That's a difficult situation. Close proximity to a rear wall will affect response due to the boundary conditions. Good acoustic treatment may help quite a bit.
The problem is that most monitors are set up assuming a position well away from the rear walls. Mounting them closer will tend to bring up the bass levels, muddying the overall presentation. EQ can help here to some degree, though I know many are not fond of that prospect.
You may need to think about a custom build, one that takes into account your particular situation.
You have described the type of music you like . . . how loud do you like to play it?
