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 toHome Theaterbelow 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.
