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.
