Your in room response should tilt slightly downward to the right. However your in room picture should not. :p

Looking pretty good to me in either case.

Thanks for the Feedback, do i understand you right - there is too much volume in 10-20`000 Hz ?

From 80db at 20hz to 69db at 20khz, I think there already is a downward tilt. It's just the scale of his graph is too tight so that it looks too flat.

Sorry, I was making a little joke.

You appear to have just about the right amount of tilt to the response. The scale makes it hard to see, but it is there. Around 10 or 11 db from low frequencies to high which is pretty much spot on.

When I viewed the picture of your room, the picture is tilted slightly down to the right. Which is my joke comment. FR should tilt right not the room.

Beautiful listening room you have. Are those quadratic diffusers in the corners?

Yes, GIK has Bass Traps Tuned to your needs, in my case i ordered 3 Traps for my Room Modes at 40 Hz and 3 at 70Hz. They delivered big time !

Hi Chromatischism
I am sorry, i have to search how to do this...
Go to the upper left area of the graph area and click the plus sign once or twice. If the frequency response line is not centered, go to the upper right of the screen and click on scrollbars. Then you can center the graph.

The spectrogram would also be interesting to look at. You could just post the whole .rew file and we could take a closer look at the entire information set. Also would be good to see how you have the microphone positioned when you take the measurement.

Actually, in the upper right corner of the graph is the icon where you input the desired X and Y range.
