If the sound is too bright, increasing the amount of
soft furnishing in the room (heavier curtains for
example) may help balance the sound. Conversely,
reducing the amount of soft furnishing may help
brighten a dull sound.
For the most discerning listening, remove the bass/
midrange grilles by gripping around their edges and
gently pulling them away from the cabinet.
The performance of the speaker will change subtly
during the initial listening period. If the speaker has
been stored in a cold environment, the damping
compounds and suspension materials of the drive
units will take some time to recover their correct
mechanical properties. The drive unit suspensions
will also loosen up during the first hours of use. The
time taken for the speaker to achieve its intended
performance will vary depending on previous storage
conditions and how it is used. As a guide, allow up to
a week for the temperature effects to stabilise and 15
hours of average use for the mechanical parts to attain
their intended design characteristics.
5. Aftercare
The cabinet surfaces will usually only require dusting.
We recommend you use the cloth supplied with the
product. If you wish to use an aerosol or other cleaner,
apply the cleaner onto the cloth, not directly onto the
product and test a small area first, as some cleaning
products may damage some of the surfaces. Avoid
products that are abrasive, or contain acid, alkali or
anti-bacterial agents. Do not use cleaning agents
on the drive units. Avoid touching the drive units as
damage may result.
Whenever Bowers & Wilkins speakers are finished
in real wood, the finest veneers are selected and
treated with an ultra-violet resistant lacquer to
minimise changes in colour over time. Nevertheless,
like all natural materials, the veneer will respond to
its environment and a degree of colour change is to
be expected. Colour differences may be rectified by
exposing all the veneer surfaces equally and evenly
to sunlight until the colour is uniform. This process
can take several days or even weeks, but may be
accelerated by careful use of an ultra-violet lamp.
Wood veneered surfaces should also be kept away
from direct sources of heat such as radiators and
warm air vents in order to minimise the possibility
of the wood veneer cracking.
The tweeter housing has a textured surface finish that
may collect superficial marks when handled and should
be cleaned by wiping the supplied cleaning cloth
around the housing, in-line with the surface texture.
The leather covered surfaces of your 800 Series
Diamond loudspeaker can be dusted using a soft,
dry cloth. Stains can be removed from the leather by
moistening a microfibre cloth with warm water and
using it to dab the leather until clean. Do not rub the
cloth on the leather or use cleaning detergents or
leather polish as doing so may cause damage to the
product.
