But still if you look at 3dsoundsurge the crossfires play louder with 100 watts. I think Klipsch could really deliver a killer system, but they don't want to out do their quintets. As for the amp, I've read it has an insane amount of power. It outputs 400 watts at full volume, but handles 600. The reason they aren't that loud is because of their efficiency. If they put higher quality drivers they would be more expensive but sound a lot better.
