First, and I apologize for stating the obvious, but your listening position must be centered between the speakers and to start with, the speakers should be identically positioned in relation to the rear wall (and if possible, the side walls). You dont state your room size; if you have a relatively small room I recommend setting your speakers/seating in an equal triangle (tweeters to ears). You may want to bring the speakers apart from one another (increase the six foot space) also, if they are towed in, try facing them straight into the room; if they are not towed in, try towing them in slightly so that the tweeters fire just to the sides of your ears. Youve probably already done all the above, so have you tried making small adjustments to the left speaker only (moving it back in very slight increments)?
Something else to consider is whether or not each of your speaker cables are the identical length. I agree with the above regarding correct phase. Its possible that you are getting some first reflections on the left wall, while the right wall may be diffused or absorbed (i.e.: furniture placement). Again, try adjusting the left speaker (and as stated above, treat the room).
