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 (9AM 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.
