[. . . ] 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. [. . . ] Run separate speaker wires to the low and high frequency drivers from a single amplifier: after removing the jumpers, connect one set of speaker wires to the upper terminals on each speaker and one set of (usually heavier gauge) wires to the lower terminals. Connect the other ends of both wire sets to the corresponding amplifier outputs. Bi-wiring, or using separate speaker wire connections for high and low frequency sections. To use Banana Plugs (US only): Unscrew the binding post lug nuts completely to expose the binding post plugs (plastic plugs inserted into the binding posts). Bi-amping [figure 9] allows you to use separate amplifiers for the high and low frequency sections of your loudspeaker for greater dynamic range and lower distortion. After removing the jumpers, connect the speaker wires from the high frequency amplifier outputs to the upper set of terminal posts on each speaker. Follow the same procedure for connecting the low frequency amplifier outputs to the lower set of terminals. Remember to maintain correct wiring polarity (+ to +, - to -) in all connections. Wall mounting requires basic skills in with tools such as a drill and a screwdriver. If you are in doubt that you possess the necessary skills or tools, consult your Polk Audio dealer, or a professional installer. ⷠMake sure the material on which you plan to mount the speakers (plaster, drywall, paneling, stone, etc. Make sure the locations you select do not conceal electrical wiring or plumbing.

" · If you are certain that there is a stud behind the wall surface, drive a #10 screw (not included) through the wall and into the stud [figure 11a]. ⷠIf there is no stud behind the wall at the chosen location, install a #10 wall anchor (not supplied) into the wall by following the wall-anchor-manufacturer's instructions [figure 11b]. ⷠFor masonry walls, use a masonry drill bit and #10 masonry anchor and screw (not included). ⷠTighten screws into stud or wall anchors, leaving screw heads protruding 1/16" (1. Your Polk loudspeakers are made with the highest quality materials for years of troublefree performance. However, damage to loudspeakers can occur when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce (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, that can add a harsh, gritty sound to music. 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.
