Full range floor standing speaker???? 4K or so

I am looking for a really nice full range speaker for 4K or so used. I am looking for a really wide soundstage, with a speaker that is not too picky on placement....>I cannot pull these more than 12 or so inches from the rear wall. However distance to the side walls is not an issue. I really want to fill the room with lively sound.

Room is moderate sized 350 sq feet with an attached kitchen not included in this estimate.

I have a significant amount of power, symphonic line Kraft intigrated (which looks and sounds AWSOME), so power should not be a restriction.

I listen to mostly lively jazz and classical.

Ok help me out folks and have fun.
