Now there is a "Loudspeakers" section on the Lexicon website and contained within is the SL-1.
This is the production version of the prototype they had been showing back in 2017.
This is a design that is following the functionality of wire-powered speakers with sound steering to a user designated location. The speaker itself seems to be reliant on a mobile device app to accomplish the sound steering as there doesn't appear to be microphones on the speaker for active feedback and correction (no mics also means "they" aren't listening to you either). With the way it is setup, this seems to qualify these as closer to active studio monitors rather than smart speakers.
