Sony has announced new SRS-series wireless speakers. The RA5000 and RA3000 have been designed with "room-filling sound" in mind, which entails a novel design meant to distribute sound horiztonally in all directions, at least. They can also calibrate this output with respect to the room they are placed in and its dimensions.

Fun design, should help them stand out after quite a few of their speaker designs have been "adopted" by certain other brands.
