I have MA silver S6 speakers for music and will be using them for home cinema as well. Am going to add 2 keff eggs for rears and was going to get MA matching centre (as recommended for tonal balance). This centre would have to go above plasma and I think it will look odd with a big centre above. Can I get away with something like a keff centre? As I have 2 floorstanders how much more will a sub add? Thanks as always, I am getting so comfused. PS can you get kef or genie without sub?
