I dont think you need to bring your spks close, infact it would be a good idea to move them apart some more and then tow-in towards the audience and Ideally the tweeter should be at audience seated ear levels. SUB can be moved to a corner and the center towed down towards the audience, that should be it......BTW I was wondering how have you placed your surrounds ???, those are the most trickier ones.
Ah! keep equal distance of your left & right speaker from the TV, your right spk seems a bit more due to the rack.
