If you are going for an Atmos or DTS:X system, do not go for dipole or bipole surrounds. Use monopole speakers all around. Also, I would much rather go for bookshelf speaker fronts and better subwoofers. The Klipsch 12" subs are just not very good. Bass is a big part of the dynamics, and you will end up with mediocre bass with your outlined system. I would go down to bookshelf speaker fronts using a 6" woofer or larger, and getting some serious 15" woofers, and no Klipsch subs. I would be looking at a a
Hsu dual VTF3 system, absolutely killer setup, and worlds better than the Klispch subs. With those beasts handling bass, you do not need the extra extension of tower speakers, so I would be looking at the RP-160 for the front left/right. As it is, your system will be bottle-necked by middling bass performance.
