I know NS-10 boxes from my first studio experiences in the 80s. You somehow internalize the frequency response and you know that there are NS-10 in every studio, even semi-professionell ones. That makes it easy to compare the sound of your mix in several different studios. Nowadays there are many monitors available with a much better frequency response for less money, e.g. KRK or Behringer. But still many studios have NS-10 just for compatibility.
