PLACEMENT RECOMMENDATIONS

FOR LSi SERIES FLOORSTANDING LOUDSPEAKERS

One LSi Floorstanding speaker is the “left” channel speaker, and the other is the “right” channel speaker. The serial number label identifies which speaker is which [figure 1]. The “left” speaker should be placed on the left side of the room as you face the front of the room. To get the most realistic stereo image and lifelike sound, place the speakers so that an equilateral triangle is created between the speakers and your favorite listening position [figure 2]. Your LSi Series Loudspeakers are magnetically shielded for safe placement near your TV or video monitor. If you notice video distortion or discoloration, immediately move the speakers away from the TV and call Polk Audio Customer Service Monday – Friday, 9:00 AM – 6:00 PM Eastern Time, (800) 377-7655 (USA and Canada) or email polkcs@polkaudio.com. If your room arrangement forces you to place the speakers farther apart than the distance from which you are listening, angle the speakers toward the middle in order to support a more solid center image. Rubber feet and adjustable carpet spikes are included to provide stability on any type of floor. To install them, lay the speaker carefully on its side and screw in the spikes as far as they will go into the threaded inserts in the base of the speaker. For wood or tile floors, slip a rubber foot over each spike. For carpeted floors, use bare spikes [figure 3]. You will achieve optimum performance when the speaker is level and stable in all directions.

CONNECTION OPTIONS FOR LSi SERIES FLOORSTANDING LOUDSPEAKERS

Follow the hookup directions included with your receiver. Strip 1/2 inch (12.7mm) of insulation from each of the two conductors of the speaker wire to expose the bare metal and twist each of the individual conductors into single unfrayed strands. Note that one of the terminals on the rear of each speaker is red (+) and the other is black (-). Make certain that you connect the wire from the red (+) terminal of your amplifier or receiver to the red (+) terminal on your speaker and the wire from the black (-) terminal of your amplifier or receiver to the black (-) terminal on your speaker. Most wire has some indicator (such as color-coding, ribbing or writing) on one of the two conductors to help you maintain consistency.

To connect wire to the binding post [figure 4], unscrew the hex nut and insert the bare wire into the hole near the base of the binding post. Do not insert the insulated part of the wire into the hole as this will not give you a good connection. Twist the hex nut back down the binding post until it firmly meets the wire. Do not over tighten.

At the heart of the LSi25 is its advanced driver design.
