Can b&w 804 be placed near wall?

I've tried googling this but no luck.  I'm looking at purchasing a pair of b&w 804's but have some limitations in my room.  My room is roughly 14'W x 21'D x 8'H.  The speakers will be on the short wall but I only have about 21" to work with off the wall.  So the back of the 804's would only be about 7" off the wall.

I do have MiniDSP SHD with Dirac for room correction so I would hope that can solve any problems.

Thanks!
