Another vote for M22ti, I'm matching them with a SVS PB1 and I couldn't be happier. My living room is almost identical to yours and they can play as loud as you can tolerate. Every now and then I still take my wife to rock concert(just went to Dave Matthew's couple months ago) so I know what loud music is, if you feed them enough power these M22ti have no problem cracking your ear drums with authority!!
