2. DISTANCE TO THE LOUDSPEAKERS
Because of the DDC technology, the
Confidence loudspeakers will deliver excellent
imaging in applications with small as well as
wide listening distances. Room interaction will
be minimized, though the room’s influence
on the sound quality still must be taken into
consideration.
The distance to the speakers ultimately
depends on the room’s shape, size and your
personal listening taste. Please note that when
listening to the speakers from a wide distance,
the room must allow the speakers to be posi-
tioned with a wider distance between them as
well. To maintain a balanced sound integration
from the driver arrangement, a 2.0 meters
distance from the listening position to the
loudspeakers is a good starting point during
experimentation.
The listening distance to each speaker should
be identical.
3. DISTANCE TO BACK AND SIDE WALLS
When loudspeakers are positioned too close to
walls, the sound quality can be restricted.
Every loudspeaker not only disperses sound
energy directly into the room, but also to
the side and even backwards. As a result,
time-delayed reflections occur and add to the
original music signal.
The Confidence models were developed to be
placed free-standing, and therefore they reach
their optimum performance when positioned
as clear of any walls as possible. To reduce
possible influences from the back and side-
walls, the distance to these boundaries should
ideally not be less than one-half (0.5) meter.
To minimize low frequency reflections, which
will be heard as a thickening of the sound, the
Confidence models can be adapted to the
room’s acoustic character by using foam plugs
in the bass reflex port. This will essentially
attenuate the room-induced boost in the low
frequency range by dampening the deep fre-
quencies, yielding a more clear and tight sound
and minimized backwave reflections when the
loudspeaker is positioned near rear walls.
With the Confidence models, it will be more
important to address the issues of the side and
rear walls’ influence on the sound, as the DDC
technology will minimize any effect of the
more difficult to address ceiling and floor
boundaries.
