five star reviews and product of the year awards for its
affordable, audible brilliance. Every three years or so since
then, as new editions have appeared, it’s been the same
story. The new 600 Series – the fourth generation – has
been a little longer coming, so the heat’s been off the
competition. But it’s back. And it’s better, sharing more
leading-edge technologies with our top-of-the-range 800
Series. There’s a wider choice of finishes, a fresh new look
and a step forward in sound quality that raises the bar to
a whole new level. It’s been a wait, but it’s worth it.

There’s no room for dreams in business. That’s
what we’re told. B&W is different. Its success stems from
the dream of founder John Bowers to create the perfect
loudspeaker – one that neither adds to nor takes away from
the recorded performance. And, in the laboratories and
listening rooms of our dedicated Research Establishment in
southern England, that’s been our goal from day one. The
design breakthroughs we’ve made and the technologies
we’ve developed along the way have helped to create
award-winning loudspeakers at every level of the market.
By working with respected studios like Abbey Road, we’ve
satisfied the world’s most demanding listeners. The dream
is our business. And today, through networks such as our
newly-founded Society of Sound, we’re finding performers,
technicians and customers who share it. We’re getting
closer all the time.

You might think that seeing a movie at home can
never compare to seeing it at the cinema. Well,
that’s what the B&W 600 Series is here for: to
bring the big screen experience into your home.
With a sound system that can deliver every word,
whisper, pin drop and tyre screech in super-sharp
clarity, from any point in your room, you’ll find
yourself living every moment. And, when you’re
winding down from that experience, switch the
system to audio to enjoy your favourite music in
revelatory sound quality.
The 683 Theatre is one of three suggested
packages designed for different roomscapes.
It’s the reference 600 Series home theatre system,
put together to fill large, open spaces effortlessly
with rich, deep, detailed sound. Prepare yourself
for the big sound experience, fronted by a pair of
uncompromising 683 floorstanders. Think you
saw and heard it all at the cinema? Think again.

Behind the scenes. The creation of the 600 Series has
engaged just about everyone at Bowers & Wilkins in some
way. Here’s a look at some of the detail and thinking from
two of the people involved.
Mike Gough, Senior Product Manager
When you are faced with creating a new
600 Series, how does your approach differ
from that for a reference level range?
In one respect, surprisingly little. After all, our
customers’ passion for music is governed by their
hearts not wallets. And from an execution point
of view we’re tied by the same laws of physics at
every level. Of course, the challenges are different
but we expend just as much energy solving them.
Can you explain how the challenges differ?
Normally, new technologies are developed for
high-end products. There the challenge is all about
pushing absolute boundaries and there’s usually a
good deal of heartache in the perfecting process.
It may be learning about new materials or getting
to grips with a new manufacturing process. It’s
very time consuming and can be very expensive
to perfect. Once that part of the process is over,
however, you don’t have to go through it again
when you want to apply it to another product.
The challenge with value products is how to apply
what may be an expensive feature more cost
effectively. Interestingly, they’re not all expensive to
manufacture. Take Flowport™, for example. It costs
no more to mould a dimpled port than it does a
plain one, so that feature made its way into most of
our products across the board very quickly.
Give me an example of how you cost
engineered an expensive technology.
I’ll give you two that are related. For many years,
because of the cost of manufacture, Kevlar® cones
were restricted to 800 Series products and the first
two 600 Series did not feature them except for the
midrange driver of the largest floorstander. We then
considerably slicked up our production methods
and not only made the cones more affordable but
more consistent in performance. This time round,
we have used our FST™ midrange driver for the first
time in 600 Series. This is a really great driver - lots
of detail and resolution - and has helped make
the reputation of 800 Series products. This time
though, we already had the optimum production
methods in place, so nothing to gain there. What
we did was use a much simpler mounting method
than the single point tension method of the 800
Series. You can do that sort of stuff at the high
end but that you can get a big chunk of the benefit
at 600 Series level is a pretty good deal for the
customer.
A lot of what makes a great speaker is
down to the final voicing. Do the 600 Series
engineers go about this in a different way
from the 800 Series engineers?
If I say at the outset that it’s the same team across
the board, you’ll realise that the answer is no. One
of the advantages of this is that you get the same
dedication to performance targets. Once you have
worked on high end products, you can’t lower your
standards. I’ve stopped counting the number of
times I have sat in on listening sessions and been
amazed at the level of performance those guys can
wring out of speakers.
Dr. Gary Geaves, Head of Research
One of the important acoustic changes in
this new 600 Series is in crossover design.
Why is this area of acoustic design so
crucial?
Sufficient coverage of the full audible spectrum
requires at least two drive units, covering the low,
mid and high frequency bands. It is necessary to
filter out the high and low frequencies respectively,
in order that the two drivers combine in the correct
manner. This filter is known as the crossover, and
it is just as critical to the overall sound as any other
element in the system. Experience has shown that
the simpler we can make the crossover filter, the
better the sound. And the better the drivers, the
simpler the crossover required. In this new 600
Series we have really done a lot of work in this area
which has resulted in just one capacitor for the high
frequency part of the crossover - as uncomplicated
a format as it gets.
B&W also talks about the selection of these
crossover components as being in itself
crucial.
Yes. With a loudspeaker design where the drive
units are very high resolution, it is often the case
that filter components which appear to have
identical stated specifications can sound drastically
different. We’re researching this to find out why
but we can definitely hear huge differences that we
currently don’t really know how to measure. The
ear is a remarkably sensitive device!
How do you choose these components
then?
The final selection of components and therefore
the overall ‘tuning’ of the loudspeaker must, of
necessity, be done by subjective analysis i.e.
listening to music. And not just in one room with
one type of equipment - in as many rooms as
possible with all manner of different partnering
equipment. This aspect of acoustics is actually
as much of a skill as the more obviously scientific
areas like material science and it’s why B&W has
always dedicated a large portion of a loudspeaker’s
development time to listening. It’s also the area
of development where we’ll involve our friends at,
say, Abbey Road Studios to get as broad a set of
opinion as we can.

