Don't forget though, that in movies, the center channel passes over 60% of the sonic energy...The percentage used to be greater with Pro Logic setups (>70%), but, nonetheless, the majority of action is happening on your screen, or behind it, as the mounting case may be. The main L & R, and secondary L & R fronts, in some systems configured as such, are obviously important, as well, as are the surround channels. In my opinion, though, there is too great an amount dedicated to a driver array that would not be "there". Plus, if one is interested in running a spec system (be it THXU2, THXU1, THXSelect1/2, or just a great 5.1 configuration), one should at least run with the basics covered, at first, and make additions/deletions from there...
