| TV has limited audio outputs | HDMI ARC/eARC soundbar or optical-compatible system | These connections avoid relying on an old or missing analog output |
Soundbars: the easiest upgrade for TV dialogue
A soundbar is usually the best audio system for TV when the main problem is thin sound, poor dialogue, or too many cables. It sits below the screen, combines several speaker channels in one enclosure, and typically connects through HDMI ARC or eARC.
Dialogue clarity
Look for a dedicated center channel, a dialogue-enhancement mode, and a wide but controlled front soundstage. A center channel anchors voices to the screen instead of allowing speech to drift toward the left or right speaker. Voice modes can help at night, but the highest setting may make speech sound thin or push background music unnaturally low.
Examples of premium all-in-one or expandable soundbars include the Sonos Arc Ultra, Bose Smart Ultra Soundbar, and Sony BRAVIA Theatre Bar 9. These are different designs, but each is aimed at improving speech intelligibility and creating a larger front stage than built-in TV speakers.
Room size and placement
- Small rooms up to about 12 square metres suit compact bars, especially if bass is not a priority.
- Medium rooms around 12–25 square metres benefit from a full-width bar and separate subwoofer.
- Large or open rooms need a longer bar, more output headroom, or a system with rear speakers.
Place the bar directly below the screen with its front edge close to the cabinet edge. Do not push it deep inside a shelf: reflections from the shelf can make voices sound boxy. If the bar has upward-firing Dolby Atmos drivers, leave open space above it. A practical target is at least 10–15 centimetres of clear space, while a very low or enclosed shelf can reduce the height effect.
Connectivity
HDMI eARC is preferable because it can carry lossless Dolby TrueHD-based soundtracks and multichannel PCM from compatible sources. HDMI ARC is sufficient for most streaming services, which commonly use Dolby Digital Plus. Optical audio is reliable but cannot carry many advanced formats and normally does not support modern device-control features as flexibly as HDMI.
Check the number of HDMI inputs before buying. If a soundbar has only one input and your TV cannot pass through every format from a game console or disc player, connect sources to the television and send audio back over eARC.
2.1 systems: better stereo and bass for the money
A 2.1 system has left and right speakers plus a subwoofer, usually driven by a compact amplifier or receiver. It is a strong choice for music, games, and films when you do not need sound effects behind the sofa.
Why 2.1 can sound more natural
Separate left and right speakers can be positioned farther apart than the drivers inside a soundbar. That produces a wider stereo image and more convincing front-to-back depth for music. A real center speaker is absent, however, so dialogue depends on a phantom center created between the two speakers. If you sit well off-center, voices can pull toward one speaker.
For a 2.1 setup, place the left and right speakers at ear height, forming roughly an equilateral triangle with the main seat. If the distance between the speakers is 2 metres, try to sit about 2 metres away. Angle each speaker slightly toward the listener, then adjust the toe-in if voices sound too diffuse.
Subwoofer performance and placement
Subwoofer size is not the same as bass quality. A well-integrated 8-inch subwoofer can sound tighter than a badly positioned 10-inch model. Start by placing the subwoofer near the front wall, about 20–40 centimetres from it, then move it if bass is boomy or weak.
The most useful low-frequency test is the subwoofer crawl: put the subwoofer temporarily at the main listening position, play bass-heavy material, and walk around the room. The location where bass sounds evenest is a good candidate for the subwoofer’s permanent position. This works because room modes create peaks and nulls that no amount of amplifier power can completely remove.
Power and size calculation
Amplifier wattage is not directly comparable across brands, but speaker sensitivity shows why room size matters. Suppose a speaker produces 86 dB from 1 watt at 1 metre. Moving to 3 metres loses roughly 9.5 dB because sound spreads with distance. A 10-watt amplifier adds about 10 dB, leaving approximately 86.5 dB before room reflections and headroom. That is adequate for normal listening, but demanding cinema peaks may require a more capable amplifier and subwoofer.
For a gaming or cinema system, prioritise clean headroom, a proper crossover, and a subwoofer with enough output rather than choosing by the largest wattage number on the box.
Surround systems: the choice for immersion
A surround system adds dedicated side, rear, or height channels. It is the best option for films and games where helicopters, rainfall, vehicles, and environmental effects need to move around the room.