Treble. Mobile phones, DVD players, car navigation
systems… Sooner or later, most technological advances
become accessible. Few, though, will generate as much
sheer pleasure as the innovations now found in the 600
Series.
When we develop a breakthrough technology for
one of our studio-standard ranges, every other
B&W product feels the benefit. What was state-ofthe-art in the high-end series becomes state-ofthe-art in more affordable ranges. Everything that
goes into a B&W speaker has a pedigree. The
600 Series tweeter is a case in point. Its tubeloaded design, which spirits away unwanted sonic
radiation from behind the dome, first appeared in
our convention-busting Nautilus™ speaker. The
aluminium dome itself, bonded resolutely to the
voice coil, achieves truer-than-ever frequencies well
past the upper limit of human hearing.
Neodymium magnets similar to the kind used in
the tweeter of the 800 Series replace the ceramic
magnets of the previous 600 Series tweeter. More
compact, they allow the separation between the
centres of the midrange and tweeter to be reduced,
which makes for a more focused sound ‘image’.
Other refinements, to the magnet pole and the
surround material, have lowered distortion and
further sharpened the imaging. All of which adds up
to a tweeter of such high quality that it requires only
a 1st-order filter, whose simplicity helps to preserve
the full purity of the signal.
www.bowers-wilkins.com
Midrange. Owners of earlier 600 Series speakers will
be wondering how we could improve on the clarity and
detail of a midrange drive unit that’s already in a class of
its own. That’s just the kind of challenge we like.
In all our 600 Series midrange/bass units the
distinctive yellow woven Kevlar® cone snuffs out
the kind of concentric standing waves that build
up in standard, homogeneous cones, while a light,
airy ‘open’ chassis cuts down echo from behind
the cone. But, to the midrange of the three-way
683 speaker, we’ve been able to add something
even more special. We call it a ‘fixed suspension
transducer’, or FST™ for short. It sounds complex,
but it’s not. It’s simple, and it sounds wonderful, but
until now it has only been seen in B&W’s audiophile
ranges, such as the 800 Series.
The FST™ is a ring of foam whose mechanical
properties exactly match those of the woven
Kevlar® cone, which gives it magical properties
over the bending waves that travel outwards
through the cone, to its edge. With a conventional
roll surround, these energies would be reflected
back into the cone and smudge the sound.
The FST™ soaks them up, like a circular shock
absorber around the cone’s edge. What you hear is
a cone moving even more freely and responsively: a
midrange that’s top of the range.
www.bowers-wilkins.com
Bass. When push comes to shove, you have to be serious
about bass. At B&W, it’s a science. We test materials,
structures and circuits to their limit to get better bass for
your buck.
You might not think a material like paper would
tie in very well with a B&W bass driver. Turn the
volume up on one of our 600 Series subwoofers,
for instance, and you could probably shake
wallpaper off walls. So it might surprise a lot of
listeners to find that paper plays a vital part in
what they’re hearing. In our ASW608, ASW610
and ASW610XP subs, the bass driver diaphragms
are constructed from a finely-tuned mix of paper
pulp, Kevlar® fibres and resin, which provides
the stiffness needed to withstand the tremendous
physical forces exerted by the voice coil and
pressures inside the cabinet.
For the 683 bass drivers, which operate to
higher frequencies than the subwoofers, that
paper/Kevlar® mix is closely bonded to an
aluminium front skin and the unit features our novel
‘mushroom’ construction in which the cone, dust
cap and voice coil bobbin are bonded together
like a ring girder. Extra measures to extend the
performance.
Ultra-solid construction - that’s the key to slamming
bass, drum kicks and special movie effects.
Deformation is minimised; bass precision, power
and enjoyment are maximised.
www.bowers-wilkins.com
Finishes. We don’t believe in spoiling your enjoyment of
what you hear by designing speakers that you don’t want
to see. Choose from a wider-than-ever set of finishes and
tailor your 600 Series speakers to their setting.
Speakers, after all, are furniture. They have a form
as well as a function. You’ll find the craftsmanship
and quality of finish on B&W 600 speakers reflect
the high standard of engineering and innovation
inside them. For the new series, we have widened
the choice of cabinet finishes and remodelled the
speaker facades to echo currents in contemporary
furniture design.
A matt, soft-touch front surface and elimination
of visible screws around the drivers creates an
understated, seamless appearance, complemented
by a new, brushed aluminium, diamond-cut logo
plate that encompasses the tweeter. There are
three cabinet veneers available: our traditional
Black Ash; the Light Oak that proved popular for
the 600 Series 3 and a smooth Red Cherry.

