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.

1Loosen

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

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.
