That graph is not fine enough anyways.
I have owned the Klipsch subs and speakers in question. Their best attribute was sounding much bigger than they were and very cinema like. The subs can hold their own but you have to get them near cost because the FV15HP is better. The specs on the Klipsch subs are indoor specs. I say if the OP wants the cinema experience and size is not an issue go for the JBL pro 4722N's with 8530 surrounds. He can add dual OS's and he would have a system that would not only cost $11000 but kick some serious butt! The big problem is just that, this is a big system! To save even more money($3000) he can have someone build him dual GH's!
