LG S95TR: Detailed Review
The LG S95TR represents LG’s flagship soundbar offering, and it arrives with a genuinely compelling headline feature: the world’s first up-firing center channel in a consumer soundbar.
This 9.1.5-channel system is engineered to deliver exceptional spatial audio while integrating seamlessly with LG’s OLED television lineup.
Key Features
Triple Up-Firing Speakers with Center Channel Innovation The S95TR’s most distinctive technical achievement is its triple up-firing speaker array, which includes an up-firing center channel — a feature LG claims is an industry exclusive.
Traditional soundbars push dialogue through a front-facing center channel, which can sometimes feel disconnected from on-screen action.
By adding an upward-firing element to the center channel, LG creates a more cohesive, height-aware dialogue experience that anchors voices to the screen with greater precision.
WOWCAST Built-In Wireless Audio Rather than relying on a separate dongle or adapter, the S95TR features WOWCAST technology built directly into the unit.
This enables a completely wireless connection between compatible LG TVs and the soundbar, transmitting Dolby Atmos and DTS:X audio without any perceptible lag or quality degradation.
The result is a cleaner installation with no visible HDMI cables running between your TV and soundbar.
WOW Orchestra and WOW Interface LG’s ecosystem integration features are genuinely impressive.
WOW Orchestra combines the audio output of both your LG TV’s built-in speakers and the soundbar simultaneously, creating a broader, more enveloping soundstage.
The WOW Interface allows full soundbar control directly from your LG TV remote, eliminating the need to juggle multiple remotes or navigate separate apps.
Gaming Performance For gamers, the S95TR offers Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) support, along with HDMI passthrough at up to 120Hz.
This makes it a genuinely capable gaming audio solution that won’t introduce input lag or disrupt your display’s performance features.
Multi-Platform Smart Integration The S95TR supports both Google Assistant and Amazon Alexa, giving it a slight edge over single-assistant competitors.
Chromecast and AirPlay 2 compatibility means streaming audio from virtually any device is straightforward and reliable.
✅ Pros
- Industry-exclusive up-firing center channel dramatically improves dialogue clarity
- WOWCAST built-in eliminates the need for additional adapters
- Exceptional LG ecosystem integration with WOW Orchestra and WOW Interface
- DTS:X support alongside Dolby Atmos provides broader format compatibility
- Dual voice assistant support (Google Assistant and Alexa)
- Strong gaming credentials with VRR, ALLM, and 120Hz passthrough
- More affordable than the Samsung Q990D at $799.99
- 9.1.5 configuration delivers more up-firing channels than the Q990D
❌ Cons
- Ecosystem features are significantly diminished if you don’t own an LG TV
- 9.1.5 configuration has fewer total front-facing channels than the Q990D’s 11.1.4
- No advanced room calibration system comparable to Samsung’s SpaceFit Sound Pro
- WOW Orchestra requires an LG TV to function
Who Is the LG S95TR Best For?
The S95TR is the clear choice for owners of LG OLED or QNED televisions who want a deeply integrated, premium audio experience.
Its up-firing center channel makes it particularly well-suited for movie enthusiasts who prioritize dialogue clarity and vocal presence.
Gamers who want a high-performance audio system without latency concerns will also find it an excellent match.
If you’re building or upgrading an LG-centric home theater, the S95TR delivers exceptional value at its price point.
Samsung Q990D: Detailed Review
The Samsung Q990D is Samsung’s answer to the question of what a truly complete, out-of-the-box premium soundbar experience should look like.
With an 11.1.4-channel configuration, advanced room calibration, and Samsung’s powerful Q-Symphony ecosystem integration, it makes a strong case for its higher price point.
Key Features
11.1.4-Channel True Dolby Atmos The Q990D’s channel count is its most immediately impressive specification.
Eleven front-facing speakers, one dedicated subwoofer, and four up-firing channels create an extraordinarily dense and layered audio environment.
More front-facing channels mean better stereo separation, more precise audio imaging, and a wider soundstage for music and cinematic content alike.
SpaceFit Sound Pro Room Calibration One of the Q990D’s most practical and technically sophisticated features is SpaceFit Sound Pro.
