you may want to try running the vandies w/o a center channel. just tell your receiver that there is no center. i've been fiddling with this and actually like it alot, and you wouldn't have to worry about matching the center. this however, does lessen the sweet spot. but if there's only one or two people in front of the tv, it shouldn't be a problem. make sure to use the radio shack sound level meter to balance the levels of all your speakers.
