Advanced 3.1.2 Soundbar

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.

Optimised 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.
