ander,
i don't own a pair of the promedia 2.1s so i can't be of much help. however, you should try the Klipsch.com forum. there is a place for 2.1s discussion only. there amy and justin can help you out. beware, most people there who post are because they have problems. they are the few that do have problems. those who don't have problems don't post. i guess that makes sense. good luck and have faith in Klipsch. they won't let you down.
