I had to sell my RT800 towers that I had matched up with my CS400I center and use my RT7 bookshelves up front due to fitment problems with my towers. Would there be a better match center for the RT7's other than my CS400I, like maybe a CS350. The CS400I is too high to fit in stand below the TV and I have the same problem above the T.V but can make it work if I have to with a little carpentry work. Any ideas?
