The original poster is nowhere to be found,while others fight amongst themselves. We don't know much about his room. So I will cast a wide net of ideas. I messed around with my system for a couple years before I was satified with the sound. Your speakers look nice and should image well. Here are some factors that could cause your symptom:
Too close to side walls
Too close to back wall
Wired wrong
Excessive phase cancelling due to reflections, comb filtering
A sub can help focus the playback
Springs under speakers. This helps but something else is wrong.
If you have a dedicated room, then this is easier. Some of the setups mixed with furniture in living areas will sound just like your system does now. My guess is room treatment but need more information.
