Philharmonic Audio BMR Monitors or BMR Towers.
I move around my room all the time and while I can detect some improvement in overall refinement in the sweet spot, they also sound very good while standing at my desk in the back corner of the room. Moreover, they pass another test: they sound just as good outside the room as they do inside. (Yes, of course there are some changes, however they sound completely clear and even dialogue is intelligible when I'm in the living room!)
There are many ways to look at this, but I do agree with wider dispersion speakers.
