Thanks to everyone for there input and replies. I have left a message for Kruncher to try and set up time I could listen to his M22's.
It's good to know that Sirquack thinks that I might not need a sub for this room if I go with the M80's.
I am just a bit tentative to make this purchase without 'hearing and touching' the speakers. I have to say the forums and many online reviews has made this decision easier.
Thanks again to everyone for their thoughts.
Andy
