I Tested them as mains in my bedroom when I first got them and they now are the surrounds for my bedroom 5.1 setup. I got them for the same reason. I did crank them up when I was watching Dracula, the untold story and I definitely think they are up to the challenge for the dynamic push in movies.
At a price point of $500 retail/pair, ~375-400/pair if you negociate, they are effective little speakers. You could also upgrade to the Superstat 50, but those will take up more much space and will cost you twice as much and at that price point I don't think it is worth it
