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 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. Simply put,
avoid excessive amplifier volume. 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. And always make}
sure the amplifier is turned off when you're connecting or
disconnecting cables.
