For what it's worth I had a similar problem in my room with channel/loudness balancing. My pre-amp has no balance controls though so I solved the problem by moving my right speaker back (which was the louder of the two) a mere 1/2 inch...presto problem solved.
Prior to that little 1/2 inch move my room was set up perfectly symmetrical...I measured and remeasured many times.
A symmetrical set up is a good place to start, then listen to make final adjustments...and then suffer knowing that your right speaker is 1/2" different from the left!
