Sonos Ray vs. Polk Audio Signa S2: Which Budget Soundbar Should You Choose?

If you've been struggling to hear dialogue clearly on your TV or feel like explosions in action movies lack punch, you're not alone. Most TVs today prioritize slim designs over sound quality, leaving their built-in speakers as an afterthought. That's where budget soundbars come in – they're designed to dramatically improve your audio experience without breaking the bank or requiring complex installations.

Today, we're comparing two popular options that take very different approaches: the Sonos Ray and the Polk Audio Signa S2 with its included wireless subwoofer. Both launched in the early 2020s and represent distinct philosophies in soundbar design. The Sonos Ray, released in 2022, focuses on refined stereo sound and smart home integration. The Polk Audio Signa S2, which hit the market in 2021, delivers a complete 2.1 system (meaning two main channels plus a dedicated subwoofer) right out of the box.

Understanding Budget Soundbars: What Really Matters

Before diving into specifics, let's establish what makes a good budget soundbar. The primary goal is simple: make your TV sound significantly better than it does now. This means clearer dialogue, better overall volume, and ideally some bass improvement to make movies and music more engaging.

The key considerations when shopping in this category include whether you get immediate bass improvement (usually through an included subwoofer), how well the system handles different types of content, and whether it can grow with your needs over time. At the time of writing, quality budget soundbars typically range from under $200 to around $300, making them accessible upgrades for most households.

The Tale of Two Approaches

The Sonos Ray and Polk Audio Signa S2 represent fundamentally different philosophies. Think of the Sonos Ray as the minimalist approach – it's a sleek, single-bar solution that focuses on doing stereo sound exceptionally well. It uses advanced digital signal processing (which is essentially computer-based audio enhancement) to create a wider soundstage than you'd expect from such a compact unit.

The Polk Audio Signa S2, on the other hand, takes the traditional "more is more" approach by including a separate wireless subwoofer. A subwoofer is a specialized speaker designed specifically to handle low-frequency sounds – the rumble of explosions, the thump of bass guitars, and the subtle low-end that gives voices their natural warmth. This means you get immediate and obvious improvement in bass response, which is often what people notice first when upgrading from TV speakers.

Audio Quality: Where Each System Excels

Stereo Imaging and Soundstage

The Sonos Ray really shines when it comes to creating what audiophiles call "soundstage" – the sense that sound is coming from a wider area than just the physical bar itself. Thanks to its sophisticated audio processing and Trueplay room correction technology (a feature that uses your smartphone's microphone to measure your room's acoustics and adjust the sound accordingly), the Sonos Ray can make stereo music and even TV shows sound more spacious and natural.

In my experience testing these systems, the Sonos Ray consistently creates better left-to-right stereo separation. When watching a scene where a character walks across the screen, you can actually hear their footsteps move from one side to the other more convincingly. This might seem like a small detail, but it contributes to a more immersive experience overall.

The Polk Audio Signa S2, while not quite as sophisticated in its stereo imaging, still provides a noticeable improvement over TV speakers. Its two tweeters (high-frequency speakers) and two midrange drivers work together to create decent stereo separation, though it doesn't have the same level of processing refinement as the Sonos Ray.

Bass Performance: The Big Difference

This is where the systems diverge most dramatically. The Polk Audio Signa S2 includes a 5.25-inch wireless subwoofer that immediately transforms your audio experience. Bass isn't just about making things louder – it adds weight and impact to everything from movie soundtracks to music. When a door slams in a thriller or a bassline drops in your favorite song, you feel it as much as hear it.

The Sonos Ray, being a 2.0 system (two channels with no dedicated subwoofer), relies entirely on its built-in drivers for bass. While Sonos has done impressive engineering work to extract reasonable low-end performance from such a compact form factor, it simply can't match the dedicated bass driver of the Polk Audio Signa S2.

If you want to add bass to the Sonos Ray, you'll need to purchase a separate Sonos Sub, which costs significantly more than the entire Polk Audio Signa S2 system at the time of writing. This makes the immediate value proposition quite different between the two systems.

Dialogue Clarity: Two Different Solutions

Both soundbars dramatically improve dialogue clarity compared to TV speakers, but they achieve this through different methods. The Polk Audio Signa S2 features VoiceAdjust technology, which lets you manually boost vocal frequencies. Think of it as a specialized equalizer setting that makes voices cut through background music and sound effects more clearly.

The Sonos Ray takes a more subtle approach, using its room correction technology and carefully tuned frequency response to naturally enhance dialogue without artificial boosting. In practice, both methods work well, though some users prefer having the manual control that the Polk Audio Signa S2 offers.

Volume and Dynamic Range

The Polk Audio Signa S2 can play louder and with more dynamic impact than the Sonos Ray, thanks largely to its dedicated subwoofer. Dynamic range refers to the difference between the quietest and loudest sounds a system can reproduce – and having that separate bass driver means explosive scenes in action movies have more punch and presence.

This doesn't necessarily make the Polk Audio Signa S2 "better" for all users, but it does make it more suitable for larger rooms or for people who like their entertainment loud and impactful. The Sonos Ray is better suited to smaller and medium-sized rooms where its more refined approach can be fully appreciated.

Connectivity: Old School vs. New School

The connectivity options reveal another philosophical difference. The Polk Audio Signa S2 offers multiple physical inputs: HDMI ARC (Audio Return Channel, which lets you control volume with your TV remote), optical digital input, and even a 3.5mm analog input for older devices. This makes it incredibly versatile – you can connect gaming consoles, older Blu-ray players, or even vintage audio equipment.

