I'm thinking of upgrading from a 5.1 to a 7.1 system. All my speakers are Missions. 774 front, center 77c, rear 77ds.The sub is a Paradigm PDR 10.

Would Mission cubes be a goog addition for my setup or would I need something more substantial as front highs.

Also considered the CA Minx

Any suggestions are welcome
