As an extra sanity check, make a noise floor meaurement, i.e. one where no sound is made. See what that gives you. You might also try taking measurements of the speaker in way-off states, like muffled by a pillow, through a small value cap that tips up the response, etc. See if you can see those kinds of large changes.
