Short answer: the Samsung HW-Q800F. It ranks #1 of 16 soundbars with a subwoofer by sound quality, rated 3.7/5, at $537.99. The Polk Signa S4 ranks #10, rated 3.4/5, at $449, $88.99 cheaper, which does not close the gap in sound quality.
The Samsung HW-Q800F is the better-sounding pick. A 5.1.2 bar with up-firing drivers and a wireless sub that digs deep, so action scenes have real weight. It streams over Wi-Fi as well as Bluetooth, which the Polk Signa S4 cannot. The catch: There are no rear speakers in the box, so surround effects stay in front of you unless you add Samsung’s optional rears.
The case for the Polk Signa S4: A full Atmos package with up-firing drivers and a wireless sub, so movies gain height and real bass weight out of the box. Watch for: The sound stays mostly in front of you, so surround effects are limited, and RTINGS found it only fair for music.
Buy the Samsung HW-Q800F. It is rated higher for sound quality, and the $88.99 saving on the Polk Signa S4 is not enough to make up the difference.
