Since you have summarised your points nicely here are my points, firstly thanks for highlighting the gist of your original comments, now for my comments,There is no live acoustic equivalent for loud orchestra performance that is being played back softly on a reproduction rig, i.e. attenuation is unique to reproduction systems, and you have correctly observed, a recording sounds most natural when played back closest to the dB level of the original recording, all things being equal, i.e. no compression etc.
As to the crux of your post, the loudness curves run counter to your main point, if a loudspeaker is linear from top to bottom in respective of it's frequency response and radiation pattern given linear attenuation, the bass will the first to fall off the radar, when I looked this up, it was even more interesting, at soft volumes, the ear is even more discriminatory against bass frequencies in favour of the upper midrange frequencies, so linear attenuation is undesirable as it would sound less natural, which runs counter to your point.
Secondly, many (not all) full range planars e.g Numerous Apogees, Magnepans, Quads, Audiostatics fall into this category suffer from panel resonance , Ironically the will help their behaviour at softer levels since the increased ouput around resonance point will compensate for the ear reduced sensitivities at the frequencies. Furthermore, the measured response of the some of the conventional speakers (that I am aware of) that sound best at soft volumes show a boost in the lower frequencies.
