ENGLISH

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” specifi- cation 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.

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.

PLACEMENT OPTIONS

Polk Audio MC Series Loudspeakers

give you nearly endless placement options. But remember, where you locate in-wall speakers bears careful consideration,

as installation requires that you cut a hole in your wall!

Fill a room with sound by installing speakers in nearly any wall or ceiling location (figure 1). Polk MC Series Loudspeakers have a wide dispersion pattern and aimable tweeters that allow you to focus their sound.

ADJUSTING THE TWEETERS

Aiming the tweeters toward your listening position improves imaging and detail. When using MC Series Loudspeakers as front/main home theater speakers (figure 2), aim the tweeters toward your listening position. For rear/surround speakers installed in walls or ceilings (figure 3), aim the tweeter toward the nearest reflecting surface (an adjacent wall or ceiling) for a more diffuse sound field. For a more direct sound, aim the tweeters at your listening position. (See figures 4 & 5 for aiming

the tweeter.)

Loudspeakers can be damaged when an amplifier, regard- less 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 vol- ume 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.
