Welcome to the forum. \:\)

M3s do not have to overall output of the M22, read that as the M22s work better in a larger room and the M22s have more midrange/upper end clarity than the M3s. You can simulate the bass hump the M3s have(use without a subwoofer) with a boost of 3db in the bass management with the M22s.

That appears to be a fairly large room so I would recommend the M22s over the M3s, then again I prefer the M22s to the M3s so I am biased ;\)
