You supply a speaker with an audio signal. Your speaker converts the signal to a sound wave.
There is a loss invovled in this process. If you supply 100 watts to a speaker, some of it will become heat due to ohmic loss of the coil and friction between materials. This loss will not become sound waves.
If you put 100 watts of power and 5% becomes loss, then your speaker is said to have 95% effeciency.
Effeciency has nothing to do with distortion by the way....

Check out Bose, efficiency is the relationship of the output to size. You don't need Altec Lansing "Voice of the Theater" speakers to get a great sound. Look at Boston Acoustics and Polk Audio also, very efficient speakers without taking up all your room.

Producing the clearest, loudest sound while using the least amount of power
