I used to have the Mirage SM 0.5 in college and they were a real nice speaker. Those look like they might be the 0.5s big brother - maybe the 1.0 (long time ago, not sure of the model #s)
If they work, definitely scarf them up for $25! (and if you don't like/don't want, I'll buy them from you on the 12 th at the Rave as long as they function OK)
