[. . . ] In either case, mount the speakers two to four feet (60-120cm) above your head (when seated). POWERED SUBWOOFER (Figures 4, 5) The RM6800 System includes a Powered Subwoofer to enhance bass and really add punch to your home theater. This subwoofer may be placed inside an entertainment center, behind furniture or next to a sofa or chair. It can be placed anywhere in the room, but you will get the best performance from it when it is on the same side of the room as the front satellites. [. . . ] Let the speaker slide straight down, allowing the screw head to slip behind the smaller end of the keyhole slot (Figure 7). If you require more flexibility, use an optional fully articulating "ball and socket" type mounting bracket such as the Series 25 RST by Omnimount, available at your Polk Audio dealer or in the Polk Webstore at www. Strip 1/4" (6mm) of insulation from each of the two conductors 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. If your speakers sound "thin, " with little bass and little or no center image, chances are that one of the speaker wires is connected backwards. Insert the bare wire into the hole and release the plastic tab (Figure 8). Repeat this step with the other connectors. a NOTE ABOUT BASS MANAGEMENT For best sound , DO NOT USE THE "SUBWOOFER OUTPUT" OR LFE JACK ON YOUR RECEIVER TO CONNECT THE SUBWOOFER. The RM6800 System features a powered subwoofer that has a built-in, adjustable low pass filter to separate the low frequency signals (the bass) from the full range signal. (This is usually beyond the "1 to 2 o'clock" position on the volume control. ) This results in very high levels of audible distortion originating in the amplifier, which adds a harsh, gritty sound to the music you're listening to. Contrary to popular belief, a speaker is more likely to be damaged by trying to get too much volume from a low-powered amp or receiver than from a high-powered one.
