This is the LG SK9Y soundbar. It supports Dolby Atmos, Dolby TrueHD, etc. Comes with a wireless subwoofer. The soundbar itself has 5 speakers supporting 5 channel surround sound, plus 2 upward-firing overhead speakers to fill the room, and to take advantage of the newer Dolby Atmos soundtracks, which create a more immersive, 3-dimensional soundscape. I opened this unit and tested it out, but decided to go with a receiver instead. Works and sounds great. It has also been updated to the latest firmware. Now allows you to control the center speaker volume independently. Smoke-free, pet-free home. Sells for almost $700 on Amazon. Will entertain reasonable offers.
