Choosing Between Two Great Soundbars: Denon DHT-S517 vs JBL Bar 5.1 Surround

When you're tired of constantly adjusting your TV's volume to hear dialogue clearly or missing the rumbling bass in action movies, it's time to consider a soundbar upgrade. But with so many options available, picking the right one can feel overwhelming. Today, we're comparing two popular choices that take very different approaches to solving your TV audio problems: the Denon DHT-S517 and the JBL Bar 5.1 Surround.

Understanding What Makes a Good Soundbar

Before diving into specifics, let's talk about what you should look for in a soundbar. The most important factor is channel configuration – those numbers you see like "3.1" or "5.1" tell you how many speakers are working together. The first number represents main channels (left, center, right), while the number after the decimal indicates subwoofers for bass. Some newer models add a third number for height channels that bounce sound off your ceiling to create overhead effects.

Room size matters tremendously. A powerful soundbar in a small apartment might overwhelm your space, while an underpowered unit in a large living room will leave you straining to hear details. You'll also want to consider what you watch most – dialogue-heavy shows need different tuning than explosive action movies.

The setup complexity varies dramatically between models. Some soundbars work great right out of the box, while others require careful speaker placement and room calibration to sound their best. Your tolerance for setup time and ongoing maintenance should influence your decision.

Meet the Contenders

The Denon DHT-S517, released in 2022, represents Denon's entry into affordable Dolby Atmos soundbars. Dolby Atmos is a surround sound technology that adds height to audio, making you feel like helicopters are actually flying overhead rather than just coming from speakers to your left and right. Denon achieved this at a budget price by using virtual processing and upfiring speakers – small drivers that bounce sound off your ceiling to simulate overhead effects.

The JBL Bar 5.1 Surround takes a different approach entirely. Released around 2020, it focuses on providing true 5.1 surround sound through detachable wireless rear speakers. Instead of relying on digital tricks, you get actual speakers behind your seating position, creating authentic directional audio that moves around the room.

Since their release, the audio landscape has evolved significantly. Newer soundbars often include advanced room correction software that automatically adjusts sound based on your space's acoustics. Wi-Fi connectivity has become standard, enabling integration with smart home systems and multi-room audio setups. However, both of these models have maintained their relevance through strong fundamental performance in their respective approaches.

Surround Sound: Virtual vs. Physical

The biggest difference between these soundbars lies in how they create surround sound immersion. The Denon uses a 3.1.2 configuration with seven total drivers arranged in the main bar. This includes two upfiring speakers that bounce sound off your ceiling to create the impression of height effects. When you're watching a movie and hear rain falling, those upfiring drivers make it seem like the sound is coming from above rather than just from the soundbar.

I've found that virtual surround processing has improved dramatically in recent years, but it still depends heavily on your room's acoustics. If you have high ceilings, textured surfaces, or an open floor plan, the upfiring effects might not work as intended. The Denon compensates with sophisticated digital signal processing that analyzes incoming audio and redistributes it across its seven drivers to create the widest possible soundstage from the front of your room.

The JBL takes the more traditional route with physical surround speakers. The main soundbar handles front and center channels, while two small battery-powered speakers detach and can be placed behind your seating. These rear speakers connect wirelessly and provide up to 10 hours of playback before needing a recharge. When properly positioned, they create genuine directional effects – you'll actually hear footsteps moving from front to back or bullets whizzing past your ears.

In my experience testing both approaches, physical rear speakers always win for pure immersion, especially with action movies and gaming. However, they require more commitment. You need to find good placement spots, remember to charge them periodically, and deal with having extra components in your living space.

Bass Performance: Tight vs. Thunderous

Both soundbars include wireless subwoofers, but their personalities differ significantly. The Denon's 5.25-inch subwoofer with 100 watts of power focuses on tight, controlled bass that integrates well with the main soundbar. It's designed to enhance dialogue clarity while providing enough low-end punch for most content without overwhelming your neighbors.

The JBL's 10-inch subwoofer packs 300 watts and can genuinely shake your room. This subwoofer reaches down to 35Hz – that's the frequency range where you feel bass in your chest during explosive movie scenes. The difference is immediately noticeable when watching action films or listening to bass-heavy music.

However, more powerful doesn't always mean better. In smaller rooms, the JBL's subwoofer can become boomy and muddy if not properly calibrated. The Denon's more modest bass output often integrates more seamlessly with the overall sound signature, creating a balanced presentation that works well for all content types.

The key consideration here is your room size and content preferences. If you're in an apartment or frequently watch dialogue-heavy content, the Denon's approach makes more sense. If you have a larger space and love the visceral impact of movie soundtracks, the JBL delivers experiences the smaller subwoofer simply cannot match.

Dialogue Clarity: Specialized vs. General

One area where the Denon DHT-S517 truly shines is dialogue reproduction. It includes a dedicated Dialogue Enhancer feature with three intensity levels (Low, Medium, High) that specifically boosts voice frequencies without raising the overall volume. This feature proves invaluable during complex movie scenes where explosions and music might otherwise drown out important conversations.

The soundbar's center channel uses a dedicated 1-inch full-range driver optimized for human voice reproduction. Denon also includes a Pure Mode that bypasses all digital processing, providing uncolored audio reproduction that's particularly beneficial for music listening or when you want to hear content exactly as the creators intended.

The JBL relies more on general tuning for dialogue clarity. While it certainly reproduces voices clearly, it lacks the specialized dialogue enhancement features that make the Denon stand out for TV viewing. This isn't necessarily a weakness – the JBL's approach prioritizes overall dynamic range and impact over specialized vocal optimization.

