I recently found time install ARC 2 and to do a new room measurement.  Results are great.  Stereo imaging particularly improved.  But there’s a big mystery.  My left speaker is getting noticeable bass correction, considerably more than the right speaker.  And like I said, it’s really helping the stereo imaging, so I have no complaints about how ARC 2 is performing.
 
But looking at the before and after graph line plots on the user interface, it shows the right speaker getting the bulk of the correction.  And, yes, my speakers are hooked up properly - when I pan left, sound shifts left, etc.  It seems to me that the right and left images are improperly switched.
 
Could some of you ARC 2 users check to see if you see the same phenomena?

 This is what mine looks like.

it's typical if you speakers are not in the center of the room (like me one closer to wall than another) ....

I don't understand the question. The idea is to make corrections that result in balance right to left. It shouldn't matter what that it starts with an imbalance and then corrects it.
 
If you just made the corrections recently it also makes sense that it may take a short while for you to forget what it previously sounded like and you'll get used to the new balance quickly.
 
It is also helpful to remember that the white line is a drawing of a white line and at best it's a prediction of what the intention is. The white line is not the result of a second round of analysis, so don't take the white line too seriously.
 
If ARC has improved your imaging then it seems like it is working. Yes?

Ya that's the kind of thing you'll see with Audyssey. Your room interacts with your speakers in weird ways and Audyssey fixes that. In my case, my front right speaker gets a massive cut at about 120Hz because there's a nasty eigenmode for it, since it is near a corner. My front left speaker is farther from the corner, since it is near the entry, and doesn't get the same correction.
 
That's a big reason to use it: Unless you've gone all out on room treatment and setup (and usually even then) there are differences in interactions from the different speakers. So you need some EQ to match them.

i suggest also a monitors swap time to time to not "use" one speaker more that the other ..one of mine is handling a lot of bass and the over is cooling ....that's why 2.1 system are great ij those configurations ..

My room was very very bad, and was off centered as well (one monitor near a corner, the other one more in the center of the room)
I experienced a very similar profile to this, but to be honest I think my room was so bad using ARC seemed only to make it worse.
So I stopped using it.
What I decided to do and am just doing now, was to rebuild my room / studio and build a purpose designed control / mixing room and a separate live / tracking area. Hopefully with all the treatment being done to the control room, it will be as near as perfect as I can make it (have spent a lot of time on ratios / sizes  / damping etc and some money), so I'm hoping I won't have a need for ARC.............. 

use both ;)

ARC 2 seems to be working brilliantly.  All I'm saying is that it looks to me like the "before" images on the right and left are swapped.  I've got more pronounced correction of bass in the left channel than in the right.  But the "before" pictures show the right channel as being more bass deficient.
 
Let me give a hypothetical.  Suppose your left speaker needed a lot of correction and the right was dead on perfect (in ARC's estimation).  On the left, you'd expect to see a white line and an orange line that are quite different, and on the right they'd be largely the same plot.  Now imagine the pictures are swapped.  That's what it seems like I'm seeing.
 
I have no complaints about what ARC is doing other than toying with my sanity.

The white line should be close to flat either way. The white line is the result, not the correction. ARC 2 doesn't show us what it's done to achieve the white (after) line. If I'm not understanding your question, forgive me.
