Connecting Your Polk/MOMO Subwoofers 5-way binding post connectors are located on the back of the subwoofer. For a bare wire connection, strip 1/2 inch (12. 7mm) of insulation from each of the two conductors of your wire to expose the bare metal and twist each of the conductors into a single unfrayed strand (so you have two unfrayed strands). Note that one of the terminals on the woofer is red (+) and the other is black (-). [. . . ] 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, which adds a harsh, gritty sound to the 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 than from a high-powered one.

Low Frequency Cut-Off For Mid-Range Speakers In Systems With Subwoofers Now that you have a subwoofer in your system, you may want to decrease the amount of bass going to your mid-range speakers. This will get you better mid-range sound and increase the power handling. There are two ways to roll off the bass before it gets to your mid-range speakers. One way is to use a "bass blocker, " a capacitor placed in series with the speaker input. Bass blockers are installed in series, one end connected with the positive lead from your amplifier and the other end connected to the positive lead of each of your speakers. Bass blocker capacitors (200 microfarad @ 100volts, non-polarized) are available at any RadioShack or parts supply house. The other route is to use an electronic crossover device that allows filtering below 100Hz or so. Find these devices at your authorized Polk Audio dealer. Tech Assistance Or Service--Not Hearing Anything?Read This: If, after following these hookup and installation directions, you experience difficulty, please double-check all wire connections. Make certain your electronic equipment is operating correctly by hooking up another speaker to the speaker output. For example, if you are not getting sound from the left channel speaker, connect the right channel speaker to the left output. If you still get no sound from that side, the problem is in your amp or source electronics. Should you isolate the problem to the speaker, contact the authorized Polk Audio dealer where you bought your speakers. Authorized Polk Audio dealers are the best source for advice and assistance.
