Sound
Die-cast drive unit chassis
When it comes to bass and midrange
frequencies, rock-solid construction is the key
to a controlled, precise sound from a drive unit.
So rather than using the usual pressed steel,
we’ve encased the bass/midrange drivers of
CI 600 Series speakers in a hardened die-cast
chassis. It makes for an extra rigidity, and a
cleaner, faster bass.
Dream weaving
Woven fabric cones are at the heart of our
Custom Installation Series speakers. Whether
the material is glass fibre or Kevlar®, the blend
of fibre, resins and cone geometry produces
an incredibly well-controlled cone that reduces
standing waves, minimizes coloration and
leaves transient ‘attack’ unblurred. The resulting
sound is remarkably clean, clear and dynamic.
Nautilus
TM
spiral diffuser
The Nautilus™ tube is one of our most famous
inventions - a horn that works in reverse by
sucking unwanted sound radiation away from
the back of a driver. A tube is all very well for
speakers with the space to accommodate
it – but what about a small ceiling-mounted
speaker? For the tweeters in the CI 600 Series
ceiling speakers, we’ve achieved the same
effect by flattening the tube and twisting it into
a spiral. So while the speakers are shallow
enough to squeeze into the most confined
spaces, the sound emanating from the front is
just as focused, and just as natural.
Look behind the grille of every one of our Custom
Installation speakers, and you’ll find advanced
Bowers & Wilkins acoustic technology that is the
product of nearly 50 years of intensive research
and development. Our innovations can be found
anywhere great 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.
