I have the FPS2000, and my friend just got a pair of klipschs, and i'm not really all that impressed. Sure it goes really loud, but i think there is too much treble and too much bass and not enough mids. So its like having your ears pierced of high frequencies and pounded to death with the sub. I prefer my FPS2000 over it. It might not go as loud, but their quality is 95% of the klipschs, and for $150 less, i think its really the best buy you can get..
