11. Grounding or Polarization. This product is equipped with polarized alternating-
current line plugs (plugs having one blade wider than the other). This plug will fit into
the power outlet only one way. This is a safety feature. If you are unable to insert
the plug fully into the outlet, try reversing the plug. If the plug should still fail to fit,
contact your electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the polarized plug.

Safe Limits of Operation
Polk specifies the recommended amplification range for each of its passive
(non-amplified) loudspeakers. Typically that specification will be expressed
as a range of power such as 20-200 Watts (per channel). It is important to
understand what those numbers mean when choosing a receiver or amplifier
for your Polk loudspeakers. The lower number indicates the lowest continuous
rated power that will yield acceptable performance in a typical listening environment.
The higher number indicates the highest per channel power that should be used
with your Polk speakers. That number should not be confused with a “Power
Handling” specification, and it does not imply that the speaker will safely handle
that full amount of power on a long-term basis. We specify a wide range of power
ratings because not all electronics manufacturers use the same method for rating
power. In fact, high quality lower-rated amplifiers sound better and play louder
than low quality units with higher power rating.
Similarly, we recommend using amplifiers and receivers with rated power above
the Power Handling limits of our speakers because having extra power available
for short term peaks is conducive to better sound quality, maximum dynamic
range and effortless high volume output. But we strongly urge you not
to use the full power of your amplifier or receiver for daily listening.
Loudspeakers can be damaged when an amplifier, regardless of its wattage,
is made to play at higher listening levels than its power can clearly produce.
Operation at this level can result in very high levels of audible distortion originating
in the amplifier, which can add a harsh, gritty sound to your listening material.
If you hear distortion—turn the volume down or risk damaging your speakers.
You can damage just about any speaker, regardless of power rating,
if you drive an amplifier to or beyond the point of distortion.
