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 am-
plifier for your Polk Audio 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 Audio 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.

Automobile horsepower is a good analogy. Your car prob-
ably 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 advis-
able to operate your car on North American highways at full
power and maximum 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 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.
