John is right, unless stated otherwise sensitivity is supposed to be measured at 4 Pi (360 degrees) anechoic. It is common to see speakers designed to be mounted on or in walls labeled to be measured at 2 Pi though.

Axiom's in room, just gives a better idea of real world performance, but all speakers get the same sort of boost.
