Owner's manual
Introduction
Thank you for choosing Bowers &
Wilkins.
At B&W, we have always followed John
Bowers' original philosophy of combining
the art and science of acoustic design to
create simply a better product, the
objective always being to get the
maximum amount of enjoyment and
fulfilment from listening to music or
watching movies.
The original Nautilus 800 Series
contained a raft of new technologies that
propelled it to being probably the best
selling high-end speaker range in the
world.
Since then, our team of research and
development engineers have been
striving to improve performance still
further. Here is a short summary of what
you will find new to this Series.
Bass cones throughout now feature a
sandwich construction of carbon fibre
skins bonded to a Rohacell foam core.
Rigid diaphragms are best for
reproducing bass frequencies and this
new construction allows us to thicken the
cone section, without suffering increased
mass. The extra thickness makes the
cone a more effective barrier to any
residual sound generated inside the
cabinet, giving tremendous dynamics and
timing to the bass, with the secondary
effect of cleaning up the midrange.
The FST midrange drive unit receives a
new chassis – stronger, yet maintaining
the maximum open area behind the
diaphragm to minimise reflective
obstruction and allow the free flow of air.
The response of all B&W tweeters
extends well into the ultrasonic region –
important to realise the potential of
SACD and DVD-A recordings. Now, the
top models in the Series feature diamond
dome tweeters. They're difficult and
expensive to manufacture, but they take
the response all the way to 80kHz in a
smooth manner, superior to most so-
called supertweeters.
Crossover design – getting the signal to
the drivers with the minimum of
degradation and blending them
seamlessly together – has long been
regarded as something of a black art. For
this Series, our engineers have taken a
sideways look at some of the traditionally
held views of filter design and bent the
rules a little. The result is imaging with
unsurpassed perspective and stability.
These are speakers of the highest calibre
and it's worth taking care with the set up
of your system, so please take time to
study this manual. Further information
can be found in the FAQ and Technology
sections of our web site
www.bwspeakers.com.
How to use the manual
This manual covers all the passive
speakers in the 800 Series. Even if some
of the information does not immediately
concern you, having it all in one place
will help you in the choice of extra
models you may require to expand your
system at a later date.
Each of the sections carries an
identification number and you will be
guided to the relevant sections by
