Budget vs Premium: Finding Your Perfect Soundbar Match

When I first started reviewing audio equipment a decade ago, the soundbar market was pretty straightforward. You had basic models that made your TV louder, and expensive ones that tried to replicate surround sound. Today's landscape is dramatically different, with options spanning from incredibly affordable systems that deliver genuine audio improvements to flagship models that rival dedicated home theater setups.

The Polk Audio Signa S2 and LG S95TR represent two completely different philosophies in this evolution. Released in 2019 and 2024 respectively, they showcase how the soundbar category has matured while also highlighting the fundamental choice every buyer faces: essential upgrade versus premium experience.

Understanding Modern Soundbars: More Than Just Loud TVs

Before diving into these specific models, it's worth understanding what makes a good soundbar and why they've become so popular. Modern TVs, despite their impressive picture quality, have terrible audio. The ultra-thin designs that look great on your wall simply don't have room for decent speakers. That's where soundbars come in.

A soundbar is essentially a long, slim speaker system designed to sit below your TV and dramatically improve audio quality. The "bar" houses multiple speakers pointing in different directions, while many systems include a separate subwoofer (the box that handles deep bass sounds) to round out the experience.

The key specifications that matter most are the channel configuration and supported audio formats. When you see numbers like "2.1" or "9.1.5," they're describing how many speakers the system has. The first number represents main channels (left, right, center), the second is subwoofers, and the third (when present) indicates height or upward-firing speakers for overhead effects.

The Budget Champion: Polk Audio Signa S2

The Polk Audio Signa S2, launched in 2019, represents what I consider the sweet spot for budget soundbar shopping. At the time of writing, it typically costs under $250, making it accessible to most people looking to upgrade their TV audio without breaking the bank.

What Makes the Signa S2 Special

This 2.1 channel system consists of a main soundbar housing four drivers (two oval midrange speakers and two small tweeters) plus a wireless subwoofer with a 5.25-inch driver. While those numbers might not sound impressive compared to premium models, the Signa S2 punches well above its weight class.

The standout feature is Polk's VoiceAdjust technology. This isn't just marketing speak – it's a genuine dialogue enhancement system that boosts vocal frequencies to make conversations in movies and TV shows clearer. Having tested dozens of budget soundbars over the years, I can tell you that clear dialogue is often the biggest improvement people notice when upgrading from TV speakers.

The system supports the basic audio formats you'll encounter: Dolby Digital (the standard surround sound format used by most streaming services and Blu-rays) and DTS, though it downmixes everything to stereo since it only has left and right main channels plus the subwoofer.

Performance Reality Check

In real-world use, the Polk Audio Signa S2 delivers exactly what budget buyers need most: dramatically clearer dialogue and significantly better bass response than any TV can provide. The V-shaped sound signature means it emphasizes both bass and treble while keeping midrange sounds (like voices) clear and present.

The wireless subwoofer is genuinely impressive for the price point. While it can't match the depth and power of premium systems, it adds enough low-frequency impact to make action movies engaging and music more full-bodied. The wireless connection works reliably in my testing, and the subwoofer can be placed anywhere in your room for optimal bass response.

Where the Signa S2 shows its limitations is in soundstage width and surround effects. The audio feels centered around the soundbar itself rather than filling the room, and complex movie soundtracks can sound somewhat flat compared to true surround systems. However, at this price point, those compromises are entirely reasonable.

The Premium Powerhouse: LG S95TR

Jump to 2024, and the LG S95TR represents how far soundbar technology has advanced. This is LG's flagship model, priced at nearly four times the cost of the Signa S2 at the time of writing, but offering capabilities that were unthinkable in budget systems just a few years ago.

Advanced Channel Configuration

The "9.1.5" designation tells an impressive story. This system includes nine main channels: left, right, center, left surround, right surround, left rear surround, right rear surround, plus two additional side channels. The ".1" represents the wireless subwoofer, while the "5" indicates five height channels – speakers that fire upward to bounce sound off your ceiling for overhead effects.

This isn't just about having more speakers; it's about creating a true three-dimensional audio environment. When properly set up, the LG S95TR can place sounds precisely in space around you, whether that's a helicopter flying overhead in an action movie or rainfall surrounding your listening position.

Dolby Atmos and the Height Experience

The biggest technical advancement since the Signa S2's 2019 release has been the mainstream adoption of Dolby Atmos. This audio format treats sounds as objects that can be placed anywhere in three-dimensional space, rather than just sending specific sounds to specific channels.

The LG S95TR's height channels are crucial here. These upward-firing speakers bounce sound off your ceiling to create the impression of audio coming from above. When it works well – and with the right content – it's genuinely impressive. I've tested this with scenes from movies like "Top Gun: Maverick," where jet engines seem to roar overhead, and the effect is remarkably convincing.

Smart Features and Room Calibration

Modern premium soundbars like the S95TR include sophisticated calibration systems. The AI Room Calibration feature uses microphones to analyze your room's acoustics and automatically adjust the sound to compensate for your specific space. This addresses one of the biggest challenges with any audio system: every room sounds different based on size, furniture, and wall materials.

The LG also includes what they call WOW Orchestra, which can coordinate with compatible LG TVs to use the TV's speakers as additional channels. It's a clever way to add even more drivers to the system, though it only works with LG's own televisions.

Performance Deep Dive: Where It Really Matters

Dialogue Clarity: The Most Important Metric

In my experience testing soundbars, dialogue clarity is the single most important performance characteristic for most users. It's the difference between constantly reaching for the remote to adjust volume and simply enjoying your content.

