Placement suggestions
Some people have restraints on speaker placement
because of room size, shape, or aesthetic considerations
and cannot meet one or more of the above placement
recommendations. They should not be discouraged from
investing in CS7.2s. It is our opinion that due to their
unipolar, point source radiation pattern, their very even,
wide dispersion, and the co-axial mounting of the tweeter
and midrange drivers, the CS7.2s fare better under
difficult circumstances than most other high quality
speaker systems. To help with placement, the following
suggestions are given as a starting point for a variety of
rooms.
Figure 3 shows an average size room. Generally, it is
best to start with short wall placement. This arrangement
provides sufficient space behind the speakers, allows the
listener to be far enough away from the speakers, and still
maintains some distance between the listening position
and the wall behind the listener. Since the speakers may
be near side walls in order to keep spacing between the
speakers wide, toeing-in the speakers is suggested.
Spacing
Because of their very wide, even dispersion of energy, the CS7.2s can usually be placed farther apart than most other
speakers. Optimum imaging is usually achieved when the speakers are almost as far apart as each speaker is from the
listener, although this will depend on the width of the room—narrow rooms require more narrow placement. If the
speakers are too far apart for the room, there will tend to be a “hole” in the middle of the soundstage; if they are too
close together, the image will be compressed and will not achieve optimum width.
Aiming
Depending on the room in which they are used, the CS7.2s can be aimed anywhere between straight ahead and
angled in so they point directly at the listener. Straight-ahead placement produces the widest, most natural
soundstage. However, if it is not possible to place the speakers the desired distance from side walls, a toed-in position
will reduce the strength of side wall reflections and, in these cases, provide a more focused spatial presentation.
Bass
In general, when a speaker is close to a wall, the bass response is stronger; placing a speaker in a corner will make it
even more so. The CS7.2s are designed to provide accurate bass when positioned away from all walls—the same
position that provides the best imaging.
Listener position
The CS7.2s provide broad dispersion of energy at all frequencies and therefore provide good results throughout a
large listening area. Best imaging is provided for a listener centered in front of the speakers. Optimum accuracy of
timbre and depth perspective is provided only for a seated listener who is eight or more feet away from the speakers.
