LG has launched the StandbyME Speaker, which can link wirelessly to the StandbyME rollable display and act like a soundbar. The Bluetooth speaker can also work as a standalone unit and connect to other Bluetooth-enabled devices. It's currently available in the US and Korea for $200 and is scheduled to roll out in other markets.https://www.notebookcheck.net/LG-StandbyME-Speaker-launches-as-a-Bluetooth-speaker-that-doubles-as-a-soundbar.811706.0.html
Where in the world you got the "rollable" part from? That StandbyMe TV is just a solid, flat LCD TV with a tall stand.
