I have had M3s with M22s, although the differences are minor, the M3s less honest qualities (and the 6.5" woofer) do not add to a seamless soundstage with the M22s. And since it is the tweeters that are causing the problems, I do not think an M3 would solve it.

Just my opinion tho...after having M3 centres with M22 mains, I ended up ordering M2 centres and they match a whole lot better than M3s...
