I haven't heard them, but the Von Schweikert VR33s are made to be positioned close the the back wall and seem to have very positive reviews. They are only available factory-direct from VS to save cost, and they are just a little over your target price if you can stretch.
Looking at the specs they seem relatively easy to drive so your receiver should be able to drive them. It'll probably sound much better than what you're currently hearing, but the VR33s will likely reward you with significantly better sound as you upgrade other components.
Best of luck.
