The power rating of a speaker only tells you how much power it can handle before damage. Its sensitivity rating tells you how loud it is. Sensitivity is a measure of efficiency, in that it tells you how much sound is produced at a specific drive voltage or power level. Typical sensitivity ratings are 93dB@1W/1M or 93dB@1M/2.83v. These examples are interpreted as meaning the speaker produces 93dB when measured one meter away given one watt or 2.83 volts, respectively.
