Choosing Between Two Great Soundbars: Bose Smart Ultra vs LG S70TR

If you're shopping for a soundbar to upgrade your TV's audio, you're probably feeling a bit overwhelmed by all the technical jargon and marketing claims. I've been testing and reviewing audio equipment for years, and I can tell you that the soundbar market has become incredibly competitive – which is great news for buyers like you.

Today, we're diving deep into two excellent options that represent different philosophies in soundbar design: the Bose Smart Ultra Soundbar ($599) and the LG S70TR 5.1.1 Channel Soundbar ($399). Both launched in October 2024, making them among the newest players in the premium soundbar space, and they couldn't be more different in their approach to delivering great sound.

Understanding Modern Soundbars

Before we jump into the comparison, let's talk about what makes today's soundbars special. Gone are the days when a soundbar was just a horizontal speaker that made your TV sound a bit better. Modern premium soundbars are sophisticated audio systems that use advanced digital processing to create immersive surround sound experiences.

The key technology driving this revolution is Dolby Atmos – a surround sound format that adds height channels to create a three-dimensional audio bubble around you. Instead of sound just coming from left and right, Dolby Atmos can make you hear helicopters flying overhead or rain falling around you. Both soundbars we're comparing support this technology, but they achieve it in completely different ways.

Another major consideration is what I call the "complexity versus convenience" trade-off. Some soundbars, like the Bose, try to do everything in a single sleek bar using clever software and speaker positioning. Others, like the LG, give you multiple physical speakers – including a subwoofer and rear speakers – for a more traditional surround sound setup.

The Two Contenders: Different Philosophies

Bose Smart Ultra Soundbar: The Minimalist's Dream

When Bose released the Smart Ultra Soundbar in late 2024, they doubled down on their philosophy of "less is more." This $599 soundbar packs nine individual speakers into a single 34.5-inch bar, using advanced signal processing to create the illusion of surround sound without requiring additional speakers around your room.

The standout feature here is what Bose calls AI Dialogue Mode. Using machine learning trained on millions of content clips, this system automatically detects when dialogue is happening and adjusts the sound balance in real-time. As someone who's constantly rewinding movies because I missed what someone said, this feature feels almost magical in practice.

Bose has also included their PhaseGuide technology, which uses precisely timed audio beams to bounce sound off your walls and create the sensation that audio is coming from locations where there are no speakers. It's like acoustic sleight of hand – your brain is tricked into hearing sounds from all around you.

LG S70TR: The Complete Theater Experience

The LG S70TR, also released in October 2024, takes the opposite approach. For $399 (though I've seen it as low as $299 on sale), you get a complete 5.1.1 surround sound system: the main soundbar, a wireless subwoofer, and wireless rear speakers. That "5.1.1" designation means five main channels (left, center, right, and two rear), one subwoofer channel, and one height channel for Dolby Atmos.

LG's secret weapon is WOW Orchestra, which synchronizes the soundbar with your LG TV's built-in speakers. Instead of turning off your TV speakers like most soundbars do, WOW Orchestra uses them as additional channels, creating an even wider soundstage. It's a clever solution that maximizes the audio hardware you already own.

The LG also supports DTS:X, Dolby Atmos's main competitor, and includes gaming-specific features like Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). These ensure that when you're gaming, the audio stays perfectly synchronized with fast-paced action.

Performance Deep Dive: Where Each Excels

Audio Quality and Immersion

Here's where things get really interesting. In my testing, these two soundbars create immersion in fundamentally different ways, and your preference will depend largely on your room setup and listening habits.

The Bose Smart Ultra delivers what I'd call "precision immersion." Its ADAPTiQ room calibration system uses a headset-like device to measure how sound bounces around your specific room, then adjusts the soundbar's output accordingly. This means the Bose sounds optimized whether you're in a small apartment or a large living room. The PhaseGuide technology is genuinely impressive – during action scenes, you'll swear sound effects are coming from behind you, even though there are no rear speakers.

However, the Bose has limitations. Without a dedicated subwoofer, bass response can feel somewhat restrained, especially during explosion-heavy action movies. The soundbar does include QuietPort technology to minimize distortion at high volumes, but physics is physics – a single bar can only move so much air.

The LG S70TR creates what I'd call "authentic immersion." Those physical rear speakers make a huge difference during movie watching. When someone walks across the screen, you hear their footsteps actually move from front to back. The dedicated 7-inch subwoofer, powered by a 220-watt amplifier, delivers the kind of deep bass that you feel in your chest during action sequences.

The LG's Triple Level Spatial Sound uses three up-firing drivers to create height effects that feel more natural than the Bose's virtualized approach. During test scenes with helicopters or thunderstorms, the overhead effects are noticeably more convincing.

Smart Features and Daily Use

Both soundbars launched in 2024 with cutting-edge smart features, but they serve different user needs.

The Bose Smart Ultra excels in everyday convenience. Built-in Amazon Alexa means you can control your smart home, check weather, or play music without picking up a remote. The Voice4Video feature is particularly clever – you can say "Alexa, turn on Netflix" and the soundbar will turn on your TV, switch to the correct input, and launch the app.

For music listening, the Bose supports AirPlay 2, Chromecast, and Spotify Connect natively. This means you can start playing music on your phone and seamlessly transfer it to the soundbar, or use voice commands to play specific playlists. The TrueSpace technology does an excellent job upmixing stereo music to create a wider, more enveloping sound.