The Sonos Ray takes a more streamlined approach with just optical input for TV connection, focusing instead on wireless connectivity through Wi-Fi and Apple AirPlay 2. This reflects Sonos's philosophy of wireless-first audio, where your network becomes the primary way to get audio to your speakers.

Both systems support Bluetooth for wireless music streaming, though the Sonos Ray offers more sophisticated streaming options through services like Spotify Connect, which provides higher audio quality than standard Bluetooth.

Smart Features and User Experience

App Control vs. Physical Remote

The Sonos Ray is primarily controlled through the Sonos S2 smartphone app, which offers extensive customization options, equalizer settings, and access to numerous streaming services. The app experience is polished and regularly updated with new features. However, this does mean you'll often need to reach for your phone to make adjustments.

The Polk Audio Signa S2 comes with a traditional infrared remote control, giving you direct access to volume, input selection, and sound modes without needing to unlock your phone or navigate through apps. It's a more immediate, tactile experience that some users strongly prefer.

Room Correction and Setup

The Sonos Ray's Trueplay feature deserves special mention. Using an iOS device (unfortunately, it doesn't work with Android), you can run a room correction process that measures how sound reflects off your walls, furniture, and ceiling. The system then adjusts its audio output to compensate for your room's acoustic characteristics. This can make a significant difference in sound quality, particularly in challenging room layouts.

The Polk Audio Signa S2 doesn't offer room correction, but its wireless subwoofer can be placed anywhere in your room for optimal bass response. This physical flexibility can often achieve similar results to digital room correction, especially for low-frequency performance.

Long-term Value and Ecosystem Considerations

Software Updates and Feature Evolution

Since 2022, the Sonos Ray has received several software updates that have improved its performance and added new features. Sonos has a strong track record of supporting their products with meaningful updates for many years after purchase. This means the soundbar you buy today will likely gain new capabilities over time.

The Polk Audio Signa S2 doesn't receive software updates, but this also means it's not dependent on continued manufacturer support or internet connectivity for its core functionality. It will work the same way years from now as it does today.

Expandability and Growth

The Sonos Ray is designed to be part of a larger ecosystem. You can easily add other Sonos speakers throughout your home for multi-room audio, or upgrade with Sonos surround speakers and subwoofers for a full home theater system. This modular approach means you can start simple and expand over time.

The Polk Audio Signa S2 is more of a complete, standalone solution. While Polk makes other audio products, this particular soundbar doesn't integrate into a broader ecosystem the way Sonos products do.

Real-World Performance: What You'll Actually Notice

Having used both systems extensively, the differences become clear in daily use. The Polk Audio Signa S2 provides immediate "wow factor" – the bass improvement over TV speakers is dramatic and instantly noticeable. Action movies, music with strong basslines, and even the subtle low-end in voices all benefit significantly.

The Sonos Ray offers a more subtle but ultimately more refined improvement. Dialogue clarity is excellent, stereo imaging is impressive for the size, and music playback is genuinely enjoyable. However, the lack of dedicated bass means you'll miss some of the visceral impact that makes movies exciting and music engaging.

For home theater use specifically, the Polk Audio Signa S2 has a clear advantage in terms of immediate impact and excitement. The subwoofer provides the foundation that makes movie soundtracks come alive. The Sonos Ray excels more as a music-focused system that also happens to improve TV audio significantly.

Who Should Choose What

Choose the Sonos Ray if:

You're building for the long term and value audio refinement over immediate impact. If you primarily listen to music, have a smaller room, or plan to eventually expand to a multi-room audio system, the Sonos Ray makes more sense. It's also ideal if you prefer app-based control and appreciate regular software updates.

The Sonos Ray is particularly suited to users who might describe themselves as "audio enthusiasts" – people who notice and appreciate subtle improvements in sound quality and stereo imaging. It's also great for minimalist setups where a single, elegant bar is preferable to multiple components.

Choose the Polk Audio Signa S2 if:

You want maximum immediate impact for your investment. If you watch a lot of action movies, have a larger room, or simply want to feel the bass in your entertainment, the Polk Audio Signa S2 delivers better immediate value. It's also the better choice if you need multiple input options or prefer physical remote control.

The Polk Audio Signa S2 is ideal for families or casual listeners who want a significant, obvious improvement over TV speakers without the complexity of app-based systems or ecosystem planning. It's plug-and-play simplicity with immediate, satisfying results.

The Verdict: Different Strengths for Different Needs

At the time of writing, these soundbars occupy different value propositions despite being in the same general price category. The Polk Audio Signa S2 offers more immediate functionality and dramatic improvement for less money, making it the better choice for most buyers seeking maximum value.

However, the Sonos Ray represents a more sophisticated approach that may provide better long-term satisfaction for users who prioritize audio quality and system integration. Its lack of included bass is a significant limitation, but for the right user in the right room, its strengths can outweigh this compromise.

Ultimately, both soundbars succeed at their primary mission of making TV audio significantly better than built-in speakers. Your choice should depend on whether you prioritize immediate, obvious improvement (the Polk Audio Signa S2) or long-term refinement and expandability (the Sonos Ray). Either way, you'll be getting a substantial upgrade over whatever your TV is producing on its own.
