I have listen to most of the M3’s ... the on-walll is amazingly similar to an M3 ... at least at low to mid volume ... the in-wall and in-ceiling I’ve only heard uninstalled so I’ll have to hold off on my opinion. The The M22 is very good but needs a sub as it lacks low end. I’m guessing the M2 will be similar but bet that the lower mids will not keep up at the higher volumes ... I await your report ...
