Speakers (Sound Detailed study) frequency response curves

[PB]

Hey guys,
For Speakers/Headphones, should the frequency response curve be as flat as possible to emulate the studio recording as closely as possible or should it peak a little at the lower and higher frequecies  (seeing as humans tend to have less sesitivity at those ranges).
Regards,
PB
p.s Thanks! I am getting conflicting info, with txtbks saying it should be as flat as possible and some questions saying it should be peaking at the lower and higher frequencies

Personally I've only been told about flat response curves and to not worry about sensitivity in this case.

Ah i see, thanks
