Devialet Dione vs JBL Bar 700: Which Premium Soundbar Should You Buy?

Shopping for a premium soundbar in 2024 feels overwhelming. You're bombarded with technical jargon like "Dolby Atmos," "eARC," and "driver arrays" without clear explanations of what actually matters for your living room. The truth is, most soundbars promise cinema-quality audio, but few deliver on that promise in meaningfully different ways.

Two soundbars stand out for taking completely different approaches to premium audio: the Devialet Dione and the JBL Bar 700. One represents audiophile engineering compressed into a single, elegant unit. The other offers a comprehensive wireless system with components you can optimize for your space. At the time of writing, these products sit at dramatically different price points—the Devialet Dione costs nearly three times more than the JBL Bar 700—yet both target discerning buyers who want exceptional sound quality.

Understanding which approach suits your needs requires diving into what makes premium soundbars actually premium, and more importantly, which technical advantages translate to real-world benefits in your home.

Understanding What Makes Soundbars Premium

The soundbar market splits into clear categories. Budget models under $200 simply make TV audio louder. Mid-range options around $300-600 add basic surround effects and wireless subwoofers. Premium soundbars, however, attempt to recreate the cinema experience through sophisticated audio processing, high-quality components, and immersive technologies.

Dolby Atmos represents the current gold standard for immersive audio. Unlike traditional 5.1 surround sound that places audio in specific channels (front left, center, right, surrounds, and subwoofer), Atmos treats sounds as "objects" that can be precisely positioned in three-dimensional space, including overhead. When a helicopter flies across the screen, Atmos can make that sound move smoothly above your head rather than jumping between discrete speakers.

The challenge lies in implementation. True Atmos requires physical height channels—speakers pointed upward or positioned overhead. Most soundbars fake this effect through "virtualization," using psychoacoustic tricks to fool your brain into perceiving overhead sound from drivers pointed forward. The results vary dramatically between products.

Driver quality and amplification separate good soundbars from great ones more than marketing features. High-quality drivers (the actual speakers) reproduce sound with less distortion, better frequency response, and higher dynamic range. Amplifier design affects how cleanly and powerfully those drivers perform. Premium soundbars invest heavily in both areas.

Bass reproduction poses particular challenges. Deep, impactful bass requires moving lots of air, which typically demands large drivers in substantial enclosures. Soundbars must balance bass performance with sleek aesthetics and practical size constraints. This often leads to compromises that external subwoofers address.

The Devialet Dione Approach: Audiophile Engineering in One Box

Released in 2022, the Devialet Dione represents Devialet's attempt to compress their high-end audio expertise into a practical soundbar format. Devialet built their reputation creating $3,000+ wireless speakers that compete with reference-grade hi-fi systems. The Dione brings that engineering philosophy to home theater.

Revolutionary Driver Array Design

The Dione's most significant innovation lies in its 17-driver configuration. Most soundbars use 6-10 drivers total; the Dione packs 9 full-range aluminum drivers handling mids and highs, plus 8 dedicated long-throw aluminum subwoofers for bass reproduction. This isn't just about numbers—it's about specialization.

Each driver type optimizes for specific frequency ranges. The full-range drivers feature aluminum domes with neodymium magnets, delivering crisp highs and detailed midrange without the harshness common in cheaper tweeters. The eight subwoofer drivers use a "push-push" configuration where opposing drivers cancel each other's vibrations, eliminating cabinet resonance while generating substantial bass output.

This design eliminates the need for an external subwoofer—a remarkable achievement in a soundbar measuring just 47 inches long. The Dione reaches down to 24Hz, deeper than many dedicated subwoofers, while maintaining the clean aesthetics of a single component.

Advanced Amplification Technology

Devialet's ADH (Analog Digital Hybrid) amplification distinguishes the Dione from conventional soundbar designs. Most audio equipment uses either Class A (pure but inefficient) or Class D (efficient but sometimes harsh) amplification. ADH combines both approaches: a Class A stage defines the signal's character while Class D stages provide the power, resulting in both purity and efficiency.

This technology, embedded in Devialet's custom Intelligence Processor chip, delivers measured distortion levels around 0.001%—essentially inaudible. Combined with 950 watts of total amplification, the Dione can reach 101dB at one meter without losing clarity, loud enough to satisfy even the most demanding home theater enthusiasts.

The ORB: Solving Center Channel Challenges

The Dione's rotating ORB center channel solves a real problem. Soundbar center channels typically point straight forward, which works fine when placed on furniture but becomes problematic when wall-mounted. The ORB mechanically rotates 180 degrees, ensuring the center channel—critical for dialogue clarity—always aims toward the listening position regardless of mounting orientation.

This mechanical solution works alongside advanced digital processing. The soundbar automatically detects its orientation and adjusts channel mapping accordingly, maintaining consistent surround and height effects whether horizontal on a TV stand or vertical on a wall.

True Dolby Atmos Implementation

Unlike most soundbars that virtualize Atmos effects, the Dione implements true 5.1.2 processing with dedicated height channels. Four upward-firing drivers create genuine overhead effects rather than relying on psychoacoustic tricks. Combined with Devialet's ADE (Advanced Dimensional Experience) beamforming technology, the result approaches discrete speaker systems for immersion.

