The Stage had a longer ribbon and was larger than the Minors. The Centaur (not Major, not Minor) had the same size ribbon as the Stage but used a bigger driver than the Minor (8" vs 6"). The Major had a longer ribbon than the Stage and a 10" driver, I believe. Stages likewise benefit from Apogee stand mounting (consider it mandatory to get them off the ground somehow)-- better yet, get the Apogee stands/subs combination and have a Mini-Grand system. I owned Stages, Centaurs and Centaur Minors and thought that each had their strong points. In fact, I still have a pair of boxed Centaurs but I've been too lazy to double box and ship them to interested parties. I pulled them out of the bedroom system in concession to my better half for the CLS/SW800 array in the living room ;-)
