example) may help balance the sound. Conversely,
reducing the amount of soft furnishing may help
brighten a dull sound.
Some rooms suffer from "flutter echoes" – echoes that
bounce between parallel room boundaries. Flutter
echoes can colour the sound of the speakers in the
room. Test for flutter echoes by standing in the middle
of the room and clapping your hands. Flutter echoes
can be reduced by placing irregular shaped items or
non-reflective surfaces, bookshelves, rugs or pictures
for example, on one of the offending walls or floor.
Running-in Period
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.
However, longer run-in periods (as long as a month)
have been reported and there is evidence to suggest
that this has little to do with the speaker changing and
more to do with the listener getting used to the new
sound. This is especially so with highly revealing
speakers such as these, where there may be a
significant increase in the amount of detail compared
with what the listener has previously been used to; the
sound may at first appear too "up front" and perhaps
a little hard. After an extended period of time, the
sound will seem to mellow, but without losing clarity
and detail.
Aftercare
The cabinet surfaces usually only require dusting. If
you wish to use an aerosol or other cleaner, remove
the grille first by gently pulling it away from the
cabinet. Spray aerosols onto the cleaning cloth, not
directly onto the product. 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. The grille fabric
may be cleaned with a normal clothes brush whilst the
grille is detached from the cabinet. Avoid touching the
drive units, especially the tweeter, as damage may
result.
Please be aware that, like all natural materials, the
wooden cabinet of the speaker will respond to its
environment. Keep the product away from sources of
direct heat such as radiators and warm air vents to
avoid the risk of cracking. The wood is treated with an
ultra-violet resistant lacquer to minimise changes in
colour over time, but a degree of change is to be
expected. This effect may be particularly noticeable
where areas kept in shadow change more slowly than
other areas. Colour differences may be rectified by
4
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.