The Polk Signa S2 excels here despite lacking a dedicated center channel. The VoiceAdjust feature genuinely works, boosting vocal frequencies in a way that makes conversations more intelligible without making them sound artificial. I've found this particularly valuable when watching British shows or movies with heavy accents, where every word matters.

The LG S95TR takes a different approach with its dedicated center channel – a speaker specifically designed to handle dialogue. This is the same approach used in high-end home theater systems, and the results are impressive. Voices remain anchored to the screen even during complex action sequences, and the dialogue enhancement features work more subtly than the Signa S2's VoiceAdjust.

Bass Response and Room Filling Capability

Subwoofer performance varies dramatically between these systems, and it's not just about the price difference. The Signa S2's 5.25-inch driver provides sufficient bass impact for most content in small to medium rooms. It can't reproduce the deepest frequencies that you'd get from a larger subwoofer, but it adds enough low-end weight to make movies engaging and music more satisfying.

The LG S95TR includes a much more substantial subwoofer system designed to fill larger spaces. The bass extension goes deeper, and the overall impact is more dramatic. This becomes particularly important with action movies and music where you want to feel the low-frequency effects, not just hear them.

Surround Sound: Virtual vs True Multi-Channel

This is where the fundamental difference between these systems becomes most apparent. The Polk Signa S2 uses digital signal processing to create a virtual surround effect from its stereo configuration. It widens the soundstage somewhat and can create the impression of sounds coming from beyond the physical width of the soundbar, but it's still fundamentally a stereo experience.

The LG S95TR provides true surround sound with discrete rear speakers that can be positioned anywhere in your room. Combined with the height channels, this creates an authentic surround experience where sounds can be precisely placed around your listening position. The difference is immediately apparent with movie content mastered for surround sound.

Home Theater Considerations: Room Size Matters

Your room size and layout significantly influence which system makes more sense. The Polk Signa S2 works well in smaller spaces – apartments, bedrooms, or modest living rooms where the seating position is relatively close to the TV. Its compact design and straightforward setup make it ideal for simple installations.

The LG S95TR really shines in larger spaces where you can properly position the rear speakers and take advantage of the room-filling capabilities. If your seating is more than 8-10 feet from your TV, or if you have a large, open floor plan, the additional power and surround capabilities become much more valuable.

I've found that the height effects in the LG system work best with ceiling heights between 8-12 feet. Too low, and the sound doesn't have space to develop; too high, and the ceiling reflections become less effective.

Setup and User Experience: Simplicity vs Sophistication

The setup experience differs dramatically between these systems. The Polk Signa S2 exemplifies plug-and-play simplicity. You connect one cable to your TV, plug in the power, and you're essentially done. The subwoofer pairs automatically, and the basic remote gives you access to the handful of settings you'll actually use.

The LG S95TR requires significantly more effort to reach its potential. You'll need to position multiple wireless components, run the room calibration routine, and likely spend time in the app adjusting settings. It's not difficult, but it's definitely more involved than budget alternatives.

For some users, this complexity is worthwhile because it allows fine-tuning of the audio experience. For others who just want better TV sound without the hassle, it can be overwhelming.

Value Proposition: What You're Really Buying

At the time of writing, the price difference between these systems is substantial – roughly 4-5 times more for the LG S95TR. This raises the obvious question: is the premium system worth that much more?

The answer depends entirely on your priorities and expectations. The Polk Signa S2 delivers perhaps 80% of the audio improvement most people want from a soundbar upgrade at 20% of the cost of premium alternatives. That's exceptional value if you're primarily looking to improve dialogue clarity and add some bass impact to your TV viewing.

The LG S95TR provides capabilities that simply don't exist at lower price points. True surround sound, height effects, room calibration, and flagship-level build quality justify the premium for users who prioritize audio quality and want a system that can serve as the centerpiece of a serious home theater setup.

Technology Evolution and Future-Proofing

The five-year gap between these products' releases highlights how rapidly soundbar technology has advanced. In 2019, Dolby Atmos was still a premium feature found mainly in high-end systems. By 2024, it's become much more mainstream, though still concentrated in mid-range and premium products.

The LG S95TR includes HDMI 2.1 support with eARC (enhanced Audio Return Channel), which provides higher bandwidth for advanced audio formats and better integration with modern gaming consoles and streaming devices. The Signa S2 uses the older HDMI ARC standard, which is sufficient for current content but lacks some future-proofing capabilities.

Who Should Buy What: Making the Right Choice

Based on my experience with both systems, the decision ultimately comes down to your specific situation and priorities.

Choose the Polk Audio Signa S2 if you're looking for the most significant audio improvement per dollar spent. It's perfect for apartment dwellers, students, or anyone who wants dramatically better TV audio without complexity or high cost. The dialogue enhancement alone makes it worthwhile for people who watch a lot of TV shows or news programming.

The LG S95TR makes sense for dedicated movie enthusiasts with the room and budget to support it. If you're building a proper home theater setup, have a large living space, and want audio that can compete with commercial cinema experiences, the premium system delivers capabilities that justify its cost.

There's no wrong choice here – both products excel in their intended markets. The Signa S2 proves that great audio improvement doesn't require a huge investment, while the LG S95TR demonstrates how sophisticated modern soundbar technology has become.

Your decision should be based on your room size, budget, and how important premium audio features are to your viewing experience. Either way, you'll end up with dramatically better sound than whatever your TV was providing before.
