Interesting. I should have tried the VP150 in different positions all this time. The center channel was not as clear, but I took Ian's advice and bumped the level +3 and it was much better. Now I wonder if placement had anything to do with it. I have already swapped the TV so I cannot test the VP150. Well, I will go ahead with the self building and not worry about the ports. When the VP180 arrives in a couple of weeks, I will try it in the shelf, but I will also try moving it away from the back cross brace. Maybe out in front more.