The system uses built-in microphones and acoustic analysis algorithms to measure your room’s dimensions, reflective surfaces, and acoustic characteristics, then automatically optimizes the audio output accordingly.
This is particularly valuable in rooms with unusual shapes, lots of soft furnishings, or reflective hard surfaces that can distort audio reproduction.
Q-Symphony Ecosystem Integration For Samsung TV owners, Q-Symphony is a transformative feature. Rather than simply replacing your TV’s audio output, Q-Symphony orchestrates both the soundbar’s speakers and the Samsung TV’s built-in speakers to work in concert, creating a unified, optimized multi-speaker array. The result is a more expansive and cohesive soundstage that fills the room more naturally.
Up/Side-Firing Rear Speaker Kit The included rear speaker kit in the Q990D goes beyond simple surround sound.
The rear speakers feature both upward-firing and side-firing drivers, which use your room’s ceiling and walls as reflective surfaces to create a dense, enveloping surround field.
This design approach means the rear audio feels genuinely immersive rather than simply directional.
Adaptive Sound and Game Mode Pro Samsung’s Adaptive Sound technology analyzes content in real time, identifying whether a scene features dialogue, action, music, or ambient sound, and adjusts the audio processing accordingly.
This is particularly useful for late-night viewing when you need voices to remain clear at lower volumes. Game Mode Pro reduces audio latency and optimizes the sound profile specifically for gaming content.
Smart Integration The Q990D features Alexa built-in alongside Chromecast and AirPlay 2 support. While it lacks Google Assistant, the built-in Alexa implementation is robust and deeply integrated into the Samsung smart home ecosystem.
✅ Pros
- 11.1.4-channel configuration delivers the most expansive soundstage in this comparison
- SpaceFit Sound Pro provides automatic, intelligent room calibration
- Q-Symphony creates a genuinely unified speaker ecosystem with Samsung TVs
- Up/side-firing rear speakers create exceptionally immersive surround sound
- Adaptive Sound technology intelligently optimizes audio by content type
- Game Mode Pro provides dedicated, optimized gaming performance
- Alexa built-in with robust smart home integration
- Wireless Dolby Atmos without additional hardware
❌ Cons
- Significantly more expensive at $985.00
- Ecosystem benefits are substantially reduced without a Samsung TV
- No DTS:X support mentioned, limiting format compatibility
- Only single voice assistant (Alexa) compared to LG’s dual-assistant support
- Fewer up-firing channels (4) compared to the LG S95TR (5)
- Higher price may be difficult to justify for non-Samsung TV owners
Who Is the Samsung Q990D Best For?
The Q990D is the premium choice for Samsung TV owners who want the most complete, room-filling audio experience available without building a dedicated AV receiver setup.
Its SpaceFit Sound Pro calibration makes it particularly well-suited for rooms with challenging acoustics.
Music enthusiasts and serious cinephiles who want the widest possible soundstage will appreciate the 11.1.4-channel configuration.
If budget is less of a concern and you’re committed to the Samsung ecosystem, the Q990D is a formidable investment.
Buying Guide: What to Consider Before You Purchase
1. Your Existing TV Ecosystem
This is arguably the single most important factor in this decision. Both soundbars offer their most compelling features when paired with their respective brand’s televisions. The LG S95TR’s WOWCAST, WOW Orchestra, and WOW Interface features require an LG TV to function.
The Samsung Q990D’s Q-Symphony and SpaceFit Sound Pro deliver their best results with a Samsung TV. If you own an LG TV, the S95TR is the natural choice. If you own a Samsung TV, the Q990D makes far more sense.
2. Room Size and Acoustics
For larger rooms or spaces with complex acoustics — high ceilings, open floor plans, lots of hard reflective surfaces, the Samsung Q990D’s SpaceFit Sound Pro calibration and 11.1.4-channel configuration give it a meaningful advantage.
The additional front-facing channels help fill larger spaces more effectively. For medium-sized rooms or dedicated home theater spaces, the LG S95TR’s 9.1.5 configuration with its superior up-firing channel count may actually deliver a more precisely calibrated overhead audio experience.
3. Content Priorities
If movies and television are your primary use case and dialogue clarity is a top priority, the LG S95TR’s up-firing center channel is a genuinely differentiating feature.
