Dolby Atmos Certified 3.1.2 Sound Bar System

Signa S4 is Dolby Atmos Certified to immerse you in 360 degrees of surround sound. The difference between regular surround sound and Dolby Atmos Certified sound is that it provides a true 3D sound experience by the additional playback of audio on height channels. From added ambience in music to special effects flying overhead, Signa S4 provides an incredibly realistic sound environment. And when you playback standard audio through Signa S4, it can be up-mixed to create a virtual Atmos experience.

Wireless Subwoofer for Effortless Bass

Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at a loudness level that is surprising for its size. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front or in the corner for maximum impact or try behind the couch and feel the rumble.


Polk Voice Adjust - Hear Every Word

Tired of riding the volume control to hear the dialogue during quiet scenes? Have trouble picking out voices when the bass kicks in? Polk’s VoiceAdjust was designed to make sure that you hear every word. This patented technology combines with Signa S4’s dedicated center channel to allow you to raise the volume of only the voices, making them clear and easy-to-understand, while leaving the rest of the soundtrack untouched.


Customizable Sound - Music, Movie, Night Modes

Late night binge-watching session? Don’t worry about waking your family or neighbors. With Night Mode, one button lowers the bass while increasing VoiceAdjust™ so you can hear every word, without raising the master volume. Plus, one-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening.


Sets Up In Seconds

Set up is easy: simply connect the included HDMI or optical cable (or aux-in for older TVs) for the ultimate sound quality for any TV—even the latest 8K Ultra-HD TVs. Signa S4 is pre-programmed to work with most TV remotes and it quickly pairs to your mobile device via Bluetooth to stream your favorite music. Lastly, Signa S4’s low-profile design won’t block your TV or your remote and can also be wall-mounted for flexible placement.


50 Years of Engineering for the Perfect Home Theater Sound

Signa S4 was designed in our Acoustic Research and Development center outside Baltimore, MD by the speaker experts at Polk. We’ve leveraged over 50 years of American hi-fi loudspeaker engineering so Signa S4 will deliver the thunderous, crystal clear, cinematic surround sound experience you’ve always dreamed of in your home—but at a value you could never imagine.
