Jakeman, if you recall, I do not have the 600 going through the SMS-1, just the 350's. The 350's are setup on the front wall. It is 15ft wide and I have the drivers exactly 1/3 from the side walls, or 5ft apart.

The 600 initially was placed to the sides of the listening area, and at the same distance as the front subs, also taking into mind the 3ft delay.

I found that the graph was smoother when I placed the 600 along the back wall, close to the rear corner about 6ft in.
