Does not appear that anyone asked what your front end (amp/pre/etc) is going to be in this setup? Important info that would really impact what speakers would/could be a good option for you.
Also, is this going to be a true dual system (2 channel and HT together)? I know you mentioned that you may add a center channel at some point, but if this is not something that's a priority to you, and you are ok with running 2 fronts and sub, that would also open up quite a few different options. (Alta Audio Celesta FRM-2's for example which are some of the best monitors on the market currently).
