Outdoor L-Series speakers have been released. It seems that the ceiling-mount speaker strobes have the same asymmetric design that was seen in the prototypes (although the final design looks less like MS Paint). The datasheet does not mention any 8-watt variants of the speakers, although those were mentioned in the ESD slides.
Also, LED chime strobes have been available from distributors for a while, but the datasheet has now been posted. It seems that these chime strobes will come with FIRE or FIRE/FEU lettering, unlike the original L-Series and SpectrAlert Advance chime strobes (which had no lettering).
