Sound Quality

The Polk Audio Signa S2 offers a noticeable improvement over most built-in TV speakers. It delivers clearer dialogue, a wider soundstage, and a more immersive listening experience. The soundbar utilizes five full-range drivers to create a balanced soundscape, providing a more directional sound compared to TV speakers.

While the Signa S2 might not compete with high-end audio systems in terms of nuanced detail, it delivers a significant improvement in clarity, especially for dialogue. Movies, TV shows, and even news broadcasts benefit from the clearer and more defined sound reproduction.


The Signa S2 incorporates a wireless subwoofer to add some much-needed low-end presence to the sound. This is particularly beneficial for experiencing explosions, action sequences, or music with a strong bass foundation. The wireless design eliminates the need to worry about cable placement between the soundbar and subwoofer, offering a more flexible setup.

It’s important to remember that the compact size of the subwoofer might limit its bass capabilities. For users seeking a truly earth-shattering bass experience, a dedicated subwoofer with a larger design might be necessary. However, for everyday listening and casual use, the Signa S2’s wireless subwoofer offers a noticeable improvement in low-end presence compared to soundbars without a subwoofer.


The Polk Audio Signa S2 offers a variety of connectivity options to connect to your TV and other devices. It features HDMI ARC (Audio Return Channel), which allows for a single-cable connection to compatible TVs, simplifying setup. Additionally, it includes an optical digital input for connecting various devices like gaming consoles, streaming devices, or older TVs without HDMI ARC.

The Signa S2 includes a remote control that allows for easy control of the volume, bass level, and sound modes. While it might not offer the most extensive control options, it provides the essentials for a user-friendly experience.


The Polk Audio Signa S2 boasts a compact and minimalist design that blends seamlessly with most modern entertainment setups. The low-profile soundbar can easily be placed in front of your TV without obstructing the picture. Alternatively, mounting brackets are included for wall-mounting the Signa S2 below your TV for a clean and space-saving setup.

The build quality feels decent, with a lightweight yet sturdy construction. The design prioritizes functionality and affordability, offering a no-frills aesthetic that complements various home theater environments.


The Polk Audio Signa S2 positions itself as an attractive option for viewers seeking an affordable way to improve their TV’s sound quality. While it might not deliver high-end audiophile sound, it offers a significant improvement over built-in TV speakers with its clearer dialogue, wider soundstage, and the addition of a wireless subwoofer for enhanced bass.

Here’s a quick breakdown for users with specific needs:

  • Ideal for: Viewers seeking a budget-friendly way to enhance their TV’s sound quality for everyday listening, including movies, TV shows, and news broadcasts. Users will appreciate the wireless subwoofer for added bass and the ease of setup with HDMI ARC.
  • Consider alternatives if: You prioritize a powerful and nuanced audio experience with deep, room-filling bass. In such cases, exploring soundbars with high-end components or larger, dedicated subwoofers might be a better fit. Audiophiles seeking the absolute best sound quality might want to consider higher-end audio systems.


The Polk Audio Signa S2 emerges as a compelling choice for viewers seeking a simple and affordable way to elevate their TV’s sound. The improved clarity, wider soundstage, and the addition of a wireless subwoofer create a more immersive listening experience compared to built-in TV speakers. While the audio experience might not satisfy audiophiles seeking the most refined sound, the Signa S2 delivers a significant improvement at an attractive price point. The ease of setup, wireless subwoofer, and user-friendly features make it a good option for casual listeners seeking a noticeable upgrade in their home theater sound.
