I can think of a couple of ideas, but since I can't see your room layout, only you will be able to determine whether or not they are feasible:
1. Since there's plenty of space on the right but not the left, why not move both speakers (and therefore the listening position too) by the same amount to the right, making them equidistant from the side walls?.
2. You indicate that your front mains are approximately one foot from the wall behind them. If you increase this distance, you should find that the bass will drop, and the clarity potentially increase. Remember; ideally, the listening position should be 1 to 1.5 times the distance
between your speakers,
from your speakers, and closer to 1 times, so with a current distance of 11 feet, you have enough room to lose a foot or two.
3. Adjust the bass contour knob.
