A review of the 5500's.
http://www.maximumpc.com/reviews/speakers/review_2004-10-18.html A word of warning.
On another site they said "Don't remove the stands, since the plastic mounting treads fall back into the speaker, and there is no way to retrieve them, with out taking the speakers apart, which is no easy task".
You will not be able to re-attach the stands.
