You are right that sensitivity and efficiency are different but your definition of efficiency is wrong. Efficiency is how much sound energy is produced by the electrical energy provided to the speaker. Most of that energy is actually converted to heat (that's why voice coils melt) rather than sound. A speaker with a sensitivity of 90db is only 0.62% efficient - the rest of the energy goes up the chimney. A detailed discussion and the effects of efficiency can be found at on Ron Elliott's webpage.
