Summit floorstanding loudspeaker Manuel D’Utilisation
By now 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.

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 any 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 prob-
lems 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 ade-
quate 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.

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. However, MartinLogan’s
unique controlled dispersion electrostatic transducer
inherently minimizes side wall reflections—a position as
little as two feet from the side walls often proves adequate.
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.

Experimentation
Toe-in—Now you can begin to experiment. First begin
by toeing your speakers in towards the listening area and
then facing them straight into the room. You will notice
the tonal balance and imaging changing. You will notice
that as the speakers are toed-out, the system becomes
slightly brighter than when toed-in. This design gives you
the flexibility to compensate for a soft or bright room.

Generally it is found that the ideal listening position is with
the speakers slightly toed-in so that you are listening to the
inner third of the curved transducer section. A simple, yet
effective method to achieve proper toe involves sitting at the
listening position, holding a flashlight under your chin and
pointing it at each speaker. The reflection of the flashlight
should be within the inner third of the panel (see figure 4).
