Big Room questions

My room is 32x26x16 ave (say 11-12,000 cu.ft.after subtracting some indents) and I am looking to do a HT system over time. Currently I mostly listen to music so 2 channel musicality is important and I will probably build the 2 channel system first . I am probably going to replace my amp with something like the 7500 (can't see my wife going for a 7 channel system) and was considering the axiom 80ti's for mains. Looking for recommendations for subs for this large a space-thought about two lfm-1's but concerned about accuracy and musicality. Also considering getting 1 SVS PC12/ultra with the addition of a second later if needed for theater. Thoughts regarding the subs (or the axioms?) for a room this big. Other suggestions?

i would get the nicest velodyne that your budget can afford. i dont think there is anyone out there in the league of their nicer subs even if some have similar specs or whatever.
