Go phantom for center channel info - nothing cheap will blend properly - you can't turn a pigs ear into a silk purse ;-)
More seriously - there are plenty of good reasons NOT to go with a center channel unless you can use the SAME speaker as your mains at the SAME height...the mix and mastering studio engineers who make your movie and concert sound tracks do NOT generally use a different center channel at a different height...for good reason too!
