Premium Soundbar System Guide: TCL Q85H vs LG S90TR - Making the Right Choice

Understanding Modern Premium Soundbars

The home theater landscape has evolved dramatically, with soundbars now offering cinema-quality audio in compact packages. Both the TCL Q85H ($599) and LG S90TR ($796) represent the latest in premium soundbar technology, released in late 2023 and early 2024 respectively. These systems deliver immersive audio through Dolby Atmos and DTS:X - technologies that create three-dimensional soundscapes by precisely placing sounds above and around you.

Modern soundbars have come a long way from simple stereo units. Today's premium models include wireless subwoofers for deep bass, rear speakers for true surround sound, and upward-firing speakers that bounce sound off your ceiling to create height effects. The result can be surprisingly close to a traditional multi-speaker home theater setup, but with much simpler installation.

Core Specifications and Design

The TCL Q85H offers a 7.1.4 channel configuration, meaning seven surround channels, one subwoofer, and four height channels. It packs 15 total speakers into its system. The LG S90TR features a 7.1.3 setup with 13 speakers total, trading one height channel for potentially more refined sound tuning.

Both systems include:

• Wireless subwoofers for deep bass
• Wireless rear speakers for true surround
• HDMI 2.1 with eARC (Enhanced Audio Return Channel)
• Bluetooth 5.1 connectivity
• WiFi streaming capabilities
• Voice assistant compatibility

The physical design of both units focuses on clean lines and minimal visual impact. The TCL measures slightly wider but maintains a low profile that won't block TV screens. The LG offers a more premium feel with its aluminum grille and higher-quality materials.

Sound Performance

Movie Experience

Both soundbars excel at movie playback, but with subtle differences. The TCL Q85H's extra height channel creates a slightly more immersive overhead sound experience, particularly noticeable during scenes with rain or overhead aircraft. The LG S90TR compensates with superior room calibration technology that optimizes sound for your specific space.

For dialogue clarity, the LG edges ahead with its more sophisticated center channel processing. During complex action scenes, both systems maintain clear speech while delivering impactful explosions and effects, though the TCL's subwoofer provides slightly more powerful bass response.

Music Playback

The LG S90TR shows its refinement here with more nuanced handling of musical details. Its AI-powered room calibration helps create a more balanced soundstage, while multiple EQ presets let you optimize for different genres. The TCL Q85H delivers powerful performance with strong bass, though it can sometimes overwhelm mid-range frequencies in complex musical passages.

Both systems support high-resolution audio formats and wireless streaming, but the LG's more advanced processing provides a slight edge for serious music listeners.

Gaming Performance

Modern games demand low latency and precise spatial audio, and both systems deliver. The TCL Q85H's additional height channel creates more precise overhead sound positioning for games that support Dolby Atmos. The LG offers gaming-specific sound modes that emphasize footsteps and directional cues.

Both systems support Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM) through their HDMI 2.1 connections, ensuring synchronized audio with modern gaming systems.

Smart Features and Connectivity

Both soundbars offer comprehensive connectivity options, but implementation differs:

TCL Q85H:

• Simplified setup with TCL TVs
• Basic mobile app control
• Standard streaming options
• Two HDMI inputs

LG S90TR:

• Advanced room calibration
• Sophisticated mobile app
• Wider streaming format support
• Additional sound customization options
• Support for LG WOW Orchestra (combines TV speakers with soundbar)

Setup and Calibration

Initial setup is straightforward for both systems, but the LG's superior room calibration technology provides better automatic optimization. The TCL offers basic calibration but requires more manual adjustment to achieve optimal sound.

Both systems feature wireless rear speakers and subwoofers, eliminating the need for complex wiring. The LG's WOW Orchestra feature, which coordinates with compatible LG TVs, creates an even more immersive experience by utilizing the TV's speakers in conjunction with the soundbar system.

Value Analysis

The TCL Q85H presents compelling value at $599, offering features typically found in more expensive systems. Its extra height channel and powerful bass make it particularly appealing for movie enthusiasts and gamers.

The LG S90TR justifies its higher $796 price tag with superior room calibration, better music performance, and more refined sound processing. Its premium build quality and advanced features appeal to audiophiles and those seeking maximum versatility.

How to Decide

Choose the TCL Q85H if:

• You prioritize value for money
• Movie and gaming performance are your main focus
• You want maximum overhead sound effects
• You have a TCL TV
• Bass impact is a priority

Choose the LG S90TR if:

• Sound refinement is paramount
• You listen to a lot of music
• Room calibration is important
• You have an LG TV
• You want maximum customization options

Final Considerations

Both systems represent excellent choices in the premium soundbar category, but they serve slightly different users. The TCL Q85H offers impressive performance and features at a more accessible price point, while the LG S90TR provides superior refinement and customization for those willing to pay more.

Room size and shape should influence your decision - larger rooms benefit from the TCL's additional height channel and stronger bass, while the LG's superior room calibration might work better in challenging room layouts.

Consider your primary use case carefully. If movies and gaming dominate your entertainment time, the TCL's extra height channel and powerful bass might be preferable. For those who prioritize music or want maximum customization options, the LG's refined sound and advanced features justify its higher price.

Both systems represent significant improvements over previous generations, particularly in wireless connectivity, processing power, and integration with smart home systems. They demonstrate how far soundbar technology has come, offering legitimate alternatives to traditional home theater speaker systems while maintaining the convenience and simplicity that made soundbars popular in the first place.
