Have you tried crossing the axis in front of you?
Again, you're looking at measurements that have no relevance to small room acoustics. Sorry to be blunt, but there's no point in looking at measurements you don't understand.
Echo that. Measure each driver from each speaker with a short window in REW.You need to measure first the speakers invidually both with and without the panels. And then compare left and right, both with and without panels. That's two different comparisons. I'm not sure what you're showing.
You can't measure speakers simultaneously FIY.
Naive question, but did you try to swap the speakers L<>R?
But that will also change the level.Or just pull the right speaker closer to you, an inch or two at a time.
Easy "timing" experiment.
What is wrong with just balancing out the levels with either a balance control or DSP to center the image?

OK, understood, good luck.... room issues can be frustrating.That's what I'm doing in the mean time, but it doesn't really give satisfactory results. Sure, I can center vocals that way, and that helps, but imaging is still unclear depending on content and it's easy to notice that there is more "ambience" coming from the left than from the right. It just feels wrong, which is why I'm trying to address the root cause if possible.
I think adjusting the channel balance is an acceptable solution for fine adjustments to correct a subtle imbalance, say 1 dB or so. When faced with a massive 4 dB problem, it's just papering over the misery.
That's exactly what I was going to suggest when started reading the thread. Not only I have asymmetric setup but also slight but infamous parasound/alps imbalance and dirac helped to mitigate itI've read claims that time based room eqs (vs peq approaches) can help stabilize image wander due to asymetrical layout. Its worth a shot though in your near field case I imagine it might only help over a very tight listening space. Does dirac offer a limited trial, to check the concept?
I just received the large slab of 4"-thick acoustic foam I ordered.
Disappointingly, the ETC shows little difference compared to the thinner wedges. In fact, the wedges seem slightly more effective, likely because I can cover more surface area with them.
I did some more listening tests with the foam wedges and after fixing the slightly imbalanced speaker pair. The imbalance has now been reduced to just 1.5 dB, which I think I'm gonna have to accept and move on. That's before EQ; I plan to re-EQ this weekend, there's a good chance the remaining 1.5 dB might go away after EQ simply because the left-right responses will be aligned over the bottom half of the spectrum. We'll see.
The imaging seems to have improved too, but I can't really quantify that so it might just be placebo for all I know.
