You're right, there is some ambiguity because there is no accepted standard. Eminence measures in a chamber with the driver mounted to the baffle board and the microphone on-axis one meter from the baffle board. They then average response over the entire range. This means the rising response from collapsing DI and breakup modes are factored in. All-in-all, it is a pretty reliable indicator of overall sensitivity, but it does not take frequency range into account.
