Polk Signa S4


The Polk Signa S4 is a capable, affordable and easy-to-setup Dolby Atmos soundbar and subwoofer combination

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...

Polk Signa S4 Soundbar review: Simply better TV sound


Polk's latest soundbar lacks features like voice assistants, AirPlay, and Chromecast, but it has killer Dolby Atmos sound and a setup that couldn't be easier.

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.”

Polk Audio Signa S4


The 3.1.2-channel Polk Signa S4 soundbar and subwoofer combo delivers impressive simulated surround sound at a reasonable price.

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.

Polk Audio Signa S4 Soundbar Review


Performance Features Ergonomics Value

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...

Big sound for my LG C1 65 Inch TV


Took a bit of tweaking to get the perfect setup with this unit as it doesn't have fancy echo technology, but raising the front of the sound bar by a small wedge gave the right direction to bounce the Atmos speakers of my ceiling while sat in my...
