Question about ARC2's combined L/R correction

To be honest I didn't even know this option existed, just goes to show how closely I read manuals (or even explore GUI's) 
 
But tonight I flipped it on, and after a lengthy recalculation had a good listen to some familiar music. 
 
The ARC2 site says "This new feature of ARC 2 improves the correction in high-end control rooms where the left and right monitors are positioned with absolute precise symmetry, improving the stereo image focus when working with elements panned dead-center in the mix - like vocals, bass, snare and so on."
 
However, my immediate impression was that it made the stereo image noticeably wider, in fact seemingly wider than my speakers when I close my eyes. Am I just imagining this? It does make my monitors sound noticeably better I have to say.

    I just tried this out on a tune with some dead center and full left/right tracks.
     
    I don't know how else to describe it, and it is subtle, but with Combined L/R Correction on, everything seems more firmly placed where I have them panned.
     
    I need to do more listening with a variety of material, but my initial impression is that there is a slight improvement with this on.

    It was from that thread that I discovered it!

    from ik's arc page:
     
    Where the room is acoustically very asymmetrical, the ARC processing can also compromise the stereo imaging, most noticeably on centre-panned sounds. A combined L/R Correction mode is available to resolve such cases, where ARC 2 averages the correction applied to the L/R channels and then applies it equally to both.

    translated to layman's terms: where the mix position in the room is so bad that you probably shouldn't mix there at all, you can use the combined L/R option to trick yourself into believing that ARC can help you by smearing whatever it measured before into some meaningless average

    well, that's not what my ears hear.
     
    i think it's just some basic math calculations going on here...

    I just realized something from this discussion.  I recently moved my monitors about 2 inches to make them a more perfect equilateral triangle with the listening position.
     
    Now I've got redo the whole ARC measurement!  Damn - I should have just let things well enough alone!

    Just food for thought:
     
    There was a recent thread where the op noticed ARC was causing mono material to sound stereo-ized in headphones because of the phase differences between L and R.
     
    Although ARC was not made for headphones, perhaps the "Combined L/R Correction" would solve this "problem" too, and/or verify that phasing was the cause?

    of course, I just took the marketing statement which is panned 100% to the positive side and panned it all the way to the ironic side ... it's up to every mix engineer to decide where to pan to their liking ...

    I just tried this out too, and it does help in my situation.  I have a speaker in the corner which creates way too much bass, but with ARC on, the difference in the two speakers is a bit too drastic.  With this setting on, ARC has a slightly less profound effect on the sound, but overall it is much more balanced and natural.  It is a nice option for me. I need to get used to it by listening to a bunch of stuff, but I'll be keeping it on for sure.

    I think that the phasing in question is intentional and integral to the correction. When heard on speakers in the room it's correcting for, it doesn't sound like phasing because it's moved the audio "in phase," but through headphones where that phase correction is not needed, the audio sounds out of phase.

    yes, this is 'monitor/room' correction, not headphone correction.
     
    sonarworks has that.
