You might try setting up on the diagonal .
Set the speakers up an equal distance , along the wall , out from a corner firing into the opposite corner where your chair will be . Try to put the speakers the same distance apart as the distance to your listening position and a couple of feet away from the wall in each direction behind them . The distance from this wall will not be as important as usual because it is on a slant . Play with toe-in or a lack of it .
The price is right !
Good luck
