If you can, try pushing the speakers all the way to the front wall. This will push the first front wall reflection above the baffle step frequency. Also move the sub further away from the left speaker, preferably to a wall boundary.
I know this isn’t the traditional advice, but that advice was developed before room correction was a thing. The raw response will have more bass peaks, but those can be corrected by Dirac.
