No it certainly didn't. But if you can picture the middle line as the back wall of my listening area and draw an imaginary line from the right edge of the middle line you have my listening area, Left and right speakers are about 6 inches from each side and about 12" from the front wall. I have a couch butted up against the mid wall and my surrounds pretty are pretty much line up with the fron speakers over the couch against the mid wall. In my picture I was trying to give the impress of the inverted C nature of my basement. The front wall extends another 8 feet right of the imaginary marker and then extends about 20 feet down. My question is do I keep one sub along the imaginary axis or extend it all the way right against the sliding door closets on the right that aren't really in the confines of my listening area. I hope this explains things better.