In real-world use, I consistently found myself understanding dialogue better with the Denon, especially during challenging content like British dramas or action movies with complex soundtracks. The JBL required more manual volume adjustment during movies to balance dialogue with sound effects.

Connectivity: Simple vs. Comprehensive

Modern soundbar connectivity extends far beyond just plugging into your TV. The Denon keeps things relatively simple with Bluetooth 5.0 for wireless music streaming, one HDMI input with eARC support (enhanced Audio Return Channel – this lets your TV send audio back to the soundbar through the same HDMI cable), and an optical input for older TVs. There's also a USB-A port for playing music files directly from a flash drive.

The JBL Bar 5.1 Surround offers a much more comprehensive connectivity suite. Beyond Bluetooth, it includes Wi-Fi, AirPlay, Chromecast built-in, and voice assistant compatibility. This enables integration with smart home systems and multi-room audio setups. The JBL also provides three HDMI inputs plus an eARC output, making it easier to connect multiple devices like gaming consoles, streaming boxes, and cable boxes without constantly swapping cables.

For most users, the Denon's simpler approach proves adequate. However, if you're building a connected home theater system or frequently stream music from various devices, the JBL's advanced connectivity becomes valuable. The multi-room capabilities are particularly appealing if you already have other JBL or compatible speakers throughout your home.

Home Theater Performance in Detail

Setting up either soundbar for optimal home theater performance requires different considerations. The Denon works best when placed directly below your TV with clear upward clearance for its height channels. The upfiring speakers need a relatively flat ceiling at reasonable height (8-10 feet works best) to effectively bounce sound back to your listening position.

Room acoustics play a crucial role with the Denon's virtual surround processing. Hard surfaces like tile or hardwood floors help reflect sound, while heavy carpeting and soft furnishings can absorb the reflections that create immersive effects. I've noticed that rooms with cathedral ceilings or unusual layouts often struggle to achieve convincing Atmos effects with upfiring designs.

The JBL requires more deliberate setup but offers greater flexibility once properly configured. The detachable rear speakers should ideally be placed slightly behind and to the sides of your main seating position, elevated about 2-3 feet above ear level. The wireless connection between the soundbar and rear speakers is generally reliable, though I recommend keeping them within reasonable range (about 30 feet) to avoid dropouts.

Both soundbars benefit from proper subwoofer placement, which often requires experimentation. Corner placement typically provides the most bass output, while positioning along a wall offers more balanced response. The "subwoofer crawl" technique – temporarily placing the subwoofer in your listening position and walking around the room to find where bass sounds best – works well with both units.

Music Listening: Different Strengths

While primarily designed for TV audio, both soundbars handle music reasonably well, though with different strengths. The Denon's Music mode widens the stereo image and provides relatively neutral frequency response that works well for various genres. The Pure Mode is particularly valuable for critical music listening, as it eliminates all digital processing that might color the original recording.

The JBL's approach emphasizes dynamics and impact, which works wonderfully for pop, rock, and electronic music but might sound overly aggressive for acoustic or classical content. Its SoundShift technology allows seamless switching between TV audio and Bluetooth music streaming, which proves convenient for parties or casual listening.

Neither soundbar replaces a dedicated stereo system for serious music listening, but both provide significant improvements over TV speakers. The choice between them often comes down to whether you prefer the Denon's more neutral presentation or the JBL's more exciting, bass-forward signature.

Value Considerations and Long-term Ownership

At $302, the Denon DHT-S517 represents exceptional value for Dolby Atmos entry. You're getting premium brand quality, sophisticated processing, and solid build quality at a price point where many competitors offer only basic stereo enhancement. The main trade-offs are the lack of true rear surround channels and limited connectivity options.

The JBL Bar 5.1 Surround costs nearly double but includes hardware that would typically require separate purchases – specifically, those wireless rear speakers that many competing systems charge extra for. When you consider that good wireless surround speakers often cost $200-300 on their own, the JBL's pricing becomes more reasonable.

Long-term ownership differs between the models. The Denon requires minimal maintenance beyond occasional dusting and remains simple to operate. The JBL adds complexity with its detachable speakers that need periodic charging and occasional re-pairing. However, the JBL's modular design also offers more flexibility – you can use just the main soundbar when you don't need full surround, or take the wireless speakers outside for parties.

Both soundbars should provide years of reliable service, but consider your tolerance for maintenance and complexity. The Denon appeals to "set it and forget it" users, while the JBL rewards those willing to engage with its additional features.

Making Your Decision

Choose the Denon DHT-S517 if you prioritize dialogue clarity, want Dolby Atmos effects without rear speaker complexity, or have a smaller room where the more modest bass output fits better. It's also the clear choice if budget is your primary concern or if you prefer simpler operation without ongoing maintenance requirements.

The JBL Bar 5.1 Surround makes sense for larger rooms, movie enthusiasts who want authentic surround immersion, or users who value flexibility and comprehensive connectivity. If you frequently entertain guests or want room-shaking bass for action movies and gaming, the additional investment often proves worthwhile.

Both soundbars represent solid choices in their respective approaches to solving TV audio problems. The Denon excels at providing premium features at an accessible price point, while the JBL offers a more complete surround sound experience for those willing to invest in additional complexity and cost. Your choice should align with your room, content preferences, and how much you're willing to engage with your audio system's setup and maintenance.
