Premium Soundbar Showdown: All-in-One Elegance vs. True Surround Sound

When you're tired of constantly adjusting your TV volume to catch whispered dialogue and then scrambling for the remote when explosions blow out your eardrums, it's time to upgrade to a premium soundbar. But with prices ranging from under $1,000 to well over $2,000, the decisions aren't simple anymore.

Today's premium soundbar market offers two distinct philosophies. On one side, you have elegant all-in-one units like the Devialet Dione that pack everything into a single, beautifully crafted bar. On the other, complete surround systems like the LG S95TR spread discrete speakers around your room for true multi-directional audio. Both approach the same goal – transforming your living room into a home theater – but they get there in completely different ways.

Understanding the Premium Soundbar Landscape

The premium soundbar category has evolved dramatically since 2020. What used to be simple stereo sound bars have transformed into sophisticated audio systems that can rival traditional home theater setups. The key considerations haven't changed much, but the technology behind them has become far more advanced.

Setup complexity remains the biggest differentiator. All-in-one units appeal to people who want great sound without managing multiple components, while modular systems offer better performance at the cost of more complex installation. Audio performance now includes not just how loud something gets, but how well it creates a three-dimensional sound bubble around you using technologies like Dolby Atmos – a format that treats sounds as objects that can be precisely placed anywhere in 3D space around the listener.

Room compatibility has become more critical as soundbars have grown larger and more powerful. Some excel in smaller apartments, while others need substantial space to breathe. Finally, value proposition in this category isn't just about price – it's about whether the performance improvements justify the premium over mid-range options.

The Two Philosophies: Integrated vs. Modular Design

The Devialet Dione, released in 2022, represents the pinnacle of integrated design. This French company, known for their high-end wireless speakers, packed 17 individual drivers into a single 47-inch aluminum bar. The standout feature is the rotating ORB center channel – a spherical speaker that mechanically adjusts its orientation whether you place the bar on furniture or mount it on a wall. This ensures dialogue always fires directly toward your listening position, something most soundbars can't adapt to automatically.

The engineering behind the Devialet Dione is impressive. Those 17 drivers include nine full-range aluminum dome speakers and eight dedicated subwoofers in a "push-push" configuration. This means pairs of woofers face each other and work in opposite directions, canceling out vibrations that would normally shake the cabinet and muddy the sound. The result is clean, powerful bass without needing a separate subwoofer taking up floor space.

The LG S95TR, part of LG's 2024 lineup, takes the opposite approach. This system includes a main soundbar, a wireless subwoofer, and two wireless surround speakers. The "9.1.5" designation means nine main channels at ear level (including left, center, right, and surround positions), one dedicated subwoofer channel, and five height channels that bounce sound off your ceiling to create overhead effects.

What makes the LG S95TR particularly clever is that the surround speakers are completely wireless – no power cords or speaker wires needed. Each surround unit contains three drivers pointing in different directions, creating a more convincing surround bubble than any single soundbar can achieve through acoustic trickery alone.

Audio Performance: Where Physics Meets Perception

Frequency Response and Bass Performance

When evaluating soundbar performance, frequency response – how evenly a system reproduces different pitches from deep bass to bright highs – tells much of the story. The Devialet Dione achieves something remarkable for an all-in-one unit: genuine deep bass extension down to 24Hz. For context, this covers the fundamental frequencies of the largest pipe organs and the deepest movie sound effects. Most soundbars, even expensive ones, start rolling off around 40-50Hz and need a subwoofer to reach these depths.

This impressive bass performance comes from Devialet's SAM (Speaker Active Matching) technology, which continuously monitors and corrects each driver's behavior in real-time. Think of it as having a tiny computer for each speaker that ensures it reproduces exactly what the original recording intended, compensating for the physical limitations of small drivers.

The LG S95TR approaches bass differently. Its dedicated wireless subwoofer can move much more air than any integrated driver, typically resulting in more visceral impact during action scenes. However, this comes with placement considerations – subwoofers work best in specific room positions, and not every living room accommodates this flexibility.

