I'll try that later
I just dont understand what could have changed the right channel so much since the last room calibration, cause the room is exactly the same.
How to think about room correction settings like frequency range and gain?

Microphone position?
Same listening position, nothing has changed. For now I'll just go back to the old one I did before the calibration file. The new one just sounded terrible. Like Beats headphones filling the room...

Since microphones normally roll off at low frequencies I would expect less bass when using the calibration file since the measured response will need less boost or more attenuation to reach the target. Can you show screenshots of room correction measurements with and without the calibration file?
I did try it again now calibrated and uncalibrated and the difference seem very small
Calibrated
Not calibrated
Old one not calibrated (four weeks ago) that sound the best to me
Absolutely nothing has changed to explain the difference from then to now. The differences in the left speaker is way more subtle.

Did you reduce the the maximum volume by changing the volume limit in "Audio Settings"? This prevents clipping caused by the boost applied by room correction. If you don't you may get distortion and the boost is higher in the two recent measurements making distortion more likely. There is a thread discussing how to determine the required volume limit using REW.
No changes what so ever. Very strange indeed.

You should reduce the volume limit though.
Hi
I cant find that thread and this is way above my head. Do you mean I should reduce the volume limit just during the room correction process? I feel completely lost here.
But I never reduced volume before either so if this is the reason wouldn't the boost be there in the previous measurement also? Sorry for all my questions but this is getting way to complicated for me sorry.
What should I set the volume limit to?

Reduce the volume limit after the room correction process.
Quick question - when doing room correction in Wiim, what is the optimal volume to set on the device controlling the volume in the room. In my case, my Wiim Ultra is set to max fixed volume and connected to my amp where I control the volume to the speakers/sub. Are there any instructions as to how to get the best room correction observations (I'm using iPhone w/ a Dayton Audio iMM-6C along with the downloaded calibration file.) Room is an apartment living room. I do have a db meter to set the volume specifically if I wanted to. Thanks!
Iv'e just assumed your normal listening level setting would be optimal. But this is a great question for the experts out there.
There are no hard and sound instructions on the volume. You might go by these guidelines:
- The higher the level, the better the signal-to-noise ratio of the measurement, so higher is generally better.
- If you here furniture rattling during the swipe, reduce the level. RC cannot compensate for such non-linear defects.
- Don't use a level that feels uncomfortable to you, don't go over the top.
