In addition to size, I would also say that if people buy them without first auditioning them, they may be disappointed in the relative lack of dynamics as compared to a traditional cone speaker. Especially for those who like to "rock the house down". If you are preconditioned to a cone speaker, the Maggies may come off as a bit of a shock to the uninitiated. However, if you stick with them over the initial shock, you grow to love the open and natural sound they throw off - especially the older models.
I also agree with those above that say that these speakers need a good amplifier with sufficient power in order to show there stuff. They can sound constricted and flat if under powered.