The Dione's SPACE algorithm also upmixes stereo content into convincing 5.1.2 presentations, transforming regular TV broadcasts and streaming content into immersive experiences. This works particularly well for music, where subtle spatial cues enhance the listening experience without destroying the original artistic intent.

The JBL Bar 700 Approach: Comprehensive Wireless Flexibility

JBL released the Bar 700 in 2023, incorporating lessons learned from years of soundbar development. Rather than cramming everything into one enclosure, JBL embraces a multi-component approach that prioritizes flexibility and user convenience while maintaining strong performance.

Detachable Wireless Surround Strategy

The Bar 700's most innovative feature involves its detachable wireless surround speakers. These compact units attach to the main soundbar for charging and storage, then detach for placement behind the listening position. Each surround speaker contains a full-range driver and 10-hour battery, eliminating wire routing while providing genuine rear-channel effects.

This approach solves real-world problems. Many users avoid traditional surround systems due to wire management challenges, especially in rental properties or rooms where permanent installation isn't practical. The Bar 700's wireless surrounds provide authentic 5.1 surround without infrastructure requirements.

When not in use, the surround speakers magnetically attach to the main bar, maintaining a clean appearance while keeping batteries topped off. This seamless integration between stored and deployed configurations shows thoughtful product design.

Dedicated Wireless Subwoofer

The Bar 700 includes a substantial 10-inch wireless subwoofer with 300 watts of dedicated amplification. While this requires finding floor space for an additional component, it offers placement flexibility that single-unit designs cannot match. Optimal subwoofer positioning often differs from optimal soundbar placement, and the wireless connection enables experimentation to find the best bass response in your specific room.

The subwoofer extends frequency response down to 35Hz, covering most movie content effectively. While not quite as deep as the Dione's 24Hz capability, it provides satisfying impact for action movies and music without overwhelming smaller rooms.

PureVoice Dialogue Enhancement

JBL's PureVoice technology addresses a common complaint about modern movies: muddy dialogue during action sequences. This algorithm analyzes incoming audio and dynamically adjusts the frequency response to maintain dialogue clarity even when explosions and music compete for attention.

During our research into user experiences, dialogue clarity emerged as the Bar 700's strongest attribute. The combination of PureVoice processing and a dedicated center channel driver delivers consistently intelligible speech across various content types, from whispered conversations to chaotic battle scenes.

Room Correction and Calibration

The Bar 700 includes automatic room correction that analyzes your space's acoustic characteristics and adjusts the system's response accordingly. Using an embedded microphone, it measures how sound reflects off walls, furniture, and other surfaces, then applies corrective equalization to optimize performance for your specific environment.

This feature proves particularly valuable given the system's multi-component nature. The room correction accounts for subwoofer and surround speaker placement, ensuring balanced sound regardless of how you configure the system in your space.

Performance Deep Dive: Where Each Excels

Audio Quality and Clarity

Based on extensive research into professional measurements and user experiences, the Devialet Dione demonstrates superior overall audio quality. Its 950-watt ADH amplification system and 17-driver array deliver exceptional clarity across all frequencies, with distortion levels that approach high-end separate components.

The Dione's aluminum drivers reproduce detail and nuance that cheaper drivers miss entirely. Instrument separation in complex musical passages remains distinct, and vocal reproduction exhibits natural timbre without artificial enhancement. This technical superiority becomes most apparent during critical listening sessions or when playing reference-quality content.

The JBL Bar 700, while not matching the Dione's absolute fidelity, provides excellent clarity for its price category. Its 620-watt total amplification and thoughtfully designed driver complement deliver clean, engaging sound that satisfies most listeners' expectations for premium audio.

Bass Performance Comparison

Bass reproduction represents perhaps the most significant performance difference between these systems. The Dione's eight integrated subwoofers generate remarkable low-frequency output for a single enclosure, reaching true sub-bass frequencies that you feel as much as hear. The push-push driver configuration eliminates unwanted vibrations while maximizing output, creating bass that rivals dedicated subwoofer systems.

During action movie sequences, the Dione reproduces the full impact of explosions and crashes without the boomy, one-note character common in soundbar bass. The integration between bass and midrange frequencies remains seamless, maintaining dialogue clarity even during intense low-frequency effects.

The Bar 700's dedicated subwoofer provides substantial bass impact with the flexibility of optimized placement. While not extending quite as deep as the Dione, it delivers satisfying performance for most content. The wireless connection enables experimentation with subwoofer positioning to minimize room modes and maximize impact.

For bass enthusiasts, the Dione offers superior performance, but the Bar 700's approach provides adequate impact with greater flexibility for fine-tuning.

Surround Sound and Immersion

The approaches to surround sound create fundamentally different experiences. The Dione's true Dolby Atmos implementation with dedicated height channels creates more convincing overhead effects than virtual processing can achieve. When watching Atmos-encoded content, helicopters genuinely seem to pass overhead, and ambient effects place you within the scene rather than in front of it.

The Bar 700's combination of virtual Atmos processing and physical surround speakers provides excellent horizontal surround effects with adequate height simulation. The wireless surround speakers create genuine rear-channel ambience that single-unit soundbars cannot match, improving immersion for traditional 5.1 content.

For pure Atmos performance, the Dione excels. For overall surround immersion across various content types, the Bar 700's physical surround speakers provide advantages that virtual processing cannot fully replicate.
