The primary purpose of monitors is to bring as much clarity as possible to each and every frequency in the audio mix and give the mixer concise knowledge of what is in the sound...piece by piece. So that mixer can make informed decisions regarding composition, eq'ing etc.

A secondary purpose of audio monitors is to represent the real world sound. I used to record at a studio here in town with 3 studios, a mixing room and a mastering suite. In the mixing room were 4 speakers. I was told that 2 of the speakers cost 6K and the other two cost 1K (Yamahas). The engineer explained that when he was really digging into the song and "splitting hairs," he would listen to the 6ks. When he was finishing up and wanted to hear more of a real world sound, "random car" sound, he would flip a switch to the Yamahas and make adjustments before calling it done. As I sat and looked on, he went back and forth several times.
