Upgrading your home theater sound can be a game-changer, transforming movie nights and music listening sessions. For months, I struggled with the tinny audio from my older television, making even my favorite films feel less impactful. A high-quality soundbar like the Polk Audio Signa S4 Soundbar would have solved this problem, enriching my entertainment experiences significantly.
Soundbars have become increasingly popular, offering a convenient way to enhance the audio quality of your television without the complexity of a full surround sound system. They address the common problem of inadequate television speaker sound, providing richer, more immersive audio for movies, music, and gaming. The ideal buyer is someone looking for a relatively easy-to-install, space-saving solution that improves their TV’s audio significantly without breaking the bank. This system isn’t ideal for audiophiles seeking the ultimate in high-fidelity sound or those with exceptionally large rooms, who might benefit from a more powerful, multi-speaker setup. Before buying, carefully consider your room size, your budget, your existing home theater equipment (if any), and the types of content you most frequently consume.

Exploring the Polk Audio Signa S4’s Features and Benefits
Dolby Atmos 3D Surround Sound
The Signa S4‘s Dolby Atmos capability is its standout feature. The up-firing speakers create height channels, placing sound effects above the listener, effectively immersing them in the audio landscape. This is especially noticeable in movies with plenty of overhead sound effects, like helicopter scenes or rain, giving a much more realistic experience than traditional 2.1 setups. The difference in movie watching is phenomenal – the sound is less flat and seems much more alive, enhancing the overall entertainment.
Wireless Subwoofer Performance
The included wireless subwoofer delivers surprisingly deep and powerful bass. While the size is relatively compact, it adds a significant impact to action movies, music with a strong bassline, and even gaming soundtracks. It enhances the low-frequency effects, adding a powerful punch to action scenes and depth to music. However, you may need to experiment with placement to find the sweet spot that minimizes unwanted room vibrations. The wireless connection is generally reliable, but occasionally, minor dropouts occur.
VoiceAdjust and BassAdjust Technologies
Polk Audio’s proprietary VoiceAdjust technology is a welcome addition. This feature allows for independent adjustment of voice levels, making dialogue clearer and easier to understand, even in action-packed scenes with loud background noise. This ensures that even quiet dialogue can be heard easily. The BassAdjust technology allows for independent bass control, letting you fine-tune the subwoofer’s output to suit your preferences and room acoustics.
Connectivity Options
The Polk Signa S4 boasts a variety of connectivity options, including HDMI eARC, optical, and analog inputs, providing considerable flexibility for connecting various sources. Bluetooth is also integrated, allowing for wireless audio streaming from smartphones and tablets. This ease of setup and use is a benefit for the average consumer who doesn’t want to deal with complex wiring.
Ease of Setup and Use
Setting up the Signa S4 is remarkably straightforward. The included instructions are clear and concise, and the whole process takes just a few minutes. The remote control is simple to use, and the soundbar integrates seamlessly with most televisions.
User Experiences with the Polk Audio Signa S4
Online reviews consistently praise the Polk Audio Signa S4 for its impressive sound quality considering its price point.
