Adjust Bass and Treble Settings of LG Soundbars
Bass and treble settings can make a bigger difference than simply increasing the volume. The ideal settings depend on what you’re watching, the size of your room, and your LG soundbar model. The recommendations below are safe starting points that work well for most LG soundbars, including the SH5A, S30A, S40T, S40TR, S65TR, S70TY, S90TY, and S95AR.
Quick Recommendation: For most users, start with Bass: +2 and Treble: +1. This provides deeper bass while keeping dialogue clear. From there, adjust based on your room and personal preference.
Best Bass and Treble Settings for LG Soundbars

| Gaming | +2 to +3 | +1 | Improves explosions, footsteps, and directional sound effects. |

How to Fine-Tune Bass and Treble
If the recommended settings don’t sound perfect in your room, use these simple adjustments:
| Problem | What to Adjust |
|---|---|
| Dialogue sounds muffled | Lower Bass by 1–2 levels or increase Treble by 1 level. |
| Bass is too weak | Increase Bass or Subwoofer level by 1–2 steps. |
| Bass is too boomy | Lower Bass and move the subwoofer away from the corner. |
| Sound feels harsh | Reduce Treble by 1 level. |
| Movies lack impact | Increase Bass slightly and switch to Movie or Cinema Mode. |
| Music sounds flat | Increase both Bass and Treble by 1 level. |
Tips for Models with a Wireless Subwoofer
If your LG soundbar includes a dedicated subwoofer (such as the S70TY, S65TR, S90TY, or S95AR), adjusting the Subwoofer Level usually has a greater impact than increasing the Bass setting.
For most rooms:
- Subwoofer: +2 to +4
- Bass: +2
- Treble: +1
Avoid pushing both the Bass EQ and the Subwoofer level to their maximum values, as this can make dialogue sound muddy and reduce overall clarity.
Expert Tip
Don’t use maximum bass settings. Many users assume that higher bass always sounds better, but excessive bass often masks dialogue and reduces overall sound quality. Start with Bass +2 and adjust gradually until the audio feels balanced..
Tune Rear and Side Speakers of LG Soundbars
Not every LG soundbar includes rear or side speakers. If your model supports wireless rear speakers or an optional surround speaker kit, adjusting the speaker levels can make a noticeable difference to movies, gaming, and music.
The settings below are recommended starting points. You can fine-tune them based on your room size and personal preference.
Recommended Rear & Side Speaker Settings by LG Soundbar Model
| LG Soundbar Model | Recommended Use Case Settings | Notes |
|---|---|---|
| LG S95AR | Movies: Rear/Side +2 to +4, Center +1 to +2, Overhead +1 to +2, Subwoofer +2 to +4 Dialogue/News: Rear/Side 0 to +1, Center +2 to +4, Overhead 0 to +1, Subwoofer -1 to 0 Music: Rear/Side +1 to +2, Center 0 to +1, Subwoofer +1 to +2 Gaming: Rear/Side +2 to +3, Center +1 to +2, Subwoofer +1 to +3 | Full speaker-level adjustment available. Ideal for fine-tuning surround sound in dedicated home theaters. |
| LG S40TR | Movies: Rear +2 to +4 Dialogue/News: Rear 0 to +1 Music: Rear +1 to +2 Gaming: Rear +2 to +3 | Increase rear speakers for movies and games, but lower them for dialogue-heavy content to keep voices clear. |
| LG S65TR | Movies: Rear +2 to +4, Subwoofer +2 to +4 Dialogue/News: Rear 0 to +1, Subwoofer -1 to 0 Music: Rear +1 to +2 Subwoofer +1 to +2 Gaming: Rear +2 to +3, Subwoofer +1 to +2 | Delivers the best surround experience when rear speakers are balanced with the subwoofer. |
| LG S90TY | Movies: Side/Rear +2 to +3, Center +1 to +2, Subwoofer +2 to +4 Dialogue/News: Side/Rear 0 to +1, Center +2 to +4, Subwoofer -1 to 0 Music: Side/Rear +1 to +2, Center 0 to +1 Gaming: Side/Rear +2 to +3, Center +1 to +2 | Premium model with advanced channel controls. Avoid setting rear speakers too high in small rooms. |
| LG S70TY (with optional rear speakers) | Movies: Rear/Side +1 to +3, Subwoofer +2 to +3 Dialogue/News: Rear/Side 0 to +1, Subwoofer -1 to 0 Music: Rear/Side +1 to +2, Subwoofer +1 to +2 Gaming: Rear/Side +2 to +3, Subwoofer +1 to +2 | The base S70TY doesn’t include rear speakers. These settings apply only when optional compatible rear speakers are added. Focus on center-channel clarity for the best everyday experience. |
Tips for Getting the Best Surround Sound
- Movies: Increase the rear and side speaker levels to +2 to +4 for a more immersive surround sound experience.
- Dialogue & TV Shows: Keep rear speakers around 0 to +1 so voices remain clear and centered.
- Music: Use a mild rear speaker boost (+1 to +2) for a wider soundstage without affecting stereo imaging.
- Gaming: Set rear speakers to +2 to +3 to make footsteps, ambient sounds, and directional effects easier to hear.
Pro Tips
- Start with all surround speakers set to 0, then increase them gradually until the surround effect feels natural.
- If dialogue becomes difficult to hear, reduce the rear speaker level before adjusting the bass.
- In small rooms, avoid setting rear speakers above +3, as excessive surround volume can make the sound feel unnatural.
- If your model includes a wireless subwoofer, adjust its level separately instead of relying on rear speakers for more impact.
Room Calibration Matters
Room size, furniture placement, wall reflections, and speaker positioning all affect how your LG soundbar sounds. If your model supports AI Room Calibration or speaker tuning, taking a few minutes to calibrate it can noticeably improve dialogue clarity, surround effects, and bass balance.
Premium LG soundbars automatically analyze your room and optimize the audio, while entry-level models rely on manual tuning using bass, treble, and sound modes.

