1) Sure, flat response is ideal. But as what expense to GET flat F-R? Meaning what other things are being lost in that process? Are they more important or less? Depends on what you value the most.
2) I made the unpleasant discovery that tweaking my speakers made a singer sound flat, sharp, or even not like the same person! And with no reference to go by, which one was correct?
3) Flat speaker response may not correlate to flat in-room response. The solution of course is to get Genelec’s speaker which, at the press of a button, eq’s the speaker so that in-room response is flat. And if that is so great, why isn’t anyone other than recording engineers buying it.
4) Then there is the debate about what is "flat"? Thiel speakers have "flat" treble but for many people that is unlistenably bright.

Every track you play requires its own curve. But nobody has yet invented a system which can store a different EQ preset for every track.
A good lesson to learn. I got a DEQ to fix in-room FR. Having that kind of power became a horrible compulsion to EQ every song so it sounded "right".
