Well, in my humble opinion, putting them in anything but a dedicated two channel system is a waste anyway. I am of the mind that dual purpose systems always compromise the performance of one or the other format due to either speaker placement or electronics. Both can sound good, but neither is optimized.
While I'm sure they can perform very nicely with movies, so can a myriad of other speakers. These sing (pun intended) best with music.
Sell them if you have to. At 2500.00, you should have no problem.
