POLK/MOMO: CHAMPIONSHIP PERFORMANCE
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 chan-
nel 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.
Polk Audio’s Customer Service Department is available from 9am—6pm, EST, Monday
through Friday, at 800-377-7655 (US & Can only, outside the US call 410-358-3600).
Please do not hesitate to call us if you have questions about your speaker system. We
positively love this stuff.
You will find additional information, informative articles, manual updates and cool stuff

Safe Limits Of Operation
Your Polk/MOMO Subwoofer is made with the highest quality materials for years of trouble-
free performance. However, damage to loudspeakers can occur when an amplifier, regard-
less of its wattage, is made to play at higher listening levels than its power can clearly pro-
duce (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.
Hear distortion? Turn it down. Contact Polk Customer Service 800-377-7655 (9am—6pm,
EST, Monday through Friday).
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.
