Running-In; Aftercare - Bowers & Wilkins 805 Diamond Owner's Manual

5. Running-In

The performance of your speakers may change subtly
during the initial listening period. If they have 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 suspension will also loosen
up during the first hours of use. The time taken for the
speakers to achieve their intended performance will
vary depending on previous storage conditions and
how they are 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

800 Series Diamond 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 surface 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.