Want to ride with Hopper and Fonda in Easy Rider?
Fly into the Death Star with Luke? Or eavesdrop
on the neighbours in Rear Window with James
Stewart? If your requirements from a home theatre
system don’t run to maximum power, but you’d
still like sound that can drop you headfirst into the
action, we suggest the 684 Theatre. Featuring a
pair of 2½-way, floorstanding 684s, two 686s in
the rear position, an HTM62 centre speaker and an
ASW610 subwoofer, it can recreate movie sound
and music in totally believable 3D detail and power.
www.bowers-wilkins.com
Home theatre packages. With two bookshelf speaker
models, two floorstanders, two centre speakers and three
subwoofers in the 600 Series, there’s a lot of potential
ways to assemble a home theatre system. Here are three
groups that, to our ears, go together as harmoniously as
the Beach Boys or Ladysmith Black Mambazo.
685 Theatre
The most compact of the three set-ups, the 685
Theatre is a bookshelf-based arrangement for more
enclosed listening environments. With an ASW608
subwoofer bringing bass aplenty, it still packs all the
punch you’ll need.
Main: 685
Centre: HTM62
Surround: 686
Subwoofer: ASW608
684 Theatre
For maximum detail and impact in medium-sized to
large rooms, team up a pair of 2½-way 684s with a
larger subwoofer, an HTM62 centre speaker and a
pair of 686s in the rear position.
Main: 684
Centre: HTM62
Surround: 686
Subwoofer: ASW610
683 Theatre
If you’re watching movies and listening to music
in a large, open space, you need a system with
authority as well as attention to detail. The 683
Theatre will command the largest domestic spaces
with ease.
