Introduction
If you are like me, you probably spent a decent amount of money on a high-definition or 4K television, only to realize that the built-in speakers leave a lot to be desired. Modern TVs are incredibly thin, which looks great on the wall, but it leaves almost no room for decent audio hardware. For the longest time, I struggled to hear dialogue over background music in movies, and action scenes felt completely flat.
I finally decided it was time to upgrade my home entertainment setup without cluttering the room with a massive, complicated surround sound system. After doing quite a bit of research, I landed on the Signa S4 TV Sound Bar with Subwoofer. It promised Dolby Atmos immersion, simple connectivity, and a wireless subwoofer that wouldn’t require me to run cables across my living room floor.
In this comprehensive review, I am going to break down my personal experience with the Signa S4, looking at the audio performance, the setup process, and whether it really delivers on the promise of a cinematic experience for $379.00. Whether you are a casual TV watcher or a dedicated movie buff, here is what you need to know.
Product Overview
The Signa S4 is designed to be an all-in-one upgrade for your television’s audio. It is a compact sound bar system that comes bundled with a dedicated wireless subwoofer. The main selling point here is the inclusion of Dolby Atmos technology. Atmos is essentially object-based audio, which allows sound to move around you in three-dimensional space—even overhead—if you have the right content.
The system features several key technologies meant to enhance your listening experience, specifically VoiceAdjust and BassAdjust. These features allow you to fine-tune the audio so that dialogue remains clear even when the action gets loud, and the bass is adjusted to your preference without overpowering the rest of the soundstage.
Connectivity is handled primarily through an HDMI eARC (Enhanced Audio Return Channel) connection, which is the gold standard for high-quality audio transmission from your TV to your sound bar. It is also compatible with 8K, 4K, and HD TVs, making it a future-proof choice for many years to come. Additionally, it supports Bluetooth for wireless music streaming from your phone or tablet.
Pros
- Immersive Dolby Atmos Sound: The soundstage provided by the Signa S4 is genuinely impressive for its size. When watching Atmos-encoded content, you get a much wider and taller sound profile than a standard stereo soundbar can offer.
- VoiceAdjust Technology: This is my favorite feature. If you have ever been frustrated by “mumbled” dialogue in movies or TV shows, this technology isolates and boosts the vocal frequencies, making everything sound crisp and clear without having to constantly ride the volume rocker.
- Easy Setup with HDMI eARC: Connecting the system was a breeze. Once connected via HDMI eARC, my TV remote automatically controlled the soundbar’s volume, meaning I didn’t have to juggle multiple remotes.
- Deep, Punchy Bass: The wireless subwoofer provides that low-end rumble that brings action movies to life. Because it is wireless, I was able to tuck it into a corner of the room where it was out of sight but still provided excellent acoustic impact.
- Versatile Connectivity: Between HDMI eARC, Optical input, and Bluetooth, you have multiple ways to get audio to the bar. Streaming music from my phone over Bluetooth was quick and stable, which is a nice bonus for when I’m not watching TV.
- Sleek, Low-Profile Design: The soundbar is slim enough that it doesn’t block the bottom of my TV screen or look bulky on my media console. It has a modern, minimalist aesthetic that fits well in most home decor.
Cons
- Virtual Height Channels: While the Dolby Atmos experience is good, it is still “virtualized” via software and up-firing drivers. It is not the same as having physical speakers mounted in your ceiling, so don’t expect a true, professional-grade surround sound experience.
- Lack of Advanced EQ Customization: While BassAdjust and VoiceAdjust are helpful, power users who like to fine-tune specific frequency bands via an app or an equalizer may feel a bit limited by the preset sound modes.
- Subwoofer Placement Sensitivity: Even though it is wireless, you still need to find the “sweet spot” in your room. If you place the subwoofer too far from the soundbar or behind certain furniture, the signal can occasionally drop or the bass can become boomy and muddy.
- Limited Physical Inputs: If you have a lot of legacy equipment, you might find the port selection a bit sparse. It focuses heavily on modern digital connections, so check your device compatibility before purchasing.
Customer Reviews Analysis
Taking a look at the broader sentiment regarding the Signa S4, it consistently ranks well for users looking for a “plug-and-play” solution. Many customers echo my experience regarding the ease of setup. It seems the most common praise is directed toward the VoiceAdjust feature, which is a major pain point for many older viewers or those who struggle with modern TV audio mixes.
However, there are some mixed reviews when it comes to the subwoofer performance. Some users feel it is a bit overpowering, while others wish it had a bit more “slam.” This highlights the importance of the BassAdjust settings—it is a feature you really need to play with to find the balance that works for your specific room acoustics.
A few negative reviews point out issues with the HDMI eARC connection. In some instances, users report needing to toggle settings in their TV’s menu to get the soundbar to “handshake” correctly with the TV. This isn’t necessarily a fault of the soundbar itself, but rather a quirk of modern TV compatibility. Overall, the majority of users seem very satisfied with the value-to-performance ratio provided at the $379.00 price point.
Who Should Buy This Product
The Signa S4 is a perfect fit for a specific type of user. You should consider this soundbar if:
You are tired of poor dialogue quality: If you spend half your time watching TV with the subtitles on because you can’t hear what the characters are saying, the VoiceAdjust technology alone makes this purchase worth it.
You want a home theater experience without the hassle: If you don’t have the space or the budget for a 5.1 or 7.1 system with wires running everywhere, this 2.1-channel (with virtualized Atmos) system provides a massive upgrade over TV speakers with minimal effort.
You are a casual to mid-level movie watcher: If you enjoy watching Netflix, Disney+, or Blu-rays and want to feel the impact of a good soundtrack and clear voices, you will be happy with this. If you are an extreme audiophile with a dedicated theater room, you will likely want to look at more expensive, multi-component systems.
You have a newer TV: Because this relies on HDMI eARC for the best performance, it is ideal for those who already own a 4K or 8K TV with an eARC-enabled HDMI port.
Final Verdict
After using the Signa S4 for several weeks, I can confidently say that it is a solid, reliable, and high-performing sound system for the average home. It isn’t going to replace a $2,000 professional home theater system, and it doesn’t try to. Instead, it succeeds exactly where it needs to: it makes television more enjoyable.
The combination of Dolby Atmos immersion, the clarity provided by VoiceAdjust, and the convenience of a wireless subwoofer makes it a great middle-ground option. At $379.00, it sits in a very competitive price bracket, but the build quality and the “set it and forget it” nature of the device make it a compelling choice.
If your goal is to drastically improve your TV’s audio, simplify your setup, and finally hear the dialogue in your favorite shows clearly, the Signa S4 is a fantastic investment. It offers a premium feel and a noticeable improvement in sound quality that will make you wonder how you lived with your TV’s built-in speakers for so long.