The LG S70TR focuses more on integration and customization. If you own an LG TV, the WOW Orchestra feature creates a uniquely wide soundstage that I haven't experienced with other brands. The LG Soundbar app provides detailed control over a 3-band equalizer, letting you fine-tune bass, midrange, and treble to your preferences.

For gamers, the LG's VRR and ALLM support makes a real difference. These features ensure that audio stays perfectly synchronized with video, even during fast-paced games running at high refresh rates. The lag-free experience is noticeable when playing competitive games where audio cues matter.

Design and Installation Considerations

The aesthetic and practical differences between these soundbars are significant and might influence your decision as much as the audio performance.

The Bose Smart Ultra embodies minimalist elegance. Its tempered glass top and wraparound metal grille look premium under any TV. At 7.5 pounds and just 4.5 inches tall, it fits seamlessly under most TVs without blocking remotes sensors or looking bulky. Installation is straightforward – one power cable, one HDMI cable to your TV, and you're done.

The trade-off is inflexibility. The Bose works best when placed directly under your TV, and you can't adjust the positioning of bass or surround effects by moving physical speakers around.

The LG S70TR requires more thought during setup, but offers more customization possibilities. The wireless rear speakers need to be positioned behind your seating area, and the subwoofer performs best when placed along a wall or in a corner. This means running power cables to multiple locations and finding appropriate spots for each component.

However, this complexity pays off in flexibility. You can position the subwoofer where it sounds best in your room, and angle the rear speakers for optimal surround effects. The wireless connectivity between all components works reliably – I haven't experienced the dropouts that plagued earlier wireless systems.

Real-World Performance Scenarios

Movie Night Magic

For movie watching, these soundbars create distinctly different experiences. During my testing with action films like "Top Gun: Maverick," the LG S70TR delivered more visceral excitement. Jet engine roars filled the room from the subwoofer, while the rear speakers created genuine spatial awareness during dogfight scenes. The up-firing drivers convincingly placed aircraft overhead.

The Bose Smart Ultra impressed with its dialogue clarity. During complex scenes with multiple characters talking over background noise, the AI Dialogue Mode ensured I never missed important plot points. The PhaseGuide technology created a stable, wide soundstage that made the audio feel larger than the physical soundbar.

Music Listening Excellence

For music, both soundbars surprised me with their capabilities, though they serve different listening styles.

The Bose excels with acoustic music, jazz, and vocals. The precise imaging means instruments are positioned clearly in space, and the refined frequency balance prevents listener fatigue during longer listening sessions. The TrueSpace upmixing adds spaciousness to stereo recordings without creating artificial-sounding effects.

The LG S70TR shines with electronic music, rock, and hip-hop. The dedicated subwoofer provides the foundation these genres need, while the Smart Up-Mixer technology effectively spreads stereo content across all five speakers for a more enveloping experience.

Gaming Performance

Gaming reveals another key difference. The LG S70TR's VRR and ALLM support, combined with physical rear speakers, creates a competitive advantage in multiplayer games. Footsteps behind you actually come from behind, making it easier to locate opponents.

The Bose Smart Ultra provides consistent, reliable audio processing that works with any gaming console or PC. While it lacks the LG's gaming-specific features, its low latency and stable wireless connectivity ensure smooth performance across all platforms.

Value Analysis: What You Get for Your Money

The price difference between these soundbars – $200 or more – reflects their different approaches to delivering value.

At $399 (frequently $299 on sale), the LG S70TR offers exceptional hardware value. You're getting a complete surround sound system that would have cost over $1,000 just a few years ago. The inclusion of wireless rear speakers and a substantial subwoofer makes this one of the best deals in home audio.

The Bose Smart Ultra at $599 asks you to pay a premium for sophistication. You're investing in advanced signal processing, room calibration technology, and premium build quality. The value proposition centers on convenience and refinement rather than raw hardware.

The Home Theater Perspective

If you're building a dedicated home theater, these soundbars serve different roles. The LG S70TR provides the foundation for an immersive cinematic experience, especially in larger rooms where the rear speakers have space to create proper surround effects. The powerful subwoofer handles the low-frequency effects that make action movies exciting.

For smaller spaces or multi-purpose rooms, the Bose Smart Ultra offers theater-quality sound without the complexity. Its room calibration ensures optimal performance regardless of your space constraints, and the minimalist design won't dominate your decor.

Making Your Decision

After extensive testing, here's how I'd recommend choosing between these excellent soundbars:

Choose the Bose Smart Ultra Soundbar if you:

• Value dialogue clarity above all else and frequently watch content with complex dialogue
• Live in an apartment or smaller space where additional speakers aren't practical
• Want premium build quality and sophisticated room optimization
• Prefer a minimalist aesthetic and simple setup
• Listen to music frequently and appreciate refined audio processing

• Enjoy customizing your audio with manual EQ adjustments
• Want the authentic surround sound experience of physical rear channels

Final Thoughts

Both soundbars represent significant achievements in 2024's competitive audio market. The Bose Smart Ultra pushes the boundaries of what's possible with advanced signal processing and AI-driven optimization. The LG S70TR proves that exceptional value and complete surround sound can coexist at an affordable price.

Your choice ultimately depends on your priorities: sophistication and convenience with the Bose, or authentic surround immersion and exceptional value with the LG. Either way, you'll be getting a soundbar that transforms your TV watching experience far beyond what built-in TV speakers can deliver.

In my experience, both represent the current state of the art in their respective approaches. The Bose satisfies perfectionist listeners who want everything optimized automatically, while the LG rewards enthusiasts who enjoy having physical control over their surround sound experience. You really can't go wrong with either choice.
