What's a reasonable listening position response curve?

Taking room accoustics into account, what is an acceptable frequency response curve? What plus and minus dB is considered acceptable? Can you share yours.

There's the Bob Katz method flat to 1khz then linear diagonal to Nyquist which makes it about -7db 20khz. Some like a bit of bass boost but you need to watch your headroom. You could Google Harman curve for some info on that method.

Human beings can hear 0.1dB so the maximum tolerable variance is at most +/- 0.05dB, and I would go .01 just to be sure. Remember, sound quality is 110% entirely determined by frequency response. It is totally worth whatever EQ it takes to get this dialed in. EQ circuits do not alter sound in any way other than to make it perfect.

I agree a flat line response would be magnificent, but I doubt it's even achievable in a room. 

I'm interested in what others have been able to acheive and I'd love to see their graphs.

My feeling is that digital EQ is not even worth considering if you are serious about music and a graphic equlaizer is superior, although it generally only has 31 bands, so it's somewhat limited in what can be achieved.

Are you serious??

Um yeah. Your system should measure flat to within .01dB or it will be unlistenable. EQ does not alter sound except to make it perfect. I am totally serial.🙄

Is that the eye-roll? I can never figure out which one is the eye-roll.
