The blue one looks loader. Have you looked at the phase, in particular t0?
Is there a guide you can link me to look at t0 ?

This is the current measurments of my speakers and they're pretty identical. I don't know what magic tricks you have up your sleeves but please share them because my experience has been completely the opposite (no effect on speaker balance after individual EQ).
Are you saying that despite these measurements, you still hear an imbalance?
May I ask what you used to take your measurements, which mic and software? In my honest opinion your after eq measurement looks great.
Starting from a very asymetrical configuration, the room as well as the left and right speaker that deviate from each other with differences up to 1.5 dB, I have once experimented a correction that completely centered the phantom image.
It was a separate left / right FIR correction generated by DRC according to a target curve calculated by Jean-Luc Ohl.
Here is a set of graphs provided by Ohl according to my measurements. I have removed the URL because the site is still in beta.

In the top left graph (C1), we can see that the left and right frequency responses (blue and red), measured from the listening position, are very different.
The FIR correction (minimum phase, 1024 taps) tried to correct this, aiming at the C8 curve (bottom right). I don't have a measurement of the result, which is not as accurate as the predicted curve, but the effect on the left / right balance was impressive !
I also learned some interesting things with these measurements and corrections. The bottom left prediction (C7) for separate left / right correction show that equalizing separately the left and right speaker below 200 Hz is useless. They must be equalized together.
Here, another setup (the same, but with my own parametric eq already applied before the measurement) show a very important problem between 90 and 108 Hz :

We can see that correcting both speakers at the same time (the above graphs are measurements of such a correction) doesn't work either because they are out of phase in this frequency range ! It can be heard from the listening position (although I rather had the impression that low frequencies were playing in one of my ears only), and if a recording has some drums panned on the left and right side, they sound way too loud.
The best solution was to eq the left and right channels together, except around 100 Hz, where the null was left uncorrected.
(I tried mono on pyhsical center, sound comes from empty space between C and R, it's really weird)
There a couple of thread in the REW forum, one is:Is there a guide you can link me to look at t0 ?

I do not how your REW setup is. If you have not done so yet, the it might be a good idea to measure the complete system with REW. You can record the REW sweeps as wav files and play them via a streamer or else while REW waits for the trigger signal to start syncing. So you could check the chain from the DAC upwards.
True. But I think how it is miked can make a difference. If the mikes are close (as they typically are in concert hall suspended setups), the violins are oriented in such a way that a lot of their directional (and reflected) sound ends up in the right channel. I hear it a lot in quartets as well as symphonic music.If you listen to a lot of Classical orchestral music, you should be aware that of the usual orchestra seating arrangement that puts violins on the left and tympani and "louder" or more dynamic instruments on the right. This can give the impression the the Right speaker is louder. This should go away if you downmix stereo to mono.
It could be I'm deafer in one ear I guess
I've used the balance control for my amp and am doing that for a few days after which I will centre it and see if any theoretical training effect is in play. If that doesn't work I'll go for the 180
Had the same thing happen to me. To be honest I was quite surprised that it could make such a difference. My right ear apparently had more cerumen buildup than the left which resulted in left shift of phantom image. After ear irrigation phantom image is dead center.It could also be that one of your ears is dirtier than the other and needs cleaning, whereas your partner's are pristine. No joke, it happened to me.
The 180° advise should help you finding out.
I've become obsessed that my right speaker is louder than my left speaker.
I've asked other people and they say it's not louder. I've swapped over connectors and that doesn't change anything.
I don't have measuring mics but tried measuring SPL from pink noise using my phone at a measured distance from each speaker in turn and it shows no consistent difference.
I sit closer to the right one during the day and I think that has altered my perception to the point where when I then sit equidistantly from them, it still seems louder. Is that possible/likely?
Did you swapped the speakers?I swapped the speaker cables over and still same effect/illusion
I ‘m actually honest, I would really use some tips because i have literally been fiddling with this for months.
The measurements i showed were after EQ.
The image center for me is in between the actual center and the left speaker.
I want to try corrections in the time domain but i have no experience in that.
Just because the sum doesn't look nice? On the other hand when you correct them as a sum the individual L and R responses don't look good, so in my (also asymmetric) room I chose between both options by ear and correcting L and R individually in the bass sounds much more balanced.I also learned some interesting things with these measurements and corrections. The bottom left prediction (C7) for separate left / right correction show that equalizing separately the left and right speaker below 200 Hz is useless. They must be equalized together.
