Infinity CLASSIA C255ES Owner's Manual page 3

IMPORTANT NOTE: The set of drivers that share a panel with the
Surround Mode Configuration switch in Figure 3 should be installed
toward the front of the room. It does not matter whether the tweeter
is positioned above or below the woofer. (The Infinity logo can be
removed and inverted for proper orientation.) This will ensure
proper operation and performance, should the Monopole or Dipole
position on the Surround Mode Configuration switch be selected.

Placement (Application 2)
When using the C255ES as a rear speaker(s) in a 6- or
7-channel home theater system, refer to Figures 4 and 5.
The speaker(s) should be mounted on the rear wall facing the
listening area, between the side channel speakers. If you are
using one rear speaker, it should be mounted as close as
possible to the center of the listening area. When using two
rear speakers, they should be spaced evenly within the width
of the listening area.
Setting the Surround Mode Configuration Switch
When used as a rear channel speaker in a 6- or 7-channel
system, it is recommended that the Surround Mode Configuration
switch be set to "Bipole, " as shown in Figure 6.
Placement (Application 3)
The C255ES also possesses the unique capacity to behave as
two distinct loudspeakers from one enclosure.This allows you to
use a single C255ES for both the left and right rear speakers in
a 7-channel system.
To utilize the C255ES in this application, follow these simple steps:
1. Decide where you want to mount the speaker. Ideally, it should
be mounted in the center of the rear wall, similar to how it
would be mounted in a 6-channel system (Figure 4).
2. Loosen the terminals and remove the strapping bars that
connect the two sets of terminals (Figure 9).
3.To ensure proper left/right connections, make sure that the
speaker is in the "upright" position.The label on the back of
the speaker should be readable, not upside down.
4. Connect the speaker wire for the right rear speaker to
the bottom set of terminals (Figure10).
5. Connect the speaker wire for the left rear speaker to
the top set of terminals (Figure 10).
6. Set the Surround Mode Configuration switch to the "Bipole"
position (Figure 6).
