Samsung Soundbar HW-Q800D

5.1.2 channel system with 360W total power output Effective Dolby Atmos and DTS:X 4K HDMI passthrough, but not at 120Hz The Samsung HW-Q800D is a true 5.1.2 channel system. Firstly, it has five channels on the main soundbar: one in the center; two more on the front, on either side of the center; and two on each end of the bar. Alongside that, it has two upfiring speakers on the top of the soundbar and a dedicated subwoofer. This configuration helps to deliver fantastically immersive audio – something only improved by Dolby Atmos and DTS:X functionality. When watching movies, I found Atmos to be very effective – you get incredible width from audio output, which follows on-screen action very competently. The upfiring speaker drivers also add impressive verticality for movies and TV shows – but I’ll go into more depth on that in the next section.
