That right speaker is just BEGGING to be pulled out of the corner, and both speakers would benefit from
being pulled away from the wall behind them.
Another idea would be to put your console in the corner, and a speaker at each wall (katty corner), firing
down the diagonal (if you can put a listening chair down the diagonal... even something like a dining
room chair that you can try and easily return to it is "correct" location
Experiment - and have fun with the process. You'll get there!
