Many if not most people advise using the internal test tone generator method I just outlined as a starting point, but then tweaking the sound to taste. They are wrong. If your goal is high fidelity, which means high truthfulness to the balance of sound you would have experienced in the movie theater originally, as intended by the artists who made the movie, then you do this calibration once and then leave it alone unless you reconfigure your room or move the speakers.
If your goal is instead to gimmick the sound and alter it to what you find most pleasing, then by all means, tweak away and set anything to whatever values suit you.
In A/V reproduction accuracy, there IS no concept of "accounting for personal taste/preference". As art consumers we don't "pick" the level of bass, nor the tint/brightness of a scene's sky, any more than we pick the ending of a novel or Mona Lisa's type of smile. "High fidelity" means "high truthfulness", faithful to the original artist's intent: an unmodified, neutral, accurate copy of the original master, ideally being exact and with no discernable alterations, aka "transparency".
