That Drunk Squirrel is smarter than he looks! He took the words right out of my mouth. That instantaneous reflection coming from those very near walls will blur your imaging. Toe in will delay it a bit, but for that width room you need to pad the area in front of the speakers. I have a similar problem in my room and taming that first reflection had a huge impact on the image. (Then again, it could be my speaker wire. )
