The SJ9 does the same thing. The two upward firing speakers seem to be angled at 45 degrees. Unlike some other Atmos sound bars I looked at, there doesn't seem to be a facility for calibrating those speakers to the height of your ceiling. Not sure how useful that is anyway.Thanks for your info. your take on the Atmos implementation would be great. Other soundbars like the Samsung use the bouncing against the ceiling - I gather the LG does not go this route.
Also, I tried using LG SoundSync via Bluetooth to connect the soundbar to my 65B6. It works fairly well and sounded fairly good. Changing the volume showed the regular B6 volume bar (with a Bluetooth icon next to it) rather than the "+" and "-" icons when controlling the volume via HDMI-CEC/SIMPLINK. The issue I found is that it wouldn't automatically reconnect via Bluetooth after turning on the TV and required manually reconnecting.
