Try moving them (measured from side wall to center of front tweeter) 3 foot from side walls, and 22 inches from back wall (measured from wall to front center of tweeter) and try MLP at about 8 feet. Put DSP on near 1. Try toe in so right speaker passes to the right of your right shoulder and same for left side(passes to the left of your left shoulder). See if that opens up soundstage and imaging.
