Sound Quality

The Polk Audio Signa S4 delivers a well-balanced soundscape that caters to a variety of content. Movies come alive with crisp dialogue thanks to the dedicated center channel. Voices remain clear and discernible even during action-packed scenes, eliminating the need for constant volume adjustments. The left and right channels create a decent soundstage, effectively separating instruments and sound effects in music and movies.

For those who crave earth-shaking bass, the wireless subwoofer does not disappoint. It delivers deep, impactful lows that add richness to explosions, basslines, and other low-frequency sounds. The beauty lies in the adjustability. The subwoofer level can be fine-tuned to your preference, allowing you to tailor the bass intensity to your liking. This is particularly useful for apartment dwellers or those in shared spaces where excessive bass might be disruptive.

However, it’s worth noting that the soundstage of the Polk Audio Signa S4 might not be as wide as some higher-end soundbars. This is to be expected from a 2.1 channel system. Additionally, audiophiles seeking the most pristine highs might find the overall sound profile a tad on the warm side. Nevertheless, the Signa S4 delivers a satisfying and balanced sound experience for casual listeners and movie enthusiasts alike.


Let’s talk bass. The Polk Audio Signa S4 boasts a wireless subwoofer that brings the low-end rumble. Explosions in movies pack a punch, while basslines in music thrum with satisfying depth. The ability to adjust the subwoofer level is a big plus, allowing you to tailor the bass to your preferences and listening environment. This is particularly useful for those who live in apartments or shared spaces where excessive bass might be disruptive.

While the subwoofer delivers impactful bass, it might not be the most nuanced for audiophiles seeking the most controlled low-end experience. In some instances, the bass can be a tad boomy, especially in smaller rooms. However, for the price point, the subwoofer adds a significant layer of richness and excitement to your home theater experience.


The Polk Audio Signa S4 embraces a user-friendly approach to connectivity. It features an HDMI ARC (Audio Return Channel) port that allows for a single-cable connection to your compatible TV. This simplifies setup and ensures compatibility with high-definition audio formats. Additionally, the soundbar offers an optical digital input for older TVs or devices that lack HDMI ARC.

For wireless music streaming, the Polk Audio Signa S4 boasts Bluetooth connectivity. This allows you to stream music directly from your smartphone, tablet, or laptop, adding versatility to the soundbar’s functionality. While it might not offer the most extensive connectivity options compared to some high-end soundbars, the Signa S4 covers the essential bases for most users.


The Polk Audio Signa S4 adopts a minimalist design aesthetic that complements most home theater setups. Its low-profile design ensures it won’t block your TV’s bottom edge, while the included wall-mounting kit allows for a clean and space-saving installation. The build quality feels solid, with a metal grille that exudes a touch of sophistication.

Overall, the design prioritizes functionality without sacrificing aesthetics. The clean lines and understated profile make the Polk Audio Signa S4 a suitable choice for those who value a discreet soundbar solution that blends seamlessly into their entertainment space.


The Polk Audio Signa S4 prioritizes user-friendliness. The included remote control offers clear and well-labeled buttons for easy navigation of volume, sound modes, and other settings. The soundbar also displays basic information on its front panel, providing visual cues on the selected source and volume level. Additionally, the setup process is straightforward, with clear instructions and all necessary cables included in the box.


The Polk Audio Signa S4 soundbar emerges as a compelling option for budget-conscious users seeking a feature-packed home theater solution. It delivers a well-balanced soundscape with clear dialogue, a decent soundstage, and impactful bass from the wireless subwoofer. The soundbar offers convenient connectivity options, including HDMI ARC and Bluetooth, making setup and content streaming a breeze.

While the soundstage might not be as wide as some high-end soundbars and the bass might lack the ultimate nuance, the Polk Audio Signa S4 offers a significant upgrade over most TV speakers. The user-friendly design, simple connectivity options, and immersive sound experience make it a well-rounded choice for casual listeners and movie enthusiasts seeking a cinematic audio boost without breaking the bank. If you prioritize absolute audio fidelity or crave a wider soundstage, you might want to explore higher-end options.