Spatial Audio and Dolby Atmos Performance

Here's where the fundamental differences become most apparent. Dolby Atmos, the latest surround sound format, treats audio as objects that can be placed anywhere in three-dimensional space rather than just specific channels. A helicopter can smoothly move from your front left, overhead, and behind your right shoulder following its path on screen.

The Devialet Dione creates this effect through sophisticated beamforming and psychoacoustic processing. Its ADE (Advanced Dimensional Experience) technology analyzes your room and steers sound waves to create the illusion of sounds coming from positions where no speakers exist. When wall-mounted, this works surprisingly well, creating convincing overhead and surround effects.

However, physics ultimately favors the LG S95TR. Having actual speakers behind and above you means sounds genuinely originate from those locations rather than relying on reflections and audio illusions. The difference is most noticeable in complex scenes with multiple sound sources – discrete speakers provide more precise localization and maintain clarity even when multiple effects play simultaneously.

Dialogue Clarity: The Make-or-Break Factor

Poor dialogue reproduction is the number one complaint about TV audio, and it's often what drives people to upgrade to soundbars in the first place. Both systems address this with dedicated center channels, but their approaches differ significantly.

The Devialet Dione's rotating ORB center channel is more than a gimmick – it's an elegant solution to a real problem. Most soundbars fire sound horizontally regardless of mounting position, but the ORB mechanically adjusts to always aim directly at the listening area. Combined with Devialet's ADH (Analog Digital Hybrid) amplification, which provides extremely clean power delivery, dialogue emerges with exceptional clarity and presence.

The LG S95TR uses more traditional center channel processing but benefits from having more total channels to work with. With dedicated surround speakers handling ambient sounds and effects, the center channel can focus entirely on dialogue without competing for bandwidth or driver resources.

Technical Deep Dive: What Makes Each System Unique

Devialet's Proprietary Technologies

The Devialet Dione incorporates several technologies borrowed from the company's ultra-high-end Phantom speakers. The Intelligence Processor runs four ARM Cortex-A53 processors at 1.25GHz – more computing power than many laptops had a decade ago. This processing muscle enables real-time room correction, advanced upmixing of stereo content to 5.1.2 surround, and the precise timing corrections needed for convincing spatial audio from a single bar.

SPACE technology deserves particular attention. Most soundbars simply play stereo content through their left and right drivers, wasting their multichannel capability. SPACE analyzes incoming stereo music or older TV shows and intelligently redistributes elements across all available channels. Vocals stay centered, ambient sounds spread to the sides, and reverb gets directed to height channels. The result transforms even basic stereo content into an immersive experience.

LG's Meridian Partnership and AI Processing

The LG S95TR incorporates Meridian Horizon technology, a collaboration with the British high-end audio company known for their meticulous attention to sound quality. This partnership shows in the system's more neutral, reference-quality sound signature compared to many consumer-oriented soundbars that boost bass and treble for initial wow factor.

AI Sound Pro represents LG's attempt to solve the "content optimization" problem. Different types of content – action movies, dialogue-heavy dramas, music concerts – benefit from different audio processing approaches. AI Sound Pro analyzes incoming audio in real-time and adjusts the processing accordingly, emphasizing dialogue clarity during conversations and opening up the soundstage during musical performances.

Real-World Performance: How They Handle Different Content

Movie Performance

For blockbuster films with complex Dolby Atmos soundtracks, our research into user experiences reveals interesting patterns. The Devialet Dione excels at creating an impressive wall of sound that works particularly well when wall-mounted. Its integrated bass delivers satisfying impact without overwhelming smaller rooms, and the precise beamforming creates convincing overhead effects during aerial sequences.

However, the LG S95TR provides more convincing surround localization during complex action sequences. When bullets whiz past or vehicles circle the screen, having actual speakers behind you creates a more believable sense of being inside the action rather than watching it from outside.