|---|---|---|---|
| LG SH5A | No AI Room Calibration | Manually adjust Bass, Treble, and use the appropriate Sound Mode. | Everyday TV, Movies, Music |
| LG S30A | Basic Manual Sound Tuning | Fine-tune Bass, Treble, Mid, and Subwoofer settings for your room. | Bedrooms & Small Rooms |
| LG S40T | Manual EQ Only | Use Bass/Treble controls and select the correct Sound Mode. | Everyday TV Viewing |
| LG S40TR | Speaker Level Tuning | Adjust Rear Speaker Levels and Sound Modes to balance surround effects. | Movies & Family Entertainment |

How to Run AI Room Calibration
If your LG soundbar supports AI Room Calibration, follow these steps:
- Place the soundbar, subwoofer, and rear speakers in their final positions.
- Open the LG Sound Bar App (or use your soundbar’s on-screen menu if supported).
- Navigate to Settings → AI Room Calibration or Sound Tuning.
- Start the calibration process and keep the room as quiet as possible.
- Let the soundbar measure the room and automatically optimize the speaker output.
Tip: If the calibrated sound feels too bright or too bass-heavy, make small adjustments to the bass or subwoofer level instead of disabling calibration completely.
Recommended Calibration by Use Case
| Use Case | Calibration Goal |
|---|---|
| Movies | Slightly increase rear/side speaker levels, keep dialogue clear, and avoid excessive bass. |
| Dialogue & News | Prioritize the center channel and slightly reduce the subwoofer for clearer voices. |
| Music | Keep EQ changes subtle to preserve balanced vocals and instruments. |
| Gaming | Increase surround speaker levels slightly for better directional effects and immersion. |
| Late-Night Viewing | Reduce subwoofer and surround speaker levels while keeping dialogue clear. |
Placement Tips for Better Sound
Even the best soundbar settings won’t perform well if the speakers are placed incorrectly.
- Position the subwoofer near a wall or corner, but leave 15–30 cm (6–12 inches) of space to avoid boomy bass.
- Place rear speakers slightly behind your seating position at ear level for the best surround effect.
- Avoid placing the soundbar inside enclosed TV cabinets, as this can block sound dispersion.
- Use HDMI eARC whenever available for the highest-quality Dolby Atmos and DTS:X audio.
- Set your TV’s digital audio output to Auto or Pass Through to preserve surround sound formats.
Which LG Soundbars Benefit Most from Room Calibration?
Room calibration has the biggest impact on premium surround sound systems because they use multiple speakers and advanced audio processing.
Best models for AI Room Calibration:
- LG S95AR
- LG S90TY
- LG S70TY
- LG S65TR
For entry-level models like the SH5A, S30A, and S40T, you’ll usually get better results by choosing the correct Sound Mode and manually adjusting the Bass and Treble settings instead of relying on automatic calibration.
