* About Power Ratings

When making comparisons between product specifications it helps to understand what they mean, particularly with amplifier power ratings. The Federal Trade Commission has recently issued new regulations regarding the power ratings of all amplifiers including self-powered speakers. Polk Audio supports this effort to standardize power testing methods in order to provide consumers with a “level playing field” basis for comparison. Make sure the basis for the power rating is clearly stated before comparing it to another product’s specification.

The FTC rating is based on the continuous power output of the amplifier. However, music and movies are not continuous but are mainly composed of short bursts of sound. For this reason we also supply a “Dynamic Power” rating which measures the ability of the amplifier to produce power in short bursts similar to those found in music and movies. In our experience an amplifier with higher Dynamic Power output will play louder under most condi- tions regardless of the continuous power rating. Dynamic Power is typically greater than continuous average power although it is not uncommon for two amplifiers with identical FTC “Continuous Average” ratings to have very different Dynamic Power performance.

However, loudspeaker efficiency is by far the most important factor in determining how loud your system will play. Loudspeaker efficiency is usually given as the amount of sound produced by 1 watt at a distance of 1 meter. A medium efficiency loudspeaker rating would be around 87 dB from 1 watt at 1 meter. A highly efficient loud- speaker might be 90 dB. Each 3dB increase in efficiency doubles the sound output for a given power input. So

a 100 watt, 90 dB self-powered speaker and a 200 watt 87 dB unit would produce the same sound output. For this reason we also specify the loudspeaker efficiency and calculated maximum sound output.

Polk Audio and the Consumer Electronics Manufacturer‘s Association are currently engaged in an effort to set standards for specifying the actual acoustic output of self-powered speakers. If we are successful, consumers will be able to use these ratings to make more meaningful product comparisons and better purchasing decisions
