I have a 4 x 5 m room and I have dynaudio dm 2/7 and would recommend an audition. Some might say they are too big for a room my size but I love the depth of bass.I had booming issues when they were new but after a month or two I have zero boom now.I heard the audiolab 8200a with these and they sounded great.I think you can get them at a reduced cost now.
