[QUOTE="Warbleed, post: 3098708, member: 549898"] Fs does NOT tell you the lowest frequency that the driver will PLAY. It tells you the Free Air Resonance of the driver. FR is Frequency Response, and is thus a rating for frequencies the driver can play. Sometimes they specify tolerances (i.e. +/-3dB) as well. Sometimes these are fairly honest, and sometimes they are not at all honest. You have to bear in mind Fs is a DRIVER parameter, and realistically FR is a SYSTEM parameter (driver + enclosure + environment) and thus the two often will vary considerably, even if both are being given honestly.
