I have the Klipsch ones attached to my Mini and I love them. Used to have a pair of the original Bose computer speakers and the Klipsch ones blow those away. (Don't remember the model, the new model comes in silver) The Klipsch speakers are really nice. They have great range and can get very, very loud. I usually don't have the sub turned up over 1/4 and the volume over 1/3.
I hear good things about the Soundsticks however have never seen a pair of them outside of a store.
