Placement
LISTENING POSITION
Your speakers should be placed approximately
two to three feet from the front wall, the wall in
front of the listening position, and about two feet
from the side walls. Your sitting distance should
be further than the distance between the speakers
themselves. You are trying to attain the impression
of good center imaging and stage width.
There is no exact distance between speakers
and listener, but there is a relationship. In long
rooms, naturally, that relationship changes. The
distance between the speakers will be far less
than the distance from you to the speaker system.
However, in a wide room, you will still find that
if the distance from the listener to the speakers
becomes smaller than the distance between the
speakers themselves, the image will no longer
focus in the center.
Now that you have positioned your speaker
system, spend time listening. Wait to make an
major changes in your initial setup for the next
few days as the speaker system itself will change
subtly in its sound. Over the first 72 hours of play
the actual tonal quality will change slightly with
deeper bass and more spacious highs resulting.
After a few days of listening you can begin to
make refinements and hear the differences.
THE WALL BEHIND THE LISTENER
Near-field reflections can also occur from your
back wall (the wall behind the listening position).
If your listening position is close to the back wall,
these reflections can cause problems and confuse
imaging quality. It is better for the wall behind you
to be absorptive than to be reflective. If you have a
hard back wall and your listening position is close
to it, experiment with devices that will absorb
information (i.e. wall hangings and possibly even
sound absorbing panels).
THE WALL BEHIND THE SPEAKERS
The front surface, the wall behind the speakers,
should not be extremely hard or soft. A pane
of glass will cause reflections, brightness and
confused imaging. Curtains, drapery and objects
such as bookshelves can be placed along the
wall to diffuse an overly reflective surface. A
standard sheet rock or textured wall is generally
an adequate surface if the rest of the room is not
too bright and hard. Walls can also be too soft.
If the entire front wall consists of heavy drapery,
your system can sound dull. You may hear muted
music with little ambience. Harder surfaces will
actually help in this case. The front surface ideally
should be one long wall without any doors or
openings. If you have openings, the reflection
and bass characteristics from each channel can
be different.
THE SIDE WALLS
A good rule of thumb is to have the side walls
as far away from the speaker sides as possible.
both speakers. Starting with one speaker, connect
the right channel to the lower binding posts and
the left channel to the upper binding posts. Repeat
the same procedure for the other speaker. Connect
the left preamplifier outputs to both inputs of the left
channel amplifier and the right preamplifier outputs
to both inputs of the right channel amplifier (Fig. 5).
ACTIVE BI-AMPLIFICATION
We do not recommend active bi-amplification. The
internal crossover can not be bypassed. This con-
nection method seriously degrades performance.
