Infinity CAS 2.1 - Manual (Page 4)

The Infinity CAS in-wall speakers are designed to offer excellent
performance in any listening room or home theater system.
2-Channel or Front Left and Front Right
in a Home Theater System
Ideally, the speakers should be placed at least three feet away
from the side walls. In 2-channel applications, the two speakers
should be equidistant from your primary listening position. We
recommend that the angle formed between the speakers and the
listening area be between 45° and 60°. For example, if the
speakers are 8' apart, your listening position should be 8' to
12' from each speaker. See Figure 1.
When used as part of a home theater system, you may find that
you achieve excellent performance with the left and right
speakers spread apart even further.
Surround Channels in a Home Theater System
When used as part of a Dolby* Pro Logic,* THX ® or discrete 5.1-
channel home theater system, the surround speakers should be
placed at the sides of, and directed toward, the main listening
area. See Figure 2. If there are several rows of seating, place the
speakers, as described above, perpendicular to, or slightly
behind, the last row of seating.
When used as part of a 7-channel music or home theater system,
place the side speakers at the sides of and directed toward the
main listening area. If there are several rows of seating, place
the speakers, as described above, perpendicular to the middle
row of seating. The rear speakers should be placed along the
rear wall facing the front of the room. Each rear speaker should
be about 1/3 of the way into the room, but never to the outside of
the listening area. See Figure 3.

Listening Window Selector ™
We recognize that in-wall speakers are often installed in less than the ideal
locations described above. The CAS in-wall speakers include a “Listening
Window Selector” (Fig. 4) which allows the speaker to be fine-tuned for
optimal performance regardless of where the speaker is installed or the
listener is positioned. Choosing the correct position is simple.
If the speakers are installed and the listening position is usually as
described above, then set the switch to “Normal.”
Set the Listening Window to “Wide” if any of these situations occur:
• The speakers are installed with the
tweeter positioned either well above
or below ear level.
• The speakers are greater than
8' apart or are on different walls.
• There is no primary listening area or
the listeners tend to be moving around
such as during a party.
