You've got two things happening. With a 6" wide baffle there's a 6dB diffraction step happening around 2KHz; an 18" ring the way you have it would lower that step to 800 Hz or so, giving a lot more mid presence. The second thing is Allison effect, the out of phase reflections coming back off the wall behind the box, which are also being pushed lower in frequency by that ring. If you want to maximize performance cut a hole in the wall and flush-mount the face of the cabinet with the wall. Now you have no diffraction step or Allison effect- but maybe one very pissed off landlord.
