About the Signa S3
The Polk Audio Signa S3 is a low-profile 2.1-channel soundbar and wireless subwoofer system designed to deliver room-filling TV and movie sound while fitting under most TVs. It features Polk's patented VoiceAdjust technology for clearer dialogue, Dolby Digital 5.1 decoding for immersive virtual surround from a compact bar, and an included wireless subwoofer for deep bass impact. Built to work with any HD, 4K, or 8K TV via HDMI ARC, it supports control with a single TV remote through HDMI-CEC and includes HDMI, optical, and 3.5 mm AUX inputs. The Signa S3 also offers Bluetooth and Wi-Fi with Chromecast built-in for streaming from apps such as Spotify, Tidal, and YouTube Music, as well as grouping with other Chromecast speakers for multi-room audio. Its ultra-slim bar can be wall-mounted with built-in keyhole slots.
