english safe limits of operation Polk 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 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 a higher power rating. 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. bring the noize! Please inspect each loudspeaker carefully. Notify your Polk 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. building a home for your subwoofer- DXi sub enclosure 101 To get the best performance from your DXi Subwoofers, you must use a Subwoofer Enclosure. Don't bother using them in "free air," with no sub box, just popped into the back deck of your car. You will not get very good performance from your subwoofers if you do this. They are not designed to be installed infinite baffle or "free air." This will void the warranty. You can build your own box, buy a pre-built box or a box kit, or have your Polk dealer design and build a custom sub enclosure for you. Your DXi Subwoofers were designed to work well in a wide variety of enclosure sizes and configurations. more information @ www.polkaudio.com 1
