superultramega,
No you are not confused. Efficient speakers are not going to have any advantage at low listening levels. There is 0 logic in that. If anything, they could be worse, as they will exacerbate any issues with distortion at low power levels. If you claim high efficiency speakers are better and need for an amp with better SQ at low volume levels, then you probably have not thought it through.
Flatter bass at lower frequencies may help w.r.t. the statements about equal loudness contours. Early bass roll-off is made worse at low levels. You may find some peaking of bass in your room response, which normally would be a negative, be turned into a positive. As pointed out, can't deny equal loudness contours.
