any comments on my speaker system ? I have all mission - M70 sub, M77DS rear, M74 fronts and M7C1 centre. Personally I think I could do with a better centre and a better sub as to my mind I think these are both maybe not so compatable with the other speakers - or am I just being fussy. Would appreciate some advice. I've also heard some poor reports on the M7C1 although mine does sound reasonably okay.
