[Klipsch surround system]

I am planning out my speaker system for a new home theater setup.  I am thinking about the following combination for a 5.1.4 system:

 

RP-280F for fronts

RP-450C for center(maybe RP-600C)

Klipsch R-120SW sub

 

CDT-5650-C-II for atmos(qty of 4)

R-5800-W-ii for surround(qty of 2)

 

Does this sound like a good combination?  Any suggestions for alternates?

 

If not Klipsch, I am considering Elac Debut 2.0 or Emotiva Airmotiv speakers.

 

Thanks,

Scott
