A 2017 CES Innovation Awards honoree, the HiVi Swan MS-10 ($4000/ pair) is a wireless active stereo system that resembles no loudspeaker that I’ve seen. (I kept thinking that it looks like one of those “ergonomic” office chairs.) But the separation of the woofer and mid/tweeter modules actually makes sense, and the speaker (on static display) certainly attracted a lot of attention in the Innovation Awards section of CES.
