I do not like your speakers covers. I don't really like the covers on my Interludes, either, but generally I use mine, so don't feel too bad. The towers covers on yours that wrap around the base look really tacky, and I would ditch the covers on those. And the placement is bad on the towers as others have said. But I would leave the cover on the anemic 2 way center channel and flip it upside down and place it behind the TV offset a little on one side or the other so the tweeter isn't totally blocked by the base, and move the TV forwards. Just up the volume a little on the center channel to compensate for being behind the TV. I placed my center behind my TV in my bedroom HT and above the TV in the living room HT.
Seriously though, I would consider buying a matching step up 3 way center channel, if it's available. 2 way center channels generally are just really weak on the crisp dialoge you want a center channel for. But you could use that 2 way for a center behind you in a 6.1 configuration, and the fact it don't match wouldn't even be an issue. Or mount the center just above the TV on a small shelf, or on a large one if you want to put other stuff on it.
