Vandersteen makes a center channel (actually 3). I also have 2CE Sigs. I thought about the Vandersteen as my center, but it is a bit of an awkward size for my set-up, so finally went with an Elac Debut 2 center, (after a few others), bought it used, and quite happy with it for dialog. I have 1C’s as my rears. Some use the Vandersteen VSM-1 for that application, but you have options. I just had the 1C’s after my 2CE purchase, and used them. Keep in mind, IMO, you do not need ‘great’ speakers for the rears.
That said, I keep my 2channel and HT set-up amplification totally separate from one another as my 2 channel preamp has HT pass though. Thus, my AV receiver/processor is only used in ‘tv mode’, nothing else. If you go that route, I would advise the same.
I am not overly critical about my HT quality compared to my 2 channel listening. But believe me, it is more than adequate.
