It is possible that the left channel is actually 3dB louder than the right channel. The target is definitely better matched to the measurement now.
Good point - I automatically assumed that the channel levels were aligned, but it is possible they are not.
Though I don't believe it could be due to the measurement location; if the level mismatch was acoustic the subwoofer would still be equally loud between channels (since it is mono).
The channel balance control could introduce an overall level imbalance that impacts the sub as well, however.

Hmm yes, subwoofer should be the same for both.
 
The Raw-L and Raw-R levels look different to the levels in the Left and Right channel measurements. There is only about a 1dB difference between them in the evaluation but the left channel is 3dB higher in the measurements. Are you measuring directly on the centre line between the speakers?
Yes, center line pointing between them at ear level height.
 
@WiiM Team @jiaxin.li (WiiM) Can you perhaps explain why the vertical scale is shifted/misaligned by about 3dB between the two channels (RoomFit measured response in post #35)?

@lempogi To me this looks much better than before.
The vertical scale of the two channels is misaligned, that is true, but if we look at the part of the response <50Hz (where the signal is mono with a single sub) we see that the difference in level between the target and the measured response is practically the same in both channels.
So in practice I'd say this correction should be OK. By the way, which correction frequency range did you use for this latest attempt?

We also see that the overall target level is set much more reasonably than it was, previously it was about 5dB too high, e.g. here:
I see, thanks! I used the 90Hz crossover and 10ms delay setting with 20-400Hz range like before.
May I know if this is better than the one we did before with 20-8kHz range of measurement instead?

This latest one looks a little better to me, yes. But I suspect it is not a night and day difference audibly. :)
Hope you're enjoying it!

Note that the "Predicted" curve (and the "Target" curve) are not vertically centred between "Raw" and "Equalisation", as one would expect.

I'm tempted to hope that the error is rather with the display of the predicted and target curve, not with one channel being actually louder. The evaluation results seem to point into this direction.

Thank you! Yeah, I have not yet listened long enough to compare the two, but I didn't notice any big difference so far. For sure I am enjoying it, also my wife and kids too! They appreciate the benefits of room correction now.

Would you expect the target curve to be centred between Raw and Equalisation? That would only be true if the target was 0dB. In this image you can see the peak of the Raw is about +16dB and the Equalisation is about -11dB. The target/predicted is equal to the sum 16-11=5dB.

Is this really a discrepancy?

But yes, I made it sound like this was a clear hint at (just) the display being wrong, which is it not. The readings of the right channel taken for themselves are consistent. It's the evaluation screen that makes the left channel readings look strange.

Yup the evaluation screen shows different raw levels compared to the measurements.
