Learsfool, "neutral", in almost all cases, is a subjective audiophile term. IMO, only people truly qualified to use this term are recording engineers who have the capability to compare their recordings with the live performance that was recorded in their studios or venue. Don't get me wrong, as I've sinned too using this term in the subjective sense for lack of a better word.
As for "midrange", this can cover 200-300 Hz to 1-3 kHz depending on the audiophile. And yes as you state, this covers most of the frequency range of most instruments. That's why most audiophiles often proclaim the midrange is the most important because most of the music occurs in this range. Broad yes, but sometimes useful.