Systems such as the Samsung HW-Q990D combine a soundbar, wireless subwoofer, and rear speakers. A modular arrangement such as a compatible Sonos soundbar with rear speakers and a subwoofer is easier to expand over time. Traditional AV receiver systems offer the most control and upgradeability, but they require more cables, speaker placement, and calibration.
Rear-speaker placement
- Place rear speakers slightly behind the seating position, ideally 0.5–1 metre above ear level.
- Keep the left and right rear speakers at similar distances from the main seat.
- Do not hide them inside a cabinet or place one directly beside the listener and the other several metres away.
- Leave wireless speakers away from crowded Wi-Fi equipment where possible.
Upward-firing height channels work best with a flat, moderately reflective ceiling. They are less convincing with very high, vaulted, absorbent, or irregular ceilings. If the room does not suit reflected sound, a system with physical height speakers is more dependable, although it is much more complex.
Setup complexity
Wireless rears reduce cable runs but do not eliminate setup decisions. You still need power near each rear speaker, a suitable network environment for some systems, and calibration from the main seating position. An AV receiver and passive speakers provide greater control over crossover points and channel levels, but setup can take considerably longer.
Recommended settings for clearer TV sound
Use these as starting points rather than universal rules:
- Set the TV’s digital audio output to Pass-Through or Bitstream when the sound system supports the format.
- Disable the TV’s internal speakers after connecting the external system to prevent echo.
- Start the soundbar’s dialogue enhancement at Low or Medium; use High only when speech remains difficult to understand.
- Set the subwoofer level around the middle of its range, then raise it gradually. Excess bass can mask consonants in dialogue.
- For a speaker-and-subwoofer system, begin with a crossover near 80 Hz. Raise it toward 100–120 Hz only if the main speakers sound strained or small.
- Use a night or dynamic-range mode in apartments, but expect quieter explosions and less bass impact.

What to buy for the best result
Choose a soundbar with a center channel and HDMI eARC if you mainly want clearer dialogue with minimal installation. Choose a 2.1 system if music, stereo imaging, and value matter more than rear effects. Choose surround when your room has a clear viewing position and you regularly watch Atmos films or play games mixed for directional audio.
Before buying, measure the space below the TV, check whether the screen blocks upward-firing drivers, confirm HDMI ARC or eARC compatibility, and plan every subwoofer and rear-speaker power outlet. Those practical details affect the result more than a larger specification number. For most households, a soundbar with a wireless subwoofer is the safest all-round answer; a properly positioned surround system is the superior choice when immersion is the priority.
Frequently asked questions
Can I use a soundbar if my TV does not have HDMI eARC?
Yes, a soundbar can still work through HDMI ARC or optical audio. HDMI ARC is sufficient for most streaming services, while optical is reliable but cannot carry many advanced formats and usually offers less flexible device control. Before buying, check that the soundbar supports the connection your television provides and that its HDMI inputs suit your sources.
Where should I place a soundbar in relation to the television?
Place the soundbar directly below the screen, with its front edge close to the cabinet edge. Avoid pushing it deep inside a shelf because reflections can make voices sound boxy. If it has upward-firing Dolby Atmos drivers, leave at least 10–15 centimetres of clear space above it so the height effect is not reduced.
Will a 2.1 system still provide clear dialogue?
Yes, dialogue can be clear through a phantom center created between the left and right speakers, but it depends more on seating position than a system with a dedicated center channel. Place the speakers at ear height and form roughly an equilateral triangle with the main seat. If you sit well off-center, voices may pull toward one speaker.
How can I find a better location for my subwoofer?
Use the subwoofer crawl. Temporarily place the subwoofer at the main listening position, play bass-heavy material, and walk around the room. The location where bass sounds most even is a good candidate for permanent placement. Start near the front wall, about 20–40 centimetres from it, then move the subwoofer if the bass sounds boomy or weak.
Should I turn off the TV speakers after connecting an external audio system?
Yes, disable the TV’s internal speakers after connecting the external system to prevent echo. Set the television’s digital audio output to Pass-Through or Bitstream when the sound system supports the format. For clearer speech, begin with the soundbar’s dialogue enhancement at Low or Medium, using High only if voices remain difficult to understand.
