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 importantto understand what those numbers mean when choosing a receiver or amplifier for your Polk loudspeakers. The lower number indicates the lowest continuousrated 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-ratedamplifiers 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 highwaysat full power and maximum speed for an extendedperiod 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 stronglyurge 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

WARNING: LISTEN CAREFULLY
