Yes, you can buy all five speakers of the same model and the timbre mathcing will all be the same. The problem for some is that they prefer to sit the center speaker on top of the T.V. Since the 803 is a floorstander it will be difficult to do this. If this is a concern, buy 4 of the 803s and then find a center channel such as the B&W Nautilus HTM1. If this is not a concern then get 5 of the 803s.
