These speakers perform well for small to medium sized rooms, but dont forget to put a nice subwoofer in that mix.
I heard them at last but thought the Pro Cinema 100 sounded better. The Mythos were in a smaller room, the Pro Cinema 100 were in a very big room and sounded incredible with the movie. It was Star Wars and they were using a Yamaha receiver. The Mythos were connected to a Sony ES receiver, maybe that was the difference.
