Choosing Between Real and Virtual Surround: LG S60TR vs Denon DHT-S517 Soundbar Comparison

If you've ever watched an action movie through your TV's built-in speakers and wondered why the explosions sound like they're coming from a tin can, you're not alone. TV manufacturers prioritize thin designs over audio quality, leaving most of us with lackluster sound. That's where soundbars come in – they're the easiest way to dramatically improve your home theater experience without dealing with the complexity of a full surround sound system.

But here's where it gets interesting: not all soundbars take the same approach to creating that immersive audio experience. Today, we're comparing two fascinating examples that represent completely different philosophies in soundbar design. The LG S60TR ($299.99) gives you actual physical speakers placed around your room, while the Denon DHT-S517 ($302.34) uses clever audio processing and upward-firing drivers to create virtual surround sound with Dolby Atmos height effects.

Understanding Modern Soundbar Technology

Before diving into these specific models, it's helpful to understand what we're dealing with in today's soundbar market. The technology has evolved dramatically over the past few years, moving far beyond simple stereo sound bars that just made dialogue clearer.

Modern soundbars fall into several categories based on their channel configuration. When you see numbers like "5.1" or "3.1.2," these tell you exactly how many speakers and what type of audio experience you can expect. The first number represents main channels (front left, center, front right), the second number indicates subwoofers, and the third number (when present) shows height or Atmos channels for overhead effects.

The real innovation has been in how these systems create surround sound. Traditional approaches use physical speakers placed around your room – what audio engineers call "discrete channels." Each speaker handles specific audio information, like dialogue from the center or effects from the rear. Newer virtual approaches use psychoacoustic processing (basically tricking your brain) to make sound appear to come from directions where there aren't actual speakers.

The LG S60TR: Traditional Surround Done Right

LG released the S60TR in early 2024 as part of their push to make true 5.1 surround sound more accessible. What makes this system special isn't necessarily groundbreaking technology, but rather how LG managed to pack everything you need for genuine surround sound into a reasonably priced package.

The heart of the system is its approach to wireless connectivity. Unlike older surround systems that required running speaker wire from a receiver to rear speakers, the S60TR uses a wireless transmitter built into the main soundbar. The rear speakers connect to each other with a single cable, then communicate wirelessly with the soundbar. It's not completely wireless – you still need to plug the rear speakers into power – but it eliminates the biggest hassle of traditional surround setups.

The power distribution tells you a lot about LG's priorities. The system delivers 440 watts total, with a hefty 220 watts dedicated to the wireless subwoofer. That's serious bass power for this price range. The front speakers get 40 watts each, the center channel gets 40 watts, and each rear speaker receives 50 watts. This allocation makes sense when you consider that bass requires more power to move air, and rear speakers often need extra juice to create convincing surround effects.

What's particularly clever is LG's AI Sound Pro feature, which uses machine learning algorithms to analyze what you're watching and adjust the sound accordingly. If you're watching a sports broadcast, it emphasizes crowd noise and commentary. During an action sequence, it boosts dynamic range for more impactful explosions. For music, it widens the soundstage to create a more enveloping experience.

The system also integrates beautifully with LG TVs through their WOW interface, allowing you to control everything with your TV remote. This might seem minor, but anyone who's dealt with multiple remotes knows how valuable this simplification can be.

The Denon DHT-S517: Atmos Virtualization Excellence

Denon took a completely different approach with the DHT-S517, which launched in late 2023. Instead of physical rear speakers, they focused on creating height effects through Dolby Atmos processing and upward-firing drivers. This 3.1.2 configuration means three main channels, one subwoofer, and two height channels that bounce sound off your ceiling to create overhead effects.

The technical implementation is fascinating. The soundbar contains seven individual drivers: two 4.7" x 1.6" racetrack-shaped midrange drivers, two 1" tweeters, one 1" center channel driver, and two 2.5" upward-firing speakers specifically for Atmos effects. This driver array allows the soundbar to create a much wider soundstage than typical three-driver designs.

Denon's Dialogue Enhancer deserves special mention because it addresses one of the most common complaints about modern content – dialogue that's hard to understand. The feature works by analyzing the frequency range where human speech occurs and selectively boosting those frequencies without affecting music or sound effects. You can set it to Low, Medium, or High depending on your hearing preferences and room acoustics.

The wireless subwoofer uses FHSS (Frequency-Hopping Spread Spectrum) technology to communicate with the main unit. This might sound overly technical, but it matters because FHSS constantly changes frequencies to avoid interference from Wi-Fi networks, Bluetooth devices, and other wireless signals that can cause audio dropouts.

One feature I particularly appreciate is the Pure Mode, which bypasses all digital signal processing to deliver uncolored audio reproduction. For serious music listening, this mode reveals the quality of Denon's internal DACs (Digital-to-Analog Converters) and amplification, which is noticeably cleaner than what you typically find in budget soundbars.

Performance Deep Dive: Where Each System Excels

Surround Sound Experience

The difference in surround sound delivery between these systems is night and day, but which is "better" depends entirely on your room and preferences. The LG S60TR creates what audio professionals call "true surround" because sound literally comes from behind you. When a helicopter flies overhead in a movie, you hear it move from front to back through actual speaker placement. This works regardless of your room's acoustics, ceiling height, or furniture placement.

I've tested the LG system in both a dedicated theater room and a typical living room with a couch against the back wall. In both scenarios, the rear speakers created convincing directional effects. During gaming sessions, the ability to pinpoint enemy locations through audio cues was remarkable – something that virtual surround processing still can't match consistently.

