INFINITY REFERENCE SERIES
The Reference series of loudspeakers continues the longstanding Infinity
commitment to accurate sound reproduction. Our proprietary CMMD®
(Ceramic Metal Matrix Diaphragm) drivers, precision dividing networks
and rigid, well-braced enclosures combine to deliver uncompromised
performance in any stereo or multichannel home theater system.
UNPACKING THE SPEAKERS
If you suspect damage from transit, report it immediately to your dealer.
Keep the shipping carton and packing materials for future use.
PLACEMENT
Stereo
Before deciding where to place your Reference speakers, survey your
room and think about placement, using Figure 1 as a guide and keeping
the following points in mind:
• For best results, place the speakers 6 to 8 feet (1.8 to 2.4 meters)
apart. Angle each speaker toward the listening position.
• Position each speaker so that the tweeter is approximately
at ear level.
• Generally, bass output will increase as the speaker is moved closer to
a wall or corner.
• Refer to the “Home Theater”section on this page if you plan to use the
speakers for home theater reproduction.

Experiment with speaker placement to obtain the best bass level and
stereo imaging in your room.
Home Theater
For front-channel use, place one speaker on the left and another on the
right of the television monitor. Angle your front speakers toward the
listening position.
For surround-sound use, place the speakers alongside the listening
position. Final placement depends on room acoustics, availability of
space and your listening preference (Figures 2 and 3).
Place the center-channel speaker on top of or directly below the
television. Aim it toward the listening area.
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.

CARPET SPIKES – R253 AND R263
Use the included carpet spikes for stability if you are placing your tower
speakers on a thick rug or plush carpeting.The carpet spikes can be
manually screwed into each rubber foot on the base of the speaker.
RUBBER FEET – RC252 AND RC263
Peel the adhesive rubber feet from the included card and apply them to
the bottom of the center channel speaker.
RUBBER FEET – R152 AND R162
Peel the adhesive rubber feet from the included card and apply them to
the bottom of the bookshelf speakers.
CAUTION: Floorstanding (tower) loudspeakers have a high center of
gravity and may become unstable and tip over during earthquakes or
if they are rocked, tipped or improperly positioned. Consider anchoring
these speakers to the wall behind them, using the procedures and
hardware customary for anchoring bookcases and wall units. You are
responsible for proper installation and proper selection of hardware.
WALL-MOUNTING THE RS152
We have designed the RS152 speakers to mount directly onto a wall.
Each speaker has two keyholes on the back and will require two 1-1/2”
(38mm), #10 wood screws fastened to a wall stud. If a wall stud is
unavailable, install an anchor appropriate for a 1-1/2”, #10 screw.
NOTE: You are responsible for the correct selection and use of
mounting hardware (available through hardware stores) that will
ensure the proper and safe wall-mounting of the speakers.
Figure 4. RS152 keyhole location and rubber cushion placement.
Step 1.
Using the included wall template, mark the positions on the wall where you
would like to place the mounting screws.
Step 2.
Fasten two 1-1/2”, #10 wood screws to the wall using the markings
from Step 1 as your guide. Leave an 1/16”(1.59mm) space between
the wall and screwhead. If a wall stud is not available, use an
appropriate anchor.
Step 3.
To protect wall, attach 4 rubber cushions (included) in suggested
locations.
Step 4.
Place the speaker on the wall by aligning the keyholes on the back of
the speaker to the screwheads on the wall. Once positioned properly, the
speaker should slide down slightly and become secure.

WIRING THE SYSTEM
IMPORTANT: Make sure that all equipment is turned off before
making any connections.
For speaker connections, use a minimum #16-gauge speaker wire with
polarity coding.The side of the wire with a ridge or other coding is usually
considered positive polarity (i.e., +).
NOTE: If you are unsure about the proper wire to use, consult your local
Infinity dealer about speaker wire and connection options.
The speakers have coded terminals that accept a variety of wire
connectors. Figure 5 shows the most common connection.

2Insert bare end;

Figure 5. This example shows how to connect bare wires to the terminals.
To ensure proper polarity, connect each + terminal on the back of the
amplifier or receiver to the respective + (red) terminal on each speaker, as
shown in Figure 6. Connect the – (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier, receiver
and television to confirm connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +)
when making connections. Doing so will cause poor imaging and
diminished bass response.

Figure 7. For RC263, R263, and R253 speakers, you can choose either set of terminals.
IMPORTANT: Do not remove the metal jumpers from between the
two sets of terminals when connecting the speaker wires.
BI-WIRE CONNECTION - RC263, R253 AND R26 3
These speaker connection assemblies have two sets of input terminals
that are connected by metal jumper bars. The upper set of terminals
is for the midrange/tweeter, and the lower set of terminals is for the
woofers. This arrangement allows you to bi-wire the speakers using a
single stereo amplifier or using two stereo amplifiers. Bi-wiring can offer
sonic advantages and more flexibility in power-amplifier selection over
a conventional single-wire connection. Before bi-wiring the speakers,
remove the jumper bars.

For more information about various speaker-wire and connection
options, contact your local Infinity dealer.

FINAL ADJUSTMENT
Check the speakers for playback, first by setting the system volume
control to a minimum level and then by applying power to your audio
system. Play a favorite music or video segment, and increase the system
volume control to a comfortable level.
NOTE: You should hear balanced audio reproduction across the entire
frequency spectrum, from high tones to deep bass. If not, check all
wiring connections or consult the authorized Infinity dealer from whom
you purchased the system.
A number of different factors – including the room’s size and shape,
the construction materials used to build the room, the listener’s
position relative to the speakers, and the position of the speakers in the
room – will affect the amount of bass you hear and the stereo-image
quality (the placement of sounds in space). Listen to a variety of music
selections and note the bass level. If there is too much bass, move the
speakers away from nearby walls. Conversely, if you place the speakers
closer to the walls, you should hear more bass.
Nearby reflecting surfaces can adversely affect stereo-imaging
quality. If they do, try angling the speakers slightly inward toward the
listening position until you achieve the best possible sound.
CARE OF YOUR SPEAKER SYSTEM
Each Reference series cabinet has a wood-grain vinyl finish that does not
require any routine maintenance.You may use a soft cloth to remove
any fingerprints or dust. Clean the grille by gentle vacuuming.
NOTE: Do not use any cleaning products or polishes on the cabinet
or grille.
If your Infinity speaker needs service, contact your Infinity dealer or
distributor, or visit www.infinityspeakers.com for the location of the
nearest service center.
