How is my setup?

You really should not have to do that. I'm almost guaranteeing that you'll like them. The towers and center I linked you aren't the exact same speakers or else the center would be a tower too. In any case, it would be best to have timbre-matched speakers (which they are.) If you had more money you wanted to spend and had the room, you could order three pairs of the towers and ask for a single tower for a 7.1 system that completely matches. It isn't necessary to do that, but if had the money, will, and space...
