a) Position the monitors about 56 inches out from the wall behind them. The energy bouncing off the wall will arrive out-of-phase with the direct sound at about 60 Hz, hopefully causing a zig where your modal room interaction is causing a zag.
b) Place your subs as close as possible to the monitors, allow some overlap in the crossover region, and adjust your subs so that they are 180 degrees out-of-phase with your monitors in the crossover region. Find this setting by placing the monitor on the floor woofer-to-woofer with the sub, and playing test tones. The deepest null is the correct setting.
c) Reduce the output from your monitors' ports by stuffing fiberfill or open-cell foam into the port. Open-cell foam is foam that you can breathe through.
d) Reduce the tuning frequency of your monitors by inserting a somewhat longer (if possible), smaller-diameter plastic tube into the port. Wrap at least one end of the tube with enough electrical tape to give a reasonably secure friction fit.
