I believe that volume 70 is 0dB attenuation, leading a 0dBFS signal drive the phantom to its full volume SPL wise.
There is roughly 3dB difference between each model, so it is not surprising that to reach a given loudness, necessary for a comparison, you need to crank the non gold higher.
As for the difference in terms of mids, I think we shall not forget that the quality of basses and highs are also affecting how we perceive mids.
I also don’t know exactly what is the transition frequency between the mid range driver and the tweeter, but I would suspect that what is perceive as mids is served by the combination of those two drivers, giving an other explanation why we perceive a difference in that register.
