Hi, I've got 4 mission m72's and need to get a center. I'm tempted to get the B & W lcr60 over the usual complement to these speakers, the mission m7c2. I know the mission would be a better tonal match but I'm thinking of paying a bit extra on the centre as it's the main speaker for the 50/50 movies music I'll be playing. I don't plan to upgrade the m72's any time soon. Is it a bad idea to get a better quality centre but comprise on the overall system sound (if there's a tonal mismatch)? Anyone mixed mission and B & W speakers before? Advice appreciated!