Music Listening

This is where personal preferences and room acoustics play larger roles. The Devialet Dione includes a dedicated Music Mode that disables spatial processing, creating a more traditional stereo presentation that many audiophiles prefer. The build quality and driver technology shine here – music playback reveals exceptional detail and dynamic range, particularly with high-resolution streaming services.

The LG S95TR offers more flexibility through customizable EQ settings, allowing users to tailor the sound signature to their preferences and room acoustics. The Meridian tuning provides a more neutral starting point that works well across various music genres, though it may lack the distinctive character that makes the Devialet Dione special for critical listening.

Gaming Considerations

Modern gaming often benefits from precise directional audio cues – hearing enemy footsteps from specific directions can provide competitive advantages in multiplayer games. The LG S95TR handles this better due to its discrete surround channels and lower latency processing. The Devialet Dione can exhibit noticeable lip-sync delays, particularly problematic for rhythm games or competitive gaming where timing matters.

Value Proposition: Performance Per Dollar

At the time of writing, the pricing difference between these systems is substantial – the LG S95TR typically costs significantly less than the Devialet Dione while offering more channels and arguably better overall performance for most users. This pricing dynamic reflects different target markets and business philosophies.

The Devialet Dione commands premium pricing through its luxury positioning, proprietary technologies, and exceptional build quality. The anodized aluminum construction and distinctive design make it as much a design statement as an audio device. For buyers who value aesthetics and space efficiency, this premium may be justified.

The LG S95TR represents more traditional consumer electronics value engineering – maximizing performance and features at a competitive price point. The modular design allows for cost optimization while delivering genuine surround sound performance that single-bar systems struggle to match.

Room Considerations and Practical Installation

Small to Medium Rooms (Under 300 square feet)

The Devialet Dione often works better in smaller spaces where its sophisticated processing can effectively fill the room without overwhelming it. The integrated design eliminates placement challenges, and the advanced beamforming can create convincing surround effects even in acoustically challenging rooms with lots of furniture and soft surfaces.

Large Rooms and Open Floor Plans

Bigger spaces typically favor the LG S95TR. Discrete speakers can be positioned optimally around the seating area, and the dedicated subwoofer can pressurize larger volumes of air. The wireless surround speakers solve the biggest challenge in large rooms – getting rear channel information to the back of the space without running cables.

Apartment Living and Shared Walls

Both systems offer volume limiting and night modes, but the Devialet Dione's integrated bass management often works better in apartments where powerful subwoofers can disturb neighbors. The precise driver control allows for satisfying low-frequency reproduction at moderate volumes where separate subwoofers might need to be turned down significantly.

Connectivity and Future-Proofing

Modern premium soundbars must integrate seamlessly with various source devices and streaming services. The LG S95TR offers more comprehensive connectivity, including HDMI passthrough that allows connecting gaming consoles directly to the soundbar while maintaining full 4K HDR video quality to the TV.

The Devialet Dione takes a more minimalist approach with fewer physical connections but comprehensive wireless streaming support. However, its lack of DTS:X support may frustrate users with extensive Blu-ray collections, as many discs use this competing surround format.

Making Your Decision

Choose the Devialet Dione if you prioritize elegant design, space efficiency, and exceptional build quality. Its sophisticated processing creates impressive results from a single unit, and the premium materials and unique ORB design make it a conversation piece. Music lovers who appreciate audiophile-grade reproduction will find much to love, particularly in smaller to medium-sized rooms where its strengths shine brightest.

The LG S95TR makes more sense for most home theater enthusiasts seeking maximum performance and value. The discrete surround speakers provide more convincing spatial effects, the modular design offers placement flexibility, and the comprehensive connectivity ensures compatibility with any source device. If you have space for the components and want the most immersive possible experience, this system delivers more performance for significantly less money.

Both represent the current state of the art in their respective approaches to premium home audio. The choice ultimately depends on whether you value the sophistication and elegance of an integrated solution or prefer the raw performance advantages of discrete components. Either way, you'll be getting a substantial upgrade over basic TV speakers and most mid-range soundbar alternatives.
