It is possible, and likely, that the difference in wall construction can cause this.
Are you sending your signals to both speakers at the same time?
It is not uncommon for rooms to have varying bass response for left and right side.  Do you hear it while playing music?

That and the windows are probably the culprit

well today I cleared out absolutely everything that was nonessential and lo and behold the phenomenon is still there albeit less pronounced...I can only assume it is a function of the difference in wall construction and the windows because with the exception of my DAW, the desk it's on and the panels the room was empty.

Moving the panels altered things a tad but less than removing the misc stuff in the room...interesting

Bottom line is I don't hear it when I'm mixing so it's of no great importance but it was interesting to see how removing the stuff in the room effected this phenomenon.

Anyway next step is to ETF the room and see what the results are.

It occurs to me that your door could be diaphramatic at certain frequencies which would explain the shift of certain frequencies to the left.

In fact there are two doors side by side on that wall (I forgot to put the second door in on the diqagram) and I agree there is a real probability that the two doors, in conjuction with the different wall construction and the windows on the exterior wall are creating this phenomenon.

That being said I will carry on merrily with my mixing / room analysis / tweaking / mixing / room analysis / tweaking etc. until I get the room as good (acoustically) as I can.

I think you've tracked it down. Windows, differing walls, and doors are all possible influences. A few things I saw from the pictures: since the bookshelves are open on the sides (not a bookcase) and sparsely spaced they aren't really going to be greatly affecting the bass. The filing cabinet against the wall may have, but you've removed that. Also, the size and configuration of the panels over the windows maintains the windows as a factor for your bass issue. So yes, less than a revolutionary post here, I know, but my vote says you've got a working idea of the problem. The good news is that problems like this, if minor, can sometimes be pretty benign in your everyday work. You may not notice it in context (I believe you've said as much) and your ability to work may not be significantly impaired. Good luck and good listening!

Thanks for the comments Jay.

I realise I've made a huge assumption here as to the cause of this panning phenomenon (as I call it) but it seems to make sense and unless one of the more knowledgeable members of the various forums I've posted to chimes in with a different explanation I'll just carry on in my ignorance.
