Lifelike Cinematic Audio

Signa S4 is Dolby Atmos Certified* to immerse you in 360 degrees of surround sound. From added ambience in music to special effects flying overhead, Signa S4 provides an incredibly realistic sound environment. Plus, standard audio played through the Signa S4 can be up-mixed to create a virtualized Atmos experience. * Requires HDMI eARC connection between sound bar and TV

Advanced 3.1.2 Sound Bar

The Signa S4 sound bar’s advanced seven speaker array was designed to deliver a lifelike Dolby Atmos 3.1.2 listening experience. Its dedicated center channel provides crystal clear dialogue and its optimized left and right tweeters and woofers deliver a huge, wide sound stage. Plus, dual, up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion.

Polk Voiceadjust™-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.

Optimized Sound Modes

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

Deep Effortless Bass

Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at levels of loudness that’s surprising for its size. Polk's exclusive BassAdjust controls bass on both the sound bar and sub ensuring maximum impact and blending. The subwoofer connects automatically on start-up and can be conveniently placed nearly anywhere in the room. Put it up front for maximum impact or try behind the couch and feel the rumble.

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.

Powerful Home Cinema

The Signa S4 Dolby Atmos 3.1.2 sound bar with wireless subwoofer delivers powerful, crystal clear, cinematic 3D surround sound—at an unbeatable value.

  • And with our patented VoiceAdjust ™ technology, even with a dramatic room filling sound track you'll still hear every word.
  • And with sound modes optimized for movie watching and music listening, and night mode for late night viewing, Signa S4 fits perfectly into your lifestyle.
  • Expect great sound. Delivering top-shelf performance at an incredible value, the Signa S4 is the Dolby Atmos sound system you've been waiting for.
