Need advice on surrounds

Anyone have the 340SE mains and 340SE center and happen to have either the QS4 or QS8 surrounds? Due to our LP angle to the tv and mains (corner to corner), I may need to consider these surrounds b/c of how we have to angle them down and in a little, thus expanding the distance they are from the walls further than if they were simply mounted on the walls flat or even using the mounts.

Please advise if you have this setup as to if you like it and if the set compliments the 340's and potential HTM200 rear center as well as timbre match!?
