5. Running In
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.
6. 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.
