Direct radiating as you have enough room for some dispersion to take place. This is what the QS series mimics but with a near field listening position. If you were closer to the speakers by a few more feet I might then suggest some QS's. Now you may still prefer the QS series even with the extra distance, some people on the forum do, but I would start with the M2's and you could always exchange them if you are not happy.
