Every room has its own distinctive acoustics, which influence the way we experience sound
from a speaker. The sound you hear consists of direct sound from the speakers and reflected
sound from the floor, ceiling and walls. The latter will affect how you experience the sound.
As a basic rule, try to avoid large, hard and reflective areas in the immediate vicinity of your
loudspeakers as it will typically cause strong reflections, which might disturb the precision and
spatial effect of the sound reproduction. Reflection might be suppressed by positioning e.g. a
plant between the speaker and the reflecting surface. Soft items such as carpets, curtains etc.
might help if the sound is too bright. Both the amount and quality of the deep bass depend on
the size and shape of the room, and the position of the speakers. Positioning the speakers near
a side or back wall will accentuate the bass. A corner location will accentuate it even more, but
will also increase the reflections.

Like any mechanical system, a loudspeaker requires a "running-in" period to perform at its
best. You will experience a gradual increase in sound quality during the first period of use. The
break-in period will vary depending on use and playback volume. You should expect up to 100
hours of playback until maximum performance is reached. Unlike other mechanical systems,
the life-span of a loudspeaker is increased by normal, regular playback of music.

Clean the cabinets with a soft, dry cloth. If the cabinets are dirty, wipe with a soft cloth dipped in
all-purpose cleaner and then well wrung out. Be very careful when wiping the speaker cones,
as they are very fragile. Grille fronts can be cleaned with a clothes brush and wiped with a well
wrung, lint-free cloth and mild all-purpose cleaner.
8.1 AVOID DIRECT SUNLIGHT
The surfaces of the speakers may fade or become discoloured over time when exposed to
direct sunlight. Therefore avoid positioning the speakers in direct sunlight.
