Sensitivity and efficiency are more or less the same thing. Sensitivity is dB output relative to voltage or power input. Efficiency is the conversion of electrical to acoustical power expressed as a percentage. Sensitivity is usually used with respect to the end result of driver plus enclosure, efficiency with respect to the raw driver. The only modeling program I'm aware of that shows both sensitivity and efficiency of the driver in an enclosure is HornResp. With HornResp you can compare sensitivity and efficiency of a horn and an OB. The sensitivity and efficiency of the OB pales in comparison to the horn.
FWIW a horn with 107dB/watt sensitivity will average about 40% efficiency. An OB with 92dB/watt sensitivity will average about 2% efficiency.
