AWARD-WINNING PERFORMANCE

“Polk Audio makes some of the best sound bars on the market, and the new Polk Audio Signa S4 lives up to your high expectations—that’s why we named it the best sound bar for your home theater.”

ADVANCED SEVEN-DRIVER ARRAY

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 soundstage. Plus, dual up-firing speakers take advantage of Atmos’ height channels to send sounds over your head, rounding out your 3D sound immersion.

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? Hear every word with VoiceAdjust. This patented technology combines with Signa S4’s dedicated center channel to allow you to raise the volume of voices, making them clear and easy to understand, while leaving the rest of the soundtrack untouched.

“The Polk Signa S4 sound bar offers excellent Dolby Atmos performance and musical replay at the best price yet.”- CNET*

Optimized Sound
Modes

Sound modes optimize the Signa S4 for the best sonic experience for movie watching and music listening. 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.

Deep Effortless
Bass

Signa S4’s powerful wireless subwoofer provides the deep, effortless bass that Polk is famous for, at loudness levels that are surprising for its size. Polk's exclusive BassAdjust mode controls bass on both the sound bar and sub ensuring seamless 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 to feel the rumble.

“In terms of sheer audio bang for your buck, it doesn't get much better than the Polk Signa S4 sound bar.”**
