Expansive Atmos performance ; Good bass extension ; Clear dialogue channel ; Great price

Front-heavy delivery ; No DTS support ; No expansion options

A capable and competitively-priced Atmos soundbar that delivers deep bass and immersive audio using an easy-to-setup system. The soundstage is understandably front-heavy, but the delivery is precise and detailed, making the Polk Signa S4 a great...

Compact design Ultra-simple setup Very clear dialogue Excellent Dolby Atmos sound Great for TV-based music

No EQ adjustments No Wi-Fi/AirPlay/Chromecast No HDMI outputs

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

Dolby Atmos audio is excellent ; Subwoofer delivers critical low end ; Three levels of Voice Adjust dialogue enhancement

No Wi-Fi for music streaming ; Can’t be upgraded with rear speakers

The affordable Polk Audio Signa S4 soundbar and subwoofer is a fantastic way to experience immersive audio, but it can’t be upgraded with additional speakers, and you’ll have to do without Wi-Fi.

Bluetooth-compatible. Adjustable dialogue enhancement feature. Bass adjustment feature.

No treble adjustment. Lacks low-bass. Downmixes surround sound into stereo. No Wi-Fi, Chromecast, or AirPlay support.

The Polk Audio Signa S4 is fair for mixed usage. Its slightly V-shaped sound adds extra punch in the bass and brightness in the treble to your favorite music. Dialogue reproduces quite clearly and accurately, too, and its adjustable dialogue...

Energetic sound quality with movies and music ; Dedicated Dolby Atmos height channels ; Highly configurable sound modes

No Wi-Fi ; Unable to adjust volume of heights ; Lacks surround capabilities

Room-filling Dolby ; Wireless subwoofer connection ; Vocal clarity despite heavy background noise ; ‘Cinema’ mode ; 3 ‘Voice adjust’ modes to suit your preference

When it comes to hi-fi and home theater, I'm a space hog. Some folks zero in on tight, room-shaking bass, others seek immaculate midrange accuracy or high frequency extension with gobs of etched detail. For me, it's always been about imaging and...

Despite some connectivity shortcomings, the Signa S4 definitely delivers a good soundbar listening experience for both movies and music. In addition to Dolby Atmos, the inclusion of Voice Adjust also makes the S4 a good option for those that have...

Une qualité audio convaincante pour les films et la musique, modes audio hautement configurables, canaux Dolby Atmos dédiés

Pas de Wi-Fi, impossible de régler le volume vertical, impossible d'ajouter des enceintes à l'arrière

La barre de son Polk Signa S4 offre de très bonnes performances Dolby Atmos et une belle qualité audio grâce notamment à ses haut-parleurs verticaux physiques. Une caractéristique très rare à ce prix qui en fait le meilleur modèle sur son segment pour...

Enveloppe surround naturelle ; Ampleur quelle que soit la source ; Liaison acoustique barre/caisson ; Simplicité d’installation et d’utilisation

Connectivité limitée ; Pas d’afficheur en façade ; DTS non supporté

Cette barre de son représente un excellent compromis entre simplicité et performance. Les effets sonores sont réels sur les côtés, un peu en hauteur. Cela fonctionne aussi bien à partir de sources stéréo, 5.1 et Atmos. Et le caisson joue correctement...
