I believe the tweeter is off set only with the Left and right speakers not the centre.
what I mean by better musically is that the M22 frequency resp goes from 50hz up. Whereas, the MK's only drop to 80hz. Reason is for a bookshelf this is where a sub would take over. Therefore if the speaker doesn't have to reproduce below 80 then there would be less distortion and a cleaner sound. Why produce it if the sub will much easier and cleaner.
I think as Alan said they should blend nice with the QS8's and will try them out.
