Now for something really different.....
Try moving your speakers closer (yes closer!) to the side walls BUT toe them in so that the axis of the speaker crosses well in front of you. Several thing will occur:
1) You may not find a meaningful change in the bass frequencies assuming you have them well out from the back wall;
2) You will eliminate much of the 1st reflections from the adjacent side wall and can easily tame the residual with minimal treatment;
3) You will change the 1st reflections from the ceiling to some degree, but more importantly you will alter the effect of the 2d reflection (and subsequent reflections) substantially, which can be a good thing;
4)you get to move your listening position further back from the speakers - its possible, depending on your room, to get an 8' speaker spread which should allow a listening position 8 to 9 ft back; and
5)You will get a pretty good stereo image for others when you have guests who will be sitting to your side; and
6) You may get a better, more solid center image.
Just something to think about, it's worked for me on many occasions.
BTW, plotting with the Cardas system is just a good starting point, it ain't the end all, Actually, I did use the Cara program on the Rives site and it pegged my speaker location perfectly, but missed the listening position by a foot. Try it - it even lets you select from different speakers.
