The coolest trick at CES was Summit Semiconductor's WiSA (Wireless Speaker & Audio) technology and the way it could literally move the sweet spot from the usual front-and-center position off to the side or to the back of the room. It was uncanny. WiSA spreads uncompressed high-res signals wirelessly among powered speakers. You're looking at the power/receiver board that makes it work. WiSA will surface first in Aperion products. The loudspeaker industry would be crazy not to jump on this, especially since it can be built into speaker systems selling for less than $1000.
