Power is expressed in watts and describes the actual intensity that can be heard from the speaker. Your number indicates the maximum power that the speaker can handle for an extended period of time.

The frequency response indicates the range of tones that a speaker can produce. The lower number indicates how low the speaker can play and how deep its bass goes. The higher number indicates the upper limit of the speaker's tonal range (high frequencies).

The sensitivity of a speaker describes how effectively power (watt) is converted into sound pressure level (dB). Therefore, the higher the value, the louder the speakers will play with a given power.
