4 Speaker Placement
For optimal performance of the Statement e2 system we
recommend that the ESL/Transition towers be placed
approximately five to seven feet from the front wall (the
wall in front of the listening position) and at least two feet
from the side walls. The subwoofer towers should be
placed diagonally (or against a wall) in the front corners of
the room with at least one foot of clearance between the
woofers and the walls. The listening position should be
farther than the distance between the speakers them-
selves. What you are trying to attain is the impression of
good center imaging and stage width (see figure 1).
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.
Near-field reflections can 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 the quality of imaging. Actually it is better for
the wall behind you to be soft rather than bright. If you
have a hard back wall and your listening position is close
to it, experiment with devices that will soften and absorb
information (i.e., wall hangings and possibly even sound
absorbing panels).
The Wall Behind the Speakers
The front surface, the wall behind your speakers, should not
be extremely hard or soft. For instance, 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 soften a hard 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.
Sometimes walls can be too soft. If the entire front wall
consists of only heavy drapery, your system can sound too
soft or dull. You may hear dull, muted music with little
ambience. Harder room surfaces will actually help in this case.
The front surface should, optimally, be one long wall
without any doors or openings. If you have openings, the
reflection and bass characteristics from one channel to the
other can be different.
The Side Walls
The same requirements exist for side walls. Additionally, a
good rule of thumb is to have the side walls as far away
from the speaker sides as possible, minimizing near-field
side wall reflections. Sometimes, if the system is bright or
the imaging is not to your liking, and the side walls are
very near, try putting curtains or softening material directly
to the edge of each speaker. An ideal side wall, however,
is no side wall at all.
