Polk Signa S4 Soundbar
The Polk Signa S4 is a 3.1.2-channel Dolby Atmos soundbar system with a wireless subwoofer for television and film sound in medium to larger rooms.
A dedicated centre channel supports dialogue, while two up-firing drivers add the height layer and Polk VoiceAdjust lets speech be raised independently.
Connect through HDMI eARC for compatible immersive formats, or use optical and analogue inputs with older televisions, then set the listening mode and bass level to suit the room.
