PLACEMENT
For front-channel use, place one speaker on the left and another on the
right, along either side of the television monitor. Since the speakers are
magnetically shielded, you can place them near the TV without worrying
about the magnetic field distorting the TV picture.
Stereo
Before deciding where to place your Cascade speakers, survey your room
and think about placement, keeping the following points in mind and
using Figure 1 as a guide:
For surround-channel use, place speakers on bookshelves or stands
alongside the listening position. Final placement depends on room
acoustics, availability of space and your listening preference
(Figures 2 and 3).
• For best results, place the speakers 6' – 8' (1.5m – 2.5m) apart.
• 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.
In 6- or 7-channel configurations, place the rear channel(s) behind the
listening position, as shown in Figures 2 and 3.
• Refer to“Home Theater”if you also plan to use the speakers for home
theater reproduction.
NOTE: An Infinity powered subwoofer will add impact and realism to both
music and film soundtracks. Contact your Infinity dealer for recommenda-
tions on subwoofer models for your application.

stand, making
sure the aligning
posts are lined up
with the receiver
terminal cup.
1. Open spike kit and locate the following items: feet (with spike/round
ends), four locking nuts, four nylon domes and one wrench.
2. Lay each stand on its side and locate the four threaded holes on the
bottom of the base.
3. For carpets, screw the round end of a foot into each hole and fully hand-
tighten a nut onto each one. For hard-surface floors, screw the spike end
into each hole instead and leave the rounded end exposed.
4. Carefully flip each base upright to sit on its feet.
5. If needed, adjust the feet so each speaker is level and then tighten each
nut with the enclosed wrench.To protect hard surfaces (e.g., wood floors),
slip a nylon dome onto each round end.
3. Insert #8 pan-
head screw into
rear of speaker to
secure to stand.

Attaching the Grilles
WALL-MOUNTING
The Cascade loudspeakers use a unique frameless grille. Each end of the
grille cloth contains a magnet. Simply curl the magnet assembly behind
the grille cloth, place one end of the grille just above the tweeter and
then gently pull the grille taut, attaching the other end of the grille just
below the woofer.
NOTE: The customer is 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.

WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any
connections.
For speaker connections, use a high-quality 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 desired, consult your local Infinity dealer about speaker wire and
connection options.
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 4. Connect the (black) terminals in a similar way.
See the owner’s guides that were included with your amplifier or 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 5.This example shows how to connect bare wires to the
terminals. Banana plugs may also be inserted directly into the rear
of the connector.
Figure 4.This figure shows how to connect bare wires to the terminals.

of a stereo or home theater system.

FINAL ADJUSTMENTS
BI-WIRING
Check the speakers for playback, first by setting the system volume con-
trol to a minimum level, and then by turning on the power of your audio
system. Play a favorite music or video segment and increase the system
volume control to a comfortable level.
The outer connection panel and internal dividing network of the Cascade
loudspeakers are designed so that separate sets of speaker cables can
be attached to the low-frequency transducer and midrange/high-
frequency transducer portions of this dividing network.This is called
bi-wiring. Bi-wiring can provide several sonic advantages and
considerably more flexibility in power amplifier selection.
NOTE: You should hear balanced audio reproduction across the entire
frequency spectrum. If not, check all wiring connections or consult
the authorized Infinity dealer from whom you purchased the system.
The amount of bass you hear and the stereo-image quality will be affected
by 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.
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, there will be more bass output.
Nearby reflecting surfaces can adversely affect stereo-imaging quality. If
this happens, try angling the speakers slightly inward toward the listening
position until the optimum effect is achieved.
CARE OF YOUR SPEAKER SYSTEM
Each Cascade Series enclosure has a finish that does not require any
routine maintenance.When needed, use a soft cloth to remove any finger-
prints or dust from the enclosure.
Figure 7.
NOTE: Do not use any cleaning products or polishes on the cabinet
or grille.
Single-Stereo Amplifier
If a problem occurs, make sure that all connections are properly made
and clean. If a problem exists in one loudspeaker, reverse the connection
wires to the left and right system. If the problem remains in the same
speaker, then the fault is with the loudspeaker. If the problem appears in
the opposite speaker, the cause is in another component or cable. In the
event that your subwoofer ever needs service, contact your local Infinity
center near you.
IMPORTANT: Please attach your sales receipt to this manual and store it
in a safe place. In the event that your Infinity speaker requires warranty
service, you will need to provide your sales receipt.
