PLACEMENT RECOMMENDATIONS
FOR THE CSi SERIES CENTER CHANNEL LOUDSPEAKER
The CSi Series Center Channel Loudspeaker incorporates the most effective magnetic shielding
available so it can be placed safely on or near your TV or video monitor. If you notice video
distortion or discoloration, immediately move the speaker away from the TV and call Polk Audio
Customer Service 800-377-7655 (9
AM to 6PM EST, US or Canada) or polkcs@polkaudio.com. The
most popular placement for a center channel speaker is on top of your TV, anchoring the dialogue
and effects to the screen [figure 1]. An alternate placement is on a shelf below your TV [figure
1]. If you are using a front projection TV system, place the center channel speaker on a small
stand or table immediately below the bottom of the projection screen, or at ear level behind the
screen if your screen is acoustically transparent. Consult the owner’s manual for your screen.
Adhesive rubber feet are included with your CSi Center Channel Loudspeaker and may be
attached to the bottom of the speaker to protect your furniture and keep the speaker in place.
PROCESSOR MODE CONFIGURATION
FOR THE CSi SERIES CENTER CHANNEL LOUDSPEAKER
The “bass management” or “speaker configuration” menus of most surround receivers offer the
choice of “normal” or “wide” modes for center channel operation. In discrete channel digital
processors these modes are referred to as “small” and “large.” Normal (small) mode filters bass
frequencies from the center channel speaker and sends them instead to the front left & right main
speakers or to the subwoofer output (LFE) jack. Wide (large) mode sends an unfiltered, full range
signal to the center channel speaker. Use the Small (normal) mode for optimum center (and
surround) channel performance and reliability.
PLACEMENT AND BI-POLE/DI-POLE OPERATION
OF FXi SERIES SURROUND FX LOUDSPEAKERS
The FXi Series Surround FX Loudspeakers were designed to provide the ultimate diffuse sound field
experience in your home theater system. One FXi speaker is the “left” channel speaker, and
the other is the “right” channel speaker. The serial number label identifies which speaker is
which [figure 2]. The “left” surround speaker should be placed on the left side of the room as you
face the front of the room. The type of surround processor you use will influence your placement
and bi-pole/di-pole switching choices [figure 2]. Experiment to find the right balance of sound
quality and room integration:
Direct surround effects—bi-pole mode [figure 3a & 3b]: If you plan on placing the speakers
more than one foot (30cm) behind the primary listening position we recommend using the “bipole”
switch setting [figure 2] and placement.
