You can easily get away with a well thought out non-matched center, while there is ofocurse a benefit to a matched model a bit of snob kicks in when people are asked about all matched speakers, mine match as of now but I have had excellent results in the past when older speakers simply didnt come with center options or budget kept a matched center from being possible.
I would choose a carefully thought out non matched center over phantom anyday of the week, if folks sit off axis its not going to work great and even on axis sometimes center info is hard to hear..........the center channel is there for a reason, its not just hype. Match all if you can, if you cant from center to rears just audition and you will be happy.......its not as cut and dry critical as many would make you believe and your ears will confirm this!
