3.1.2 system with Dolby Atmos certified soundbar

Signa S4 is Dolby Atmos certified, to immerse you in 360-degree surround sound. The difference between normal surround sound and Dolby Atmos certified sound is that the latter provides a true 3D sound experience, thanks to the additional reproduction of audio on height channels. From the heightened atmosphere of listening to music to the special effects of cinema, Signa S4 offers an incredibly realistic sound environment. And when you play standard audio through the Signa S4, it can be up-mixed to create a virtual Atmos experience.

Wireless subwoofer for perfect bass

Signa S4's powerful wireless subwoofer delivers the deep, punchy bass Polk is known for, at a volume level that's astonishing for its size. The subwoofer connects automatically on startup and can be conveniently placed almost anywhere in the room. Place it frontally or in the corner for maximum impact or place it behind the sofa for a thundering effect.

Voice Adjust Technology - Hear every word

Tired of turning the volume up and down to hear dialogue better during sensitive scenes? Struggling to hear lyrics when the bass kicks in? Polk's VoiceAdjust was designed to make sure you hear every word. This patented technology combines with the Signa S4's dedicated center channel to allow you to boost the volume of just the vocals, making them clear and easy to understand, while leaving the rest of the soundtrack intact.

Customizable sound - with Music, Movie and Night modes

Late night movie and TV show marathon? Don't worry about waking up your family or neighbors. One-button Night Mode cuts bass and boosts VoiceAdjust™ so you can hear every word, without turning up the master volume. Plus, pre-selected sound modes optimize the Signa S4 so you can have the best sound experience for watching movies and listening to music. All in one button.

Set it up in seconds

Setup is simple: Plug in the included HDMI or optical cable (or the aux input, for older TVs) to get great-quality sound for any TV, even the latest 8K Ultra-HD TVs. Signa S4 is programmed to work with most TV remote controls and quickly pairs with your mobile device via Bluetooth to stream your favorite music. Finally, the Signa S4's unobtrusive design won't obstruct your view of your TV or your remote control; the soundbar can also be installed on the wall for flexible placement.