If you listen to a lot of music or want the most expansive soundstage for cinematic content, the Q990D’s additional front channels and Adaptive Sound technology provide a broader audio canvas.
4. Gaming Requirements
Both systems offer strong gaming performance, but they approach it differently. The LG S95TR’s VRR and ALLM support with 120Hz passthrough makes it a technically superior choice for next-generation gaming setups.
The Samsung Q990D’s Game Mode Pro is more focused on audio optimization for gaming content rather than display passthrough performance.
5. Budget Considerations
The $185 price difference between these two systems is not trivial. The LG S95TR at $799.99 delivers exceptional value, particularly for LG TV owners.
The Samsung Q990D at $985.00 commands a premium that is genuinely justified by its additional channels and room calibration technology, but only if you’ll actually benefit from those features in your specific setup.
Frequently Asked Questions
Q: Can I use either soundbar with a non-brand TV? Both the LG S95TR and Samsung Q990D will function as standard soundbars with any television via HDMI ARC/eARC or optical connections. However, their most impressive ecosystem features — WOW Orchestra and WOWCAST for LG, Q-Symphony and SpaceFit Sound Pro for Samsung — require pairing with their respective brand’s televisions. You’ll still get excellent Dolby Atmos performance regardless of your TV brand, but you’ll miss the deeper integration benefits.
Q: Which soundbar is better for Dolby Atmos performance? Both systems deliver genuine, high-quality Dolby Atmos performance. The LG S95TR has a slight technical edge in the height channel department with five up-firing speakers (including the innovative center channel), while the Samsung Q990D’s 11.1.4 configuration provides a denser overall channel count. For pure overhead audio immersion, the S95TR’s extra up-firing channel is noteworthy. For overall spatial audio breadth, the Q990D’s higher total channel count is compelling.
Q: Do both soundbars require professional installation? Neither soundbar requires professional installation. Both systems are designed for straightforward consumer setup. The wireless rear speakers and subwoofers in both systems eliminate the most complex wiring challenges. The LG S95TR’s WOWCAST and the Samsung Q990D’s Wireless Dolby Atmos both reduce cable management requirements significantly. Most users report completing setup within 30 to 45 minutes.
Q: Which soundbar performs better for music listening? For music, the Samsung Q990D’s 11.1.4-channel configuration and Adaptive Sound technology generally provide a wider, more detailed stereo image. The additional front-facing channels create better left-right separation and a more natural soundstage for two-channel audio content. The LG S95TR is no slouch for music, but its design optimization leans more toward cinematic surround sound than pure stereo music reproduction.
Q: Are firmware updates available for both products? Yes, both LG and Samsung provide ongoing firmware updates for their premium soundbar lines, delivered wirelessly through their respective smart home apps. These updates can improve performance, add features, and address compatibility issues over time, making both systems solid long-term investments.
Final Verdict
After a thorough analysis of both systems, the right choice comes down to two primary factors: your TV brand and your specific audio priorities.
Choose the LG S95TR if you own an LG television, particularly an OLED model. The WOWCAST integration, WOW Orchestra, and WOW Interface features create a genuinely seamless and impressive ecosystem experience that justifies the purchase on its own.
Add the industry-exclusive up-firing center channel, DTS:X support, dual voice assistant compatibility, and superior gaming credentials, and you have an exceptional soundbar that delivers premium performance at a more accessible $799.99 price point.
Choose the Samsung Q990D if you own a Samsung television and want the most expansive, room-filling audio experience available in a consumer soundbar package.
The 11.1.4-channel configuration, SpaceFit Sound Pro calibration, and Q-Symphony integration represent the current pinnacle of plug-and-play home theater audio.
The $985.00 price is a real consideration, but for Samsung TV owners who want the best possible performance without building a separate AV receiver system, it is money well spent.
If you don’t own either brand’s television, the LG S95TR represents the stronger value proposition, offering more up-firing channels, DTS:X compatibility, and dual voice assistant support at a meaningfully lower price.
Both soundbars are outstanding products that will dramatically improve your home theater experience, but matching your soundbar to your TV ecosystem is the smartest path to getting the most from your investment.
