I would try moving them at least 6 feet apart, (if not 7-8 feet) and pulled out from the back wall 3 feet, (if not more). 4 feet apart is way too close together for a proper stereo image.
The more you move them out from the wall the deeper the soundstage will get, but you will get a decrease in bass response, so you'll need to find a happy medium between depth and bass.
Also, toe them in just a few degrees to start, then try a little more until you hear just the middle images, then toe them back in until you hear your soundstage outside the physical boundries of the speakers.
