PLACEMENT
Stereo
CS 60RDT
Before deciding where to place your CS Series speakers, survey
your room and think about placement, keeping the following
points in mind, and using Figure 1 as a guide:
Model CS 60RDT has the ability to play two channels through one
loudspeaker, thanks to its dual-tweeter/dual-voice-coil construction.
Since the tweeters are close together, generally they should be
aimed away from each other for best coverage.
• For best results, place the speakers 6'–8' apart.
For two-channel (stereo) applications (e.g., as a single speaker in a
remote room of a distributed audio system), install the CS 60RDT
speaker centrally in the ceiling for best stereo imaging, pivoting
the tweeters so that one points toward the left and the other toward
the right of the listening position.
• When installing in the wall, position each speaker so that the
tweeter is as close to ear level as practical.
• Refer to“Home Theater”below if you also plan to use the
speakers in a home theater system.
The CS 60RDT may also be used to play the left and right surround
channels in a 5.1-channel home theater system, in which case it
should be mounted in the ceiling slightly behind the listening
position, centered from left to right and with the tweeters pointing
toward the left and right of the listening position, aimed slightly
downward. For 7.1-channel systems where it is desired to use two
CS 60RDT speakers, one to play both the left surround and
surround back channels and the other to play both the right
surround and surround back channels, mount each CS 60RDT
speaker in the ceiling, slightly behind the listening position, one
closer to the left side of the room and the other closer to the right
side.Aim the tweeters, on each speaker, away from each other,
toward the front and rear of the room.
Home Theater
For front-channel use, place one speaker on the left and another
on the right along either side of the television.
A center channel speaker should go directly above or below the
television and can be an in-wall or freestanding center channel.
For surround channel use, install the speakers alongside the
listening position.
NOTE: An Infinity powered subwoofer will add impact and
realism to both music and film soundtracks. Contact your
Infinity dealer for recommendations on subwoofer models for
your application.
Proper placement of the speakers is an important step in
obtaining the most realistic soundstage possible.These
recommendations are for the optimum placement of the
loudspeakers. Use these placement recommendations as a guide.
Slight variations will not diminish your listening pleasure.
INSTALLATION
The CS Series in-wall speakers were designed to be easily
installed. However, if you are unsure of your ability to properly
install these loudspeakers, please contact your dealer or a
qualified installer.
Ideally, the front speakers should be placed the same distance from
each other as they are from the listening position.
In a home theater configuration, the two surround speakers should be
placed perpendicular to the listening position. If that is not possible,
they may be placed in a wall/ceiling behind the listening position.

Turn Off All Power
Before completing the installation, you must connect your
speakers to your system. First, turn off all audio-system power.
Use high-quality speaker wire to make your connections. Use at
least #16-gauge speaker wire with polarity coding. Heavier
gauge wire is recommended for larger distances. Consult the
chart above or your dealer for recommendations.The side
of the wire with a ridge or other coding is usually considered
positive polarity (i.e., +). Also, consult the owner’s manuals
that were included with your amplifier or receiver to confirm
connection procedures.
Observe polarities when making speaker connections, as shown
in Figure 3. Connect each + terminal on the back of the
amplifier or receiver to the respective + (red) terminal on each
speaker. Connect the – (black) terminals in the same way.
Important!
Do not reverse polarities (i.e., + to – or – to +) when making
connections. Doing so will cause poor imaging and diminished
bass response. Be certain that positive and negative wire strands
are completely isolated to avoid short circuits that may damage
your equipment.
