Axiom Home Page Forums General Discussion Home Theater Help: Asymetrical distance to listener position!

Having issues trying to layout my new 7.1 system. I basically have an open floor plan with essentially 3 walls.

My dilemma is to either place a QS8 in Position A on a speaker stand (more money ($143), could get knocked over, pain in the ass to run cable under the hardwood floor, but contractor can do anything).

However, there is a wall available at position B, which would be easier to run cable in the walls, no danger of it knocking over, but it is probably another 5-6 feet away from the center position.

What should I do here? Thanks!