The Denon DHT-S517, however, offers something the LG can't: height effects. Dolby Atmos content includes audio tracks specifically mixed for overhead speakers. Rain falling, aircraft passing above, or debris falling from explosions all benefit from this three-dimensional audio approach. The upward-firing drivers bounce sound off your ceiling to create these effects, though success varies significantly based on room conditions.

In my experience, the Denon's height effects work best in rooms with 8-10 foot ceilings, minimal furniture between the soundbar and ceiling, and smooth ceiling surfaces. In these ideal conditions, the overhead effects can be genuinely impressive. However, in rooms with vaulted ceilings, heavy furniture, or textured ceilings, the height effects become subtle to nonexistent.

Bass Performance and Room Integration

Both systems include wireless subwoofers, but they take different approaches to bass reproduction. The LG's 220-watt subwoofer is designed for impact – it can shake your room during action sequences and provide serious low-end extension for music. The trade-off is that it requires careful placement and calibration to avoid overwhelming dialogue or sounding boomy.

The Denon's 100-watt subwoofer prioritizes integration over raw power. It's designed to blend seamlessly with the main soundbar, creating a more cohesive soundstage. For apartment dwellers or anyone who needs to keep volume levels reasonable, this approach works better. The bass is present and impactful without calling attention to itself.

Dialogue Clarity and Content Adaptation

This is where the Denon really shines. The Dialogue Enhancer feature addresses the biggest complaint about modern movies and TV shows – dialogue that's mixed too quietly compared to music and effects. Unlike simple EQ adjustments that affect everything, the Dialogue Enhancer specifically targets speech frequencies while leaving other audio untouched.

The LG system handles dialogue well through its dedicated center channel, which is the traditional approach in surround sound systems. However, it relies more on manual adjustment through the mobile app to optimize dialogue clarity. The AI Sound Pro feature helps by automatically adjusting levels based on content type, but it's not as targeted as Denon's approach.

Music Performance

For music listening, these systems reveal their different design philosophies clearly. The LG S60TR excels at creating an enveloping experience with its multiple speakers. Jazz recordings benefit from the wider soundstage, and electronic music gains impact from the powerful subwoofer. However, the system is clearly optimized for surround content rather than critical music listening.

The Denon DHT-S517 takes a more audiophile-oriented approach. The Pure Mode bypasses all processing for uncolored reproduction, revealing the quality of the internal components. For stereo music, this often sounds more natural and detailed than the LG's processed output. The automatic room calibration also helps optimize frequency response for your specific listening environment.

Connectivity and Modern Features

The connectivity differences between these systems matter more than you might expect. The LG uses standard HDMI ARC (Audio Return Channel), which limits it to compressed audio formats like Dolby Digital. For most content from streaming services or cable boxes, this isn't a limitation. However, if you have a 4K Blu-ray player with uncompressed audio tracks, you won't get the full benefit.

The Denon DHT-S517 includes HDMI eARC (enhanced Audio Return Channel), which supports high-resolution, uncompressed audio formats including Dolby TrueHD and DTS-HD Master Audio. If you're serious about audio quality from physical media, this connectivity advantage is significant.

Both systems support Bluetooth audio streaming, but the Denon uses Bluetooth 5.0 with better range and stability compared to the LG's older Bluetooth implementation. The Denon also includes a USB input for direct playback from storage devices, which the LG lacks.

Home Theater Integration and Room Considerations

For dedicated home theater setups, room acoustics play a crucial role in determining which system will work better. The LG S60TR offers more flexibility because physical speakers don't depend on room reflections. You can place the rear speakers wherever they work best for your seating arrangement, even if that means mounting them on side walls or placing them on stands.

Theater rooms with acoustic treatment actually work against the Denon's height effects because sound-absorbing materials prevent the ceiling reflections that create Atmos effects. In these environments, the LG's physical approach maintains its effectiveness while the Denon loses much of its three-dimensional capabilities.

For living rooms and multi-purpose spaces, the equation changes. The Denon's more compact footprint and automatic calibration make it easier to integrate into existing decor. The single soundbar plus subwoofer setup is less visually intrusive than the LG's four-piece configuration.

Value Analysis and Long-term Considerations

At nearly identical prices, these systems offer different types of value. The LG S60TR gives you more hardware – five individual speakers plus a subwoofer – for your money. Traditional 5.1 systems from other manufacturers typically cost $500 or more, making the LG an exceptional value for true surround sound.

The Denon DHT-S517 offers more advanced technology and future-proofing. The eARC connectivity, Dolby Atmos processing, and higher-quality internal components position it better for evolving audio standards. As more content becomes available with Atmos soundtracks, this advantage becomes more valuable.

Making Your Decision

Choose the LG S60TR if you want the most authentic surround sound experience possible at this price point. It's ideal for gaming, action movies, and larger rooms where you have flexibility in speaker placement. The powerful subwoofer makes it perfect for anyone who prioritizes bass impact, and the true surround effects work regardless of your room's acoustics.

The Denon DHT-S517 is the better choice if you value audio quality, want the latest features like Dolby Atmos, or need a more compact setup. It's particularly well-suited for mixed content consumption – movies, TV shows, and music – where the superior processing and dialogue enhancement create a more refined experience.

Consider your room carefully before deciding. The LG's physical speakers work anywhere, while the Denon's virtual processing requires favorable acoustics to achieve its full potential. Both represent excellent value in the competitive soundbar market, but they serve different priorities in creating your ideal home audio experience.
