The X-curve target does not deliver the neutral direct sound it was believed to

Evidence

But the reality is that when the X-curve was decided on in the 1970s it was not thought of as being idiosyncratic. It was believed to be the steady-state room curve necessary for mixers in dubbing stages and audiences in cinemas to hear a neutral, flattish, direct sound. Subsequent events have shown that this is not the case. — , Toole, Floyd E - Sound reproduction-…, 1222
