I'm not entirely sure what timbre matching is but I can tell you that I've noticed a serious difference in the sound of voices during some quick pans during some action scenes that have a lot of talking in them. It can be distracting but it is kinda rare. I know someone who actually replaced his 150 with a klipsch speaker(RC-64) and he claims that it sounds incredible and blends well with his M80's. Honestly, I've always been a little dissapointed with axioms centers. Just a little, though.
