Sonos just sent out invitations to an October 4th media event in New York City. The invite comes just a few hours after Dave Zatz discovered reference to a Sonos smart speaker in the FCC.

The speaker, codenamed S13, features integrated voice control and far field microphones just like Amazon’s Echo speaker lineup. Uniquely, the S13 also lists support for multiple voice platforms in addition to multiple music services. The FCC filing also included the graphic below which you can see hinted at in the lower-right corner of the invitation. Otherwise, that Rolling Stones-esque mouth makes it pretty clear that this event will focus on voice.
