Safe Limits of Operation
Polk Audio 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 W (per channel). It is important to understand
what those numbers mean when choosing a receiver or ampli-
fier 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 a higher power rating.
Automobile horsepower is a good analogy. Your car probably
has far more horsepower than it needs for your daily commute
and is likely capable of going well over 120mph (190km/hr).
Having that extra power is good for on-ramp acceleration
and danger avoidance (like getting away from brain-eating
zombies) but that doesn't mean that it is advisable to operate
your car on North American highways at full power and maxi-
mum speed for an extended period of time. Just ask your local
state trooper if you are in doubt. 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 ampli-
fier, 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.

Bring On The Noize!
Please inspect each loudspeaker carefully. Notify your
Polk Audio dealer if you notice any damage or missing items.
Keep the carton and packing material. They will do the best
job of protecting your speakers if they need to be transported.
